+Subject: [PATCH 107/247] clk: at91: sama7g5: remove mck0 from parent list of
+ other clocks
+
+MCK0 is changed at runtime by DVFS. Due to this, since not all IPs
+are glitch free aware at MCK0 changes, remove MCK0 from parent list
+of other clocks (e.g. generic clock, programmable/system clock, MCKX).

+
+On SAMA7G5 CPU clock is changed at run-time by DVFS. Since MCK0 and
+CPU clock shares the same parent clock (CPUPLL clock) the MCK0 is
+also changed by DVFS to avoid over/under clocking of MCK0 consumers.
+The lower limit is changed to be able to set MCK0 accordingly by
+DVFS.

+Subject: [PATCH 110/247] clk: at91: clk-master: re-factor master clock
+
+Re-factor master clock driver by splitting it into 2 clocks: prescaller
+and divider clocks. Based on registered clock flags the prescaler's rate
+could be changed at runtime. This is necessary for platforms supporting
+DVFS (e.g. SAMA7G5) where master clock could be changed at run-time.

+Subject: [PATCH 111/247] clk: at91: sama7g5: register cpu clock
+
+Register CPU clock as being the master clock prescaler. This would
+be used by DVFS. The block schema of SAMA7G5's PMC contains also a divider
+between master clock prescaler and CPU (PMC_CPU_RATIO.RATIO) but the
+frequencies supported by SAMA7G5 could be directly received from
+CPUPLL + master clock prescaler and the extra divider would do no work in
+case it would be enabled.

+Subject: [PATCH 112/247] clk: at91: Fix the declaration of the clocks
+
+These are all "early clocks" that require initialization just at
+of_clk_init() time. Use CLK_OF_DECLARE() to declare them.
+
+This also fixes a problem that was spotted when fw_devlink was
+set to 'on' by default: the boards failed to boot. The reason is
+that CLK_OF_DECLARE_DRIVER() clears the OF_POPULATED and causes
+the consumers of the clock to be postponed by fw_devlink until
+the second initialization routine of the clock has been completed.
+One of the consumers of the clock is the timer, which is used as a
+clocksource, and needs the clock initialized early. Postponing the
+timers caused the fail at boot.

+Subject: [PATCH 116/247] net: macb: add capability to not set the clock rate
+
+SAMA7G5's ethernet IPs TX clock could be provided by its generic clock or
+by the external clock provided by the PHY. The internal IP logic divides
+properly this clock depending on the link speed. The patch adds a new
+capability so that macb_set_tx_clock() to not be called for IPs having
+this capability (the clock rate, in case of generic clock, is set at the
+boot time via device tree and the driver only enables it).

+
+Besides the fact that muxclk is optional, muxclk can be set using
+assigned-clocks, removing the need to set it in driver. The warning is
+thus unneeded, so we can transform it in a debug print, eventually to just
+reflect that muxclk was not set by the driver.

+Subject: [PATCH 124/247] regulator: mcp16502: adapt for get/set on other
+ registers
+
+MCP16502 have multiple registers for each regulator (as described
+in enum mcp16502_reg). Adapt the code to be able to get/set all these
+registers. This is necessary for the following commits.

+ platforms
+
+On some platform (e.g. SAMA7G5) LPM pin should be optional as it can
+be controlled explicitly (via shutdown controller registers) in the
+platform specific power saving code to decrease the power consumption
+while suspended as this SoC pin may be connected to other devices that
+could take power saving actions based on its value.

+Subject: [PATCH 131/247] pinctrl: at91-pio4: add support for fewer lines on
+ last PIO bank
+
+Some products, like sama7g5, do not have a full last bank of PIO lines.
+In this case for example, sama7g5 only has 8 lines for the PE bank.
+PA0-31, PB0-31, PC0-31, PD0-31, PE0-7, in total 136 lines.
+To cope with this situation, added a data attribute that is product dependent,
+to specify the number of lines of the last bank.
+In case this number is different from the macro ATMEL_PIO_NPINS_PER_BANK,
+adjust the total number of lines accordingly.
+This will avoid advertising 160 lines instead of the actual 136, as this
+product supports, and to avoid reading/writing to invalid register addresses.

+ operations
+
+The PERID in the CC register for mem2mem operations must match an unused
+PERID.
+The PERID field is 7 bits, but the selected value is 0x3f.
+On later products we can have more reserved PERIDs for actual peripherals,
+thus this needs to be increased to maximum size.
+Changing the value to 0x7f, which is the maximum for 7 bits field.

+Subject: [PATCH 133/247] dmaengine: at_xdmac: add support for sama7g5 based
+ at_xdmac
+
+SAMA7G5 SoC uses a slightly different variant of the AT_XDMAC.
+Added support by a new compatible and a layout struct that copes
+to the specific version considering the compatible string.
+Only the differences in register map are present in the layout struct.
+I reworked the register access for this part that has the differences.
+Also the Source/Destination Interface bits are no longer valid for this
+variant of the XDMAC. Thus, the layout also has a bool for specifying
+whether these bits are required or not.

+Subject: [PATCH 134/247] dmaengine: at_xdmac: add AXI priority support and
+ recommended settings
+
+The sama7g5 version of the XDMAC supports priority configuration and
+outstanding capabilities.
+Add defines for the specific registers for this configuration, together
+with recommended settings.
+However the settings are very different if the XDMAC is a mem2mem or a
+per2mem controller.
+Thus, we need to differentiate according to device tree property.

+Subject: [PATCH 135/247] net: macb: Correct usage of MACB_CAPS_CLK_HW_CHG flag
+
+A new flag MACB_CAPS_CLK_HW_CHG was added and all callers of
+macb_set_tx_clk were gated on the presence of this flag.
+
+-   if (!clk)
++ if (!bp->tx_clk || !(bp->caps & MACB_CAPS_CLK_HW_CHG))
+
+However the flag was not added to anything other than the new
+sama7g5_gem, turning that function call into a no op for all other
+systems. This breaks the networking on Zynq.
+
+The commit message adding this states: a new capability so that
+macb_set_tx_clock() to not be called for IPs having this
+capability
+
+This strongly implies that present of the flag was intended to skip
+the function not absence of the flag. Update the if statement to
+this effect, which repairs the existing users.
+
+Fixes: daafa1d33cc9 ("net: macb: add capability to not set the clock rate")

+SAMA7G5 has different masks for chip ID and chip version on CIDR
+register compared to previous AT91 SoCs. For this the commit adapts

+Subject: [PATCH 144/247] ASoC: atmel-pdc: Use managed DMA buffer allocation
+
+Instead of manually managing its DMA buffers using
+dma_{alloc,free}_coherent() lets the sound core take care of this using
+managed buffers.
+
+On one hand this reduces the amount of boiler plate code, but the main
+motivation for the change is to use the shared code where possible. This
+makes it easier to argue about correctness and that the code does not
+contain subtle bugs like data leakage or similar.

+Subject: [PATCH 146/247] pinctrl: at91-pio4: add support for slew-rate
+
+SAMA7G5 supports slew rate configuration. Adapt the driver for this.
+For output switching frequencies lower than 50MHz the slew rate needs to
+be enabled. Since most of the pins on SAMA7G5 fall into this category
+enabled the slew rate by default.

+
+There is no usrio config defined for default gem config leading to
+a kernel panic devices that don't define a data. This issue can be
+reprdouced with microchip polar fire soc where compatible string
+is defined as "cdns,macb".

+Subject: [PATCH 152/247] ASoC: mchp-i2s-mcc: Add support to select TDM pins
+
+SAMA7G5's I2S-MCC has 4 pairs of DIN/DOUT pins. Since TDM only uses a
+single pair of pins for synchronous capture and playback, the controller
+needs to be told which of the pair is connected. This can be mentioned
+using the "microchip,tdm-data-pair" property from DT. The property is
+optional, useful only if TDM is used. If it's missing, DIN/DOUT 0 pins
+will be used by default.

+Subject: [PATCH 154/247] pinctrl: at91-pio4: Fix slew rate disablement
+
+The slew rate was enabled by default for each configuration of the
+pin. In case the pin had more than one configuration, even if
+we set the slew rate as disabled in the device tree, the next pin
+configuration would set again the slew rate enabled by default,
+overwriting the slew rate disablement.
+Instead of enabling the slew rate by default for each pin configuration,
+enable the slew rate by default just once per pin, regardless of the
+number of configurations. This way the slew rate disablement will also
+work for cases where pins have multiple configurations.

+Subject: [PATCH 155/247] media: atmel: properly get pm_runtime
+
+There are several issues in the way the atmel driver handles
+pm_runtime_get_sync():
+
+- it doesn't check return codes;
+- it doesn't properly decrement the usage_count on all places;
+- it starts streaming even if pm_runtime_get_sync() fails.
+- while it tries to get pm_runtime at the clock enable logic,
+  it doesn't check if the operation was suceeded.
+
+Replace all occurrences of it to use the new kAPI:
+pm_runtime_resume_and_get(), which ensures that, if the
+return code is not negative, the usage_count was incremented.
+
+With that, add additional checks when this is called, in order
+to ensure that errors will be properly addressed.

+ to i
+
+Variable i is being assigned a value however the assignment is
+never read, so this redundant assignment can be removed.
+
+Clean up the following clang-analyzer warning:
+
+drivers/media/platform/atmel/atmel-isc-base.c:975:2: warning: Value
+stored to 'i' is never read [clang-analyzer-deadcode.DeadStores].

+Subject: [PATCH 158/247] media: atmel: atmel-isc: specialize driver name
+ constant
+
+The driver name constant must defined based on product driver, thus moving
+the constant directly where it's required. This will allow each ISC based
+product to define it's own name.

+Subject: [PATCH 159/247] media: atmel: atmel-isc: add checks for limiting
+ frame sizes
+
+When calling the subdev, certain subdev drivers will overwrite the
+frame size and adding sizes which are beyond the ISC's capabilities.
+Thus we need to ensure the frame size is cropped to the maximum caps.

+
+The CBC submodule is a part of the atmel-isc pipeline, and stands for
+Contrast Brightness Control. It is used to apply gains and offsets to the
+luma (Y) and chroma (U, V) components of the YUV elements.
+The CBC submodule should be initialized in the product specific driver
+as it's product specific. Other products can implement it differently

+Subject: [PATCH 168/247] media: atmel: atmel-isc: add RLP to register offsets
+
+The RLP submodule is a part of the atmel-isc pipeline, and stands for
+Rounding,Limiting and Packaging. It used to extract specific data from the
+ISC pipeline. For example if we want to output greyscale 8 bit, we would
+use limiting to 8 bits, and packaging to Luma component only.
+Add rlp to the reg offsets struct.
+This will allow different products to have a different reg offset for this
+particular module.

+
+Newer ISC pipelines have the additional modules of
+Defective Pixel Correction -> DPC itself,
+Defective Pixel Correction -> Green Disparity Correction (DPC_GDC)
+Defective Pixel Correction -> Black Level Correction (DPC_BLC)
+Vertical and Horizontal Scaler -> VHXS
+
+Some products have this full pipeline (sama7g5), other products do not (sama5d2)
+
+Add the modules to the isc base, and also extend the register range to include
+the modules.

+
+The CC submodule is a part of the atmel-isc pipeline, and stands for
+Color Correction. It is used to apply gains and offsets to the
+chroma (U, V) components of the YUV elements.
+Implement the CC submodule initialization, as a product
+specific function, which currently configures the neutral point in color
+correction.

+Subject: [PATCH 178/247] media: atmel: atmel-isc: create callback for GAM
+ submodule product specific
+
+The GAM submodule is a part of the atmel-isc pipeline, and stands for
+Gamma Correction. It is used to apply the gamma curve to the incoming pixels.
+Create a product specific callback for initializing the GAM submodule
+of the pipeline.
+For sama5d2 product, there is no special configuration at this moment,
+thus this function is a noop.

+The RLP submodule is a part of the atmel-isc pipeline, and stands for
+Rounding,Limiting and Packaging. It used to extract specific data from the
+ISC pipeline. For example if we want to output greyscale 8 bit, we would
+use limiting to 8 bits, and packaging to Luma component only.

+Add support for compatible sama7g5-wdt.
+The sama7g5 wdt is the same hardware block as on sam9x60.
+Adapt the driver to use the sam9x60/sama7g5 variant if either
+of the two compatibles are selected (sam9x60-wdt/sama7g5-wdt).

+Subject: [PATCH 190/247] media: atmel: fix build when ISC=m and XISC=y
+
+Building VIDEO_ATMEL_ISC as module and VIDEO_ATMEL_XISC as built-in
+(or viceversa) causes build errors:
+
+ or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o: in function `isc_async_complete':
+ atmel-isc-base.c:(.text+0x40d0): undefined reference to `__this_module'
+ or1k-linux-ld: atmel-isc-base.c:(.text+0x40f0): undefined reference to `__this_module'
+ or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(.rodata+0x390): undefined reference to `__this_module'
+ or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x4): undefined reference to `__this_module'
+ or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x18): undefined reference to `__this_module'
+
+This is caused by the file atmel-isc-base.c which is common code between
+the two drivers.
+
+The solution is to create another Kconfig symbol that is automatically
+selected and generates the module atmel-isc-base.ko. This module can be
+loaded when both drivers are modules, or built-in when at least one of them
+is built-in.

+Subject: [PATCH 193/247] media: atmel: atmel-sama5d2-isc: fix YUYV format
+
+SAMA5D2 does not have the YCYC field for the RLP (rounding, limiting,
+packaging) module.
+The YCYC field is supposed to work with interleaved YUV formats like YUYV.
+In SAMA5D2, we have to use YYCC field, which is used for both planar
+formats like YUV420 and interleaved formats like YUYV.
+Fix the according rlp callback to replace the generic YCYC field (which
+makes more sense from a logical point of view) with the required YYCC
+field.

+ at91_pm_modes_init()
+
+at91_pm_modes_init() checks for proper nodes in device tree and maps
+them accordingly. Up to SAMA7G5 all AT91 SoCs had the same mapping
+b/w power saving modes and different controllers needed in the
+final/first steps of suspend/resume. SAMA7G5 is not aligned with the
+old SoCs thus the code is adapted for this. This patch prepares
+the field for next commits.

+Subject: [PATCH 203/247] ARM: at91: pm: avoid push and pop on stack while
+ memory is in self-refersh
+
+For the previous AT91 RAM controller and self-refresh procedure this
+had no side effects. However, for SAMA7G5 the self-refresh procedure
+doesn't allow this anymore as the RAM controller ports are closed
+before switching it to self-refresh. This commits prepares the code
+for the following ones adding self-refresh and PM support for SAMA7G5.

+Subject: [PATCH 205/247] ARM: at91: pm: add support for waiting MCK1..4
+
+SAMA7G5 has 5 master clocks 0..4. MCK0 is controlled differently than
+MCK 1..4. MCK 1..4 should also be saved/restored in the last phase of
+suspend/resume. Thus, adapt wait_mckrdy to support also MCK1..4.

+Subject: [PATCH 214/247] ARM: at91: pm: save ddr phy calibration data to
+ securam
+
+The resuming from backup mode is done with the help of bootloader.
+The bootloader reconfigure the DDR controller and DDR PHY controller.
+To speed-up the resuming process save the PHY calibration data into
+SECURAM before suspending (securam is powered on backup mode).
+This data will be later used by bootloader in DDR PHY reconfiguration
+process. Also, in the process or recalibration the first 8 words of
+the memory may get corrupted. To solve this, these 8 words are saved
+in the securam and restored by bootloader in the process of PHY
+configuration.

+Subject: [PATCH 215/247] ARM: at91: pm: add backup mode support for SAMA7G5
+
+Adapt at91_pm_backup_init() to work for SAMA7G5. Also, set the LPM pin
+to shutdown controller. This will signal to PMIC that it needs to switch
+to the state corresponding to backup mode.

+Subject: [PATCH 223/247] ARM: at91: pm: do not panic if ram controllers are
+ not enabled
+
+In case PM is enabled but there is no RAM controller information
+in DT the code will panic. Avoid such scenarios by not initializing
+platform specific PM code in case RAM controller is not provided
+via DT.

+Backup area is now switched to VDDIN33 at boot (with the help of

+to VBAT as all the other power sources are cut off. The resuming from
+backup mode is done with the help of bootloader, so there is no need to

+Subject: [PATCH 229/247] ARM: dts: at91: sama7g5ek: add suspend voltage for
+ ddr3l rail
+
+SAMA7G5-EK board has DDR3L type of memory soldered. This needs 1.35V. The
+1.35V for DDR3L rail at run-time is selected by the proper configuration
+on SELV2 pin (for 1.35V it needs to be in high-z state). When suspended
+the MCP16502 PMIC soldered on SAMA7G5-EK will use different sets of
+configuration registers to provide proper voltages on its rail. Run-time
+configuration registers could be configured differently than suspend
+configuration register for MCP16502 (VSEL2 affects only run-time
+configuration). In suspend states the DDR3L memory soldered on SAMA7G5-EK
+switches to self-refresh. Even on self-refresh it needs to be powered by
+a 1.35V rail. Thus, make sure the PMIC is configured properly when system
+is suspended.

+Subject: [PATCH 231/247] ARM: at91: pm: preload base address of controllers in
+ tlb
+
+In suspend/resume procedure for AT91 architecture different controllers
+(PMC, SHDWC, RAM, RAM PHY, SFRBU) are accessed to do the proper settings
+for power saving. Commit f0bbf17958e8 ("ARM: at91: pm: add self-refresh
+support for sama7g5") introduced the access to RAMC PHY controller for
+SAMA7G5. The access to this controller is done after RAMC ports are
+closed, thus any TLB walk necessary for RAMC PHY virtual address will
+fail. In the development branch this was not encountered. However, on
+current kernel the issue is reproducible.
+
+To solve the issue the previous mechanism of pre-loading the TLB with
+the RAMC PHY virtual address has been used. However, only the addition
+of this new pre-load breaks the functionality for ARMv5 based
+devices (SAM9X60). This behavior has been encountered previously
+while debugging this code and using the same mechanism for pre-loading
+address for different controllers (e.g. pin controller, the assumption
+being that other requested translations are replaced from TLB).
+
+To solve this new issue the TLB flush + the extension of pre-loading
+the rest of controllers to TLB (e.g. PMC, RAMC) has been added. The
+rest of the controllers should have been pre-loaded previously, anyway.

+Subject: [PATCH 233/247] ARM: dts: at91: sama7g5ek: to not touch slew-rate for
+ SDMMC pins
+
+With commit c709135e576b ("pinctrl: at91-pio4: add support for slew-rate")
+and commit cbde6c823bfa ("pinctrl: at91-pio4: Fix slew rate disablement")
+the slew-rate is enabled by default for each configured pin. The datasheet
+specifies at chapter "Output Driver AC Characteristics" that HSIO
+drivers (use in SDMMCx and QSPI0 peripherals), don't have a slewrate
+setting but are rather calibrated against an external 1% resistor mounted
+on the SDMMCx_CAL or QSPI0_CAL pins. Depending on the target signal
+frequency and the external load, it is possible to adjust their target
+output impedance. Thus set slew-rate = <0> for SDMMC (QSPI is not enabled
+at the moment in device tree).

+Subject: [PATCH 234/247] clk: at91: re-factor clocks suspend/resume
+
+SAMA5D2 and SAMA7G5 have a special power saving mode (backup mode) where
+most of the SoC's components are powered off (including PMC). Resuming
+from this mode is done with the help of bootloader. Peripherals are not
+aware of the power saving mode thus most of them are disabling clocks in
+proper suspend API and re-enable them in resume API without taking into
+account the previously setup rate. Moreover some of the peripherals are
+acting as wakeup sources and are not disabling the clocks in this
+scenario, when suspending. Since backup mode cuts the power for
+peripherals, in resume part these clocks needs to be re-configured.
+
+The initial PMC suspend/resume code was designed only for SAMA5D2's PMC
+(as it was the only one supporting backup mode). SAMA7G supports also
+backup mode and its PMC is different (few new functionalities, different
+registers offsets, different offsets in registers for each
+functionalities). To address both SAMA5D2 and SAMA7G5 PMC add
+.save_context()/.resume_context() support to each clocks driver and call
+this from PMC driver.

+
+Before going to backup mode architecture specific PM code sets the first
+word in securam (file arch/arm/mach-at91/pm.c, function at91_pm_begin()).
+Thus take this into account when suspending/resuming clocks. This will
+avoid executing unnecessary instructions when suspending to non backup
+modes.

+Subject: [PATCH 237/247] clk: at91: clk-master: add register definition for
+ sama7g5's master clock
+
+SAMA7G5 has 4 master clocks (MCK1..4) which are controlled though the
+register at offset 0x30 (relative to PMC). In the last/first phase of
+suspend/resume procedure (which is architecture specific) the parent
+of master clocks are changed (via assembly code) for more power saving
+(see file arch/arm/mach-at91/pm_suspend.S, macros at91_mckx_ps_enable
+and at91_mckx_ps_restore). Thus the macros corresponding to register
+at offset 0x30 need to be shared b/w clk-master.c and pm_suspend.S.
+commit ec03f18cc222 ("clk: at91: add register definition for sama7g5's
+master clock") introduced the proper macros but didn't adapted the
+clk-master.c as well. Thus, this commit adapt the clk-master.c to use
+the macros introduced in commit ec03f18cc222 ("clk: at91: add register
+definition for sama7g5's master clock").

+Subject: [PATCH 243/247] clk: at91: clk-sam9x60-pll: add notifier for div part
+ of PLL
+
+SAM9X60's PLL which is also part of SAMA7G5 is composed of 2 parts:
+one fractional part and one divider. On SAMA7G5 the CPU PLL could be
+changed at run-time to implement DVFS. The hardware clock tree on
+SAMA7G5 for CPU PLL is as follows:
+
+                       +---- div1 ----------------> cpuck
+                       |
+FRAC PLL ---> DIV PLL -+-> prescaler ---> div0 ---> mck0
+
+The div1 block is not implemented in Linux; on prescaler block it has
+been discovered a bug on some scenarios and will be removed from Linux
+in next commits. Thus, the final clock tree that will be used in Linux
+will be as follows:
+
+                       +-----------> cpuck
+                       |
+FRAC PLL ---> DIV PLL -+-> div0 ---> mck0
+
+It has been proposed in [1] to not introduce a new CPUFreq driver but
+to overload the proper clock drivers with proper operation such that
+cpufreq-dt to be used. To accomplish this DIV PLL and div0 implement
+clock notifiers which applies safe dividers before FRAC PLL is changed.
+The current commit treats only the DIV PLL by adding a notifier that
+sets a safe divider on PRE_RATE_CHANGE events. The safe divider is
+provided by initialization clock code (sama7g5.c). The div0 is treated
+in next commits (to keep the changes as clean as possible).

+Subject: [PATCH 244/247] clk: at91: clk-master: add notifier for divider
+
+SAMA7G5 supports DVFS by changing cpuck. On SAMA7G5 mck0 shares the same
+parent with cpuck as seen in the following clock tree:
+
+                       +----------> cpuck
+                       |
+FRAC PLL ---> DIV PLL -+-> DIV ---> mck0
+
+mck0 could go b/w 32KHz and 200MHz on SAMA7G5. To avoid mck0 overclocking
+while changing FRAC PLL or DIV PLL the commit implements a notifier for
+mck0 which applies a safe divider to register (maximum value of the divider
+which is 5) on PRE_RATE_CHANGE events (such that changes on PLL to not
+overclock mck0) and sets the maximum allowed rate on POST_RATE_CHANGE
+events.

+Subject: [PATCH 245/247] clk: at91: sama7g5: remove prescaler part of master
+ clock
+
+On SAMA7G5 the prescaler part of master clock has been implemented as a
+changeable one. Everytime the prescaler is changed the PMC_SR.MCKRDY bit
+must be polled. Value 1 for PMC_SR.MCKRDY means the prescaler update is
+done. Driver polls for this bit until it becomes 1. On SAMA7G5 it has
+been discovered that in some conditions the PMC_SR.MCKRDY is not rising
+but the rate it provides it's stable. The workaround is to add a timeout
+when polling for PMC_SR.MCKRDY. At the moment, for SAMA7G5, the prescaler
+will be removed from Linux clock tree as all the frequencies for CPU could
+be obtained from PLL and also there will be less overhead when changing
+frequency via DVFS.

+In case clock flags contains CLK_GET_RATE_NOCACHE the clk_rate_get()
+will return the cached rate. Thus, use clk_core_get_rate_recalc() which
+takes proper action when clock flags contains CLK_GET_RATE_NOCACHE.
