+
+ccu_mp_find_best() already computes a best_rate at the same time as the
+best m and p factors. Return it so the caller does not need to duplicate
+the division.

+Subject: [PATCH 007/117] drm/sun4i: Add support for D1 HDMI
+
+D1's HDMI controller contains some platform integration changes.
+It now has no external TMDS clock. The controller also supports HDCP
+without an external clock or reset.
+
+While the maximum HDMI frequency is not explicity stated, the BSP PHY
+driver provides PLL configurations only up to 297 MHz, so use that as
+the max frequency.

+Subject: [PATCH 014/117] mmc: sunxi-mmc: Correct the maximum segment size
+
+According to the DMA descriptor documentation, the lowest two bits of
+the size field are ignored, so the size must be rounded up to a multiple
+of 4 bytes. Furthermore, 0 is not a valid buffer size; setting the size
+to 0 will cause that DMA descriptor to be ignored.
+
+Together, these restrictions limit the maximum DMA segment size to 4
+less than the power-of-two width of the size field.

+Subject: [PATCH 018/117] nvmem: sunxi_sid: Drop the workaround on A64
+
+Now that the SRAM readout code is fixed by using 32-bit accesses, it
+always returns the same values as register readout, so the A64 variant
+no longer needs the workaround. This makes the D1 variant structure
+redundant, so remove it.

+to its provider device's stride.
+
+These cells can be represented in the DT using the "bits" property if
+that property allows offsets up to the full stride. 63 is chosen
+assuming that NVMEM devices will not have strides larger than 8 bytes.

+Subject: [PATCH 020/117] regulator: dt-bindings: Add Allwinner D1 LDOs
+
+The Allwinner D1 SoC contains two pairs of in-package LDOs. One pair is
+for general purpose use. LDOA generally powers the board's 1.8 V rail.
+LDOB generally powers the in-package DRAM, where applicable.
+
+The other pair of LDOs powers the analog power domains inside the SoC,
+including the audio codec, thermal sensor, and ADCs. These LDOs require
+a 0.9 V bandgap voltage reference. The calibration value for the voltage
+reference is stored in an eFuse, accessed via an NVMEM cell.
+
+Neither LDO control register is in its own MMIO range; instead, each
+regulator device relies on a regmap/syscon exported by its parent.
+
+Series-changes: 2
+ - Remove syscon property from bindings
+ - Update binding examples to fix warnings and provide context
+
+Series-changes: 3
+ - Add "reg" property to bindings
+ - Add "unevaluatedProperties: true" to regulator nodes
+ - Minor changes to regulator node name patterns
+ - Remove system-ldos example (now added in patch 3)
+
+Series-changes: 4
+ - Fix the order of the maintainer/description sections
+ - Replace unevaluatedProperties with "additionalProperties: false"

+Subject: [PATCH 021/117] regulator: sun20i: Add support for Allwinner D1 LDOs
+
+D1 contains two pairs of LDOs. Since they have similar bindings, and
+they always exist together, put them in a single driver.
+
+The analog LDOs are relatively boring, with a single linear range. Their
+one quirk is that a bandgap reference must be calibrated for them to
+produce the correct voltage.
+
+The system LDOs have the complication that their voltage step is not an
+integer, so a custom .list_voltage is needed to get the rounding right.
+
+Series-changes: 2
+ - Use decimal numbers for .n_voltages instead of field widths
+ - Get the regmap from the parent device instead of a property/phandle
+
+Series-changes: 3
+ - Adjust control flow in sun20i_regulator_get_regmap() for clarity

+Subject: [PATCH 028/117] riscv: dts: allwinner: Add the D1 SoC base devicetree
+
+D1 is a SoC containing a single-core T-HEAD Xuantie C906 CPU, as well as
+one HiFi 4 DSP. The SoC is based on a design that additionally contained
+a pair of Cortex A7's. For that reason, some peripherals are duplicated.
+
+This devicetree includes all of the peripherals that already have a
+documented binding.

+Subject: [PATCH 029/117] riscv: dts: allwinner: Add Allwinner D1 Nezha
+ devicetree
+
+"D1 Nezha" is Allwinner's first-party development board for the D1 SoC.
+It was shipped with 512M, 1G, or 2G of DDR3. It supports onboard audio,
+HDMI, gigabit Ethernet, WiFi and Bluetooth, USB 2.0 host and OTG ports,
+plus low-speed I/O from the SoC and a GPIO expander chip.
+
+Most other D1 boards copied the Nezha's power tree, with the 1.8V rail
+powered by the SoCs internal LDOA, analog domains powered by ALDO, and
+the rest of the board powered by always-on fixed regulators. Some (but
+not all) boards also copied the PWM CPU regulator. To avoid duplication,
+factor out the out the regulator references that are common across all
+known boards.

+Subject: [PATCH 030/117] riscv: dts: allwinner: Add Sipeed Lichee RV
+ devicetrees
+
+Sipeed manufactures a "Lichee RV" system-on-module, which provides a
+minimal working system on its own, as well as a few carrier boards. The
+"Dock" board provides audio, USB, and WiFi. The "86 Panel" additionally
+provides 100M Ethernet and a built-in display panel.
+
+The 86 Panel repurposes the USB ID and VBUS detection GPIOs for its RGB
+panel interface, since the USB OTG port is inaccessible inside the case.

+
+The MangoPi MQ Pro is a tiny SBC with a layout compatible to the
+Raspberry Pi Zero. It includes the Allwinner D1 SoC, 512M or 1G of DDR3,
+and an RTL8723DS-based WiFi/Bluetooth module.
+
+The board also exposes GPIO Port E via a connector on the end of the
+board, which can support either a camera or an RMII Ethernet PHY. The
+additional regulators supply that connector.

+
+The 100ask Dongshan Nezha STU is a system-on-module that can be used
+standalone or with a carrier board. The SoM provides gigabit Ethernet,
+HDMI, a USB peripheral port, and WiFi/Bluetooth via an RTL8723DS chip.
+
+The "DIY" carrier board exposes almost every pin from the D1 SoC to 0.1"
+headers, but contains no digital circuitry, so it does not have its own
+devicetree.

+Subject: [PATCH 033/117] riscv: dts: allwinner: Add ClockworkPi and DevTerm
+ devicetrees
+
+Clockwork Tech manufactures several SoMs for their RasPi CM3-compatible
+"ClockworkPi" mainboard. Their R-01 SoM features the Allwinner D1 SoC.
+The R-01 contains only the CPU, DRAM, and always-on voltage regulation;
+it does not merit a separate devicetree.
+
+The ClockworkPi mainboard features analog audio, a MIPI-DSI panel, USB
+host and peripheral ports, an Ampak AP6256 WiFi/Bluetooth module, and an
+X-Powers AXP228 PMIC for managing a Li-ion battery.
+
+The DevTerm is a complete system which extends the ClockworkPi mainboard
+with a pair of expansion boards. These expansion boards provide a fan, a
+keyboard, speakers, and a thermal printer.

+Subject: [PATCH 034/117] riscv: Add the Allwinner SoC family Kconfig option
+
+Allwinner manufactures the sunxi family of application processors. This
+includes the "sun8i" series of ARMv7 SoCs, the "sun50i" series of ARMv8
+SoCs, and now the "sun20i" series of 64-bit RISC-V SoCs.
+
+The first SoC in the sun20i series is D1, containing a single T-HEAD
+C906 core. D1s is a low-pin-count variant of D1 with co-packaged DRAM.
+
+Most peripherals are shared across the entire chip family. In fact, the
+ARMv7 T113 SoC is pin-compatible and almost entirely register-compatible
+with the D1s.
+
+This means many existing device drivers can be reused. To facilitate
+this reuse, name the symbol ARCH_SUNXI, since that is what the existing
+drivers have as their dependency.

+Subject: [PATCH 035/117] riscv: defconfig: Enable the Allwinner D1 platform
+ and drivers
+
+Now that several D1-based boards are supported, enable the platform in
+our defconfig. Build in the drivers which are necessary to boot, such as
+the pinctrl, MMC, RTC (which provides critical clocks), SPI (for flash),
+and watchdog (which may be left enabled by the bootloader). Other common
+onboard peripherals are enabled as modules.
+
+Cover-letter:
+riscv: Allwinner D1 platform support
+This series adds the Kconfig/defconfig plumbing and devicetrees for a
+range of Allwinner D1-based boards. Many features are already enabled,
+including USB, Ethernet, and WiFi.
+
+The SoC devicetree uses bindings from the following series which have
+not yet been merged:
+- SRAM controller:
+ https://lore.kernel.org/lkml/20220815041248.53268-1-samuel@sholland.org/
+- NVMEM cell bits property change:
+ https://lore.kernel.org/lkml/20220814173656.11856-1-samuel@sholland.org/
+- In-package LDO regulators:
+ https://lore.kernel.org/lkml/20220815043436.20170-1-samuel@sholland.org/
+
+All three of these are required to set the correct I/O domain voltages
+in the pin controller, which I would consider important to have in the
+initial version of the devicetree.
+
+The SoC devicetree does contain one small hack to avoid a dependency on
+the audio codec binding, since that is not ready yet: the codec node
+uses a bare "simple-mfd", "syscon" compatible.

+Subject: [PATCH 037/117] dt-bindings: crypto: sun8i-ce: Add compatible for D1
+
+D1 has a crypto engine similar to the one in other Allwinner SoCs.
+Like H6, it has a separate MBUS clock gate.
+
+It also requires the internal RC oscillator to be enabled for the TRNG
+to return data. This is likely the case for earlier variants as well,
+but the clock drivers for earlier SoCs did not allow disabling the RC
+oscillator.
+
+Series-changes: 2
+ - Add TRNG clock

+Subject: [PATCH 038/117] crypto: sun8i-ce - Add TRNG clock to D1 variant
+
+At least the D1 variant requires a separate clock for the TRNG.
+Without this clock enabled, reading from /dev/hwrng reports:
+
+ sun8i-ce 3040000.crypto: DMA timeout for TRNG (tm=96) on flow 3
+
+Experimentation shows that the necessary clock is the SoC's internal
+RC oscillator. This makes sense, as the oscillator's frequency
+variations can be used as a source of randomness.
+
+Since D1 does not yet have a device tree, we can update this variant
+without breaking anything.

+
+While it was not officially documented until recently (e.g. A50), the
+hwspinlock block can trigger an interrupt when a lock is unlocked. This
+capability is used by Allwinner's ARISC firmware, it has been verified
+to work on A64, and the IRQ numbers are reserved as far back as A31.
+So most likely this feature has always been available.
+
+Even though the Linux hwspinlock framework cannot make use of the IRQ,
+the capability should still be documented in the device tree.

+
+The Allwinner A100, R329, and D1 SoCs contain an LED controller designed
+to drive a series of RGB LED pixels. It supports PIO and DMA transfers,
+and has configurable timing and pixel format. All three implementations
+appear to be identical, so use the oldest as the fallback compatible.
+
+Series-changes: 2
+ - Fixed typo leading to duplicate t1h-ns property
+ - Removed "items" layer in definition of dmas/dma-names
+ - Replaced uint32 type reference with maxItems in timing properties
+
+Series-changes: 3
+ - Removed quotes from enumeration values
+ - Added vendor prefix to timing/format properties
+ - Renamed "format" property to "pixel-format" for clarity
+ - Dropped "vled-supply" as it is unrelated to the controller hardware
+
+Series-changes: 4
+ - Use "default" instead of "maxItems" for timing properties
+
+Series-changes: 5
+ - A100 contains the original implementation, so use that as the base
+ compatible string, and rename the binding to match
+ - Add "unevaluatedProperties: false" to the child multi-led binding

+ controller
+
+Some Allwinner sunxi SoCs, starting with the A100, contain an LED
+controller designed to drive RGB LED pixels. Add a driver for it using
+the multicolor LED framework, and with LEDs defined in the device tree.
+
+Series-changes: 2
+ - Renamed from sunxi-ledc to sun50i-r329-ledc
+ - Added missing "static" to functions/globals as reported by 0day bot
+
+Series-changes: 3
+ - Added vendor prefix to timing/format properties
+ - Renamed "format" property to "pixel-format" for clarity
+ - Dropped "vled-supply" as it is unrelated to the controller hardware
+ - Changed "writesl" to "iowrite32_rep" so the driver builds on hppa
+
+Series-changes: 4
+ - Depend on LEDS_CLASS_MULTICOLOR
+
+Series-changes: 5
+ - Rename the driver R329 -> A100, since that is the actual original
+ implementation

+Cover-letter:
+leds: Allwinner A100 LED controller support
+This series adds bindings and a driver for the RGB LED controller found
+in some Allwinner SoCs, starting with A100. The hardware in the R329 and
+D1 SoCs appears to be identical.
+
+Patch 3 is included because the LED controller binding requires the DMA
+properties. That patch was sent previously[1], but never got merged.
+
+Patches 5-6 depend on the D1 devicetree series[2], but the rest of this
+series can be merged without them.
+
+This driver was tested on the D1 Nezha board.

++Allwinner sun8i-v536 SoC PWM controller
++
++Required properties:
++ - compatible: should be "allwinner,<name>-pwm"
++ "allwinner,sun8i-v833-pwm"
++ "allwinner,sun8i-v536-pwm"
++ "allwinner,sun50i-r818-pwm"
++ "allwinner,sun50i-a133-pwm"
++ "allwinner,sun50i-r329-pwm"
++ - reg: physical base address and length of the controller's registers
++ - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
++ the cells format.
++ - clocks: From common clock binding, handle to the parent clock.
++ - resets: From reset clock binding, handle to the parent clock.
++
++Example:
++
++ pwm: pwm@300a0000 {
++ compatible = "allwinner,sun50i-r818-pwm";
++ reg = <0x0300a000 0x3ff>;
++ clocks = <&ccu CLK_BUS_PWM>;
++ resets = <&ccu RST_BUS_PWM>;

+The driver does not need to care about which variants have a reset;
+the devicetree binding already enforces that the necessary resources are
+provided. Simplify the logic by always calling the optional getter,
+which will return NULL if no reset reference is found.
+
+Also clean up the error handling, which should not print a misleading

+ clocks
+
+On older variants of the hardware, the RX and TX blocks share a single
+module clock, named "spdif" in the DT binding. The D1 variant has
+separate RX and TX clocks, so the TX module clock is named "tx" in the
+binding. To support this, supply the clock name in the quirks structure.
+
+Since the driver supports only TX, only the TX clock name is needed.

+Subject: [PATCH 071/117] ASoC: sun4i-spdif: Add support for the D1 variant
+
+The D1 variant is similar to the H6 variant, except for its clock setup.
+The clock tree changes impact some register fields on the RX side, but
+those are not yet relevant, because RX is not supported by this driver.

+Subject: [PATCH 079/117] dt-bindings: thermal: sun8i: Add compatible for D1
+
+D1 contains a thermal sensor similar to other Allwinner SoCs. Like the
+H3 variant, it contains only one channel.
+
+D1's thermal sensor gets a reference voltage from AVCC. This may always
+have been the case; it is explicitly documented in the SoC user manuals
+since at least H616. However, it was not as important on earlier SoCs,
+because those reference designs foreced AVCC always-on by connecting it
+to the PLL power supply.
+
+Now, since D1 only uses AVCC for other optional peripherals, this supply
+could be turned off at runtime, so it must be made explicit in the DTS.

+Subject: [PATCH 086/117] drm/sun4i: decouple TCON_DCLK_DIV value from
+ pll_mipi/dotclock ratio
+
+Observations showed that an actual refresh rate differs from the intended.
+Specifically, in case of 4-lane panels it was reduced by 1/3, and in case of
+2-lane panels by 2/3.
+
+BSP code apparently distinguishes between a `dsi_div` and a 'tcon inner div'.
+While this 'inner' divider is under DSI always 4, the `dsi_div` is defined
+as a number of bits per pixel over a number of DSI lanes. This value is then
+involved in setting the rate of PLL_MIPI.
+
+I couldn't really figure out how to fit this into the dotclock driver,
+so I opted for this hack where the requested rate is adjusted in such a way
+that the sun4i_dotclock driver can remain untouched.

+Subject: [PATCH 088/117] drm/sun4i: tcon_top: Register reset, clock gates in
+ probe
+
+TCON TOP is processing clock gates and reset control for
+TV0, TV1 and DSI channels during bind and release the same
+during unbind component ops.
+
+The usual DSI initialization would setup all controller
+clocks along with DPHY clocking during probe.
+
+Since the actual clock gates (along with DSI clock gate)
+are initialized during ton top bind, the DPHY is failed to
+get the DSI clock during that time.
+
+To solve, this circular dependency move the reset control,
+clock gate registration from bind to probe and release the
+same from unbind to remove.
+
+This eventually give a chance DPHY to initialize the DSI
+clock gate.

+Subject: [PATCH 095/117] dt-bindings: display: sun6i-dsi: Add the A100 variant
+
+The "40nm" MIPI DSI controller found in the A100 and D1 SoCs has the
+same register layout as previous SoC integrations. However, its module
+clock now comes from the TCON, which means it no longer runs at a fixed
+rate, so this needs to be distinguished in the driver.
+
+The controller also now uses pins on Port D instead of dedicated pins,
+so it drops the separate power domain.
+
+Commit-notes:
+Removal of the vcc-dsi-supply is maybe a bit questionable. Since there
+is no "VCC-DSI" pin anymore, it's not obvious which pin actually does
+power the DSI controller/PHY. Possibly power comes from VCC-PD or VCC-IO
+or VCC-LVDS. So far, all boards have all of these as always-on supplies,
+so it is hard to test.

+Subject: [PATCH 097/117] drm/sun4i: dsi: Add the A100 variant
+
+The A100 variant of the MIPI DSI controller now gets its module clock
+from the TCON via the TCON TOP, so the clock rate cannot be set to a
+fixed value. Otherwise, it appears to be the same as the A31 variant.
+
+Cover-letter:
+drm/sun4i: dsi: Support the A100/D1 controller variant
+This series adds support for the digital part of the DSI controller
+found in the A100 and D1 SoCs (plus T7, which is not supported by
+mainline Linux). There are two changes to the hardware integration:
+ 1) the module clock routes through the TCON TOP, and
+ 2) the separate I/O domain is removed.
+
+The actual register interface appears to be the same as before. The
+register definitions in the D1 BSP exactly match the A64 BSP.
+
+The BSP describes this as the "40nm" DSI controller variant. There is
+also a "28nm" variant with a different register interface; that one is
+found in a different subset of SoCs (V5 and A50).
+
+A100/D1 also come with an updated DPHY, described by the BSP as a
+"combo" PHY, which is now also used for LVDS channel 0. (LVDS and DSI
+share the same pins on Port D.) Since that is a different subsystem,
+I am sending that as a separate series.

+
+Before commit 44c922572952 ("RISC-V: enable XIP"), these macros cast
+their argument to unsigned long. That commit moved the cast after an
+assignment to an unsigned long variable, rendering it ineffectual.
+Move the cast back, so we can remove the cast at each call site.

+A100 features an updated DPHY, which moves PLL control inside the DPHY

+does not affect the "clocks" property because the link between PLL-MIPI
+and the DPHY was never represented in the devicetree.) It also requires

+Subject: [PATCH 106/117] phy: allwinner: phy-sun6i-mipi-dphy: Add the A100
+ DPHY variant
+
+A100 features an updated DPHY, which moves PLL control inside the DPHY
+register space (previously the PLL was controlled from the CCU). It also
+requires a modified analog power-on sequence. This "combo PHY" can also
+be used as an LVDS PHY, but that is not yet supported by the driver.
+
+Cover-letter:
+phy: allwinner: phy-sun6i-mipi-dphy: Add the A100 DPHY
+This series adds support for the updated DPHY found in a couple of
+recent Allwinner SoCs. The first three patches fix an omission in the
+existing binding. The remaining patches add the new hardware variant.

+Subject: [PATCH 107/117] drm: panel: Add driver for Clockwork cwd686 panel
+
+The Clockwork DevTerm (all models) uses a 6.86" IPS display
+of unknown provenance, which uses the Chipone ICNL9707 IC driver.
+
+The display panel I have has two model numbers: TXW686001 and WTL068601G,
+but cannot find any manufacturer associated with either, so opting for the
+Clockwork model number.
+
+This driver is based on the GPL-licensed driver released by Clockwork,
+authored by Pinfan Zhu, with some additional cleanup, rotation support,
+and display sleep re-enabling done by me.
+
+Original driver here for reference: https://github.com/clockworkpi/DevTerm/blob/main/Code/patch/armbian_build_a06/patch/kernel-004-panel.patch
+Display IC datasheet provided here: https://github.com/clockworkpi/DevTerm/blob/main/Schematics/ICNL9707_Datasheet.pdf
