+Subject: [PATCH 02/14] riscv: dts: allwinner: Update opp table to allow CPU
+ frequency scaling
+
+Two OPPs are currently defined for the D1/D1s; one at 408MHz and
+another at 1.08GHz. Switching between these can be done with the
+"sun50i-cpufreq-nvmem" driver. This patch populates the opp table
+appropriately, inspired by
+https://github.com/Tina-Linux/linux-5.4/blob/master/arch/riscv/boot/dts/sunxi/sun20iw1p1.dtsi
+
+The supply voltages are PWM-controlled, but support for that IP
+is still in the works. So stick to a target vdd-cpu supply of 0.9V,
+which seems to be the default on most D1 boards.

-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.

+Date: Sat, 5 Aug 2023 21:05:03 +0300
+Subject: [PATCH 09/14] ASoC: sunxi: sun4i-codec: add basic support for D1
+ audio codec
+
+Allwinner D1 has an audio codec similar to earlier ones, but it comes
+with 3 channel ADC instead of 2, and many registers are moved.
+
+Add basic support for it.

+Subject: [PATCH 10/14] ASoC: sunxi: Add new driver for Allwinner D1/T113s
+ codec's analog path controls
+
+The internal codec on D1/T113s is split into 2 parts like the previous
+ones. But now analog path controls registers are mapped directly
+on the bus, right after the registers of the digital part.
+
+Add an ASoC component driver for it. This should be tied to the codec
+audio card as an auxiliary device.

-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.

-
-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.

-Subject: [PATCH 019/117] dt-bindings: nvmem: Allow bit offsets greater than a
- byte
-
-Some NVMEM devices contain cells which do not start at a multiple of the
-device's stride. However, the "reg" property of a cell must be aligned
-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

- regulators child
-
-Some sunxi SoCs have in-package regulators controlled by a register in
-the system control MMIO block. Allow a child node for these regulators
-in addition to SRAM child nodes.
-
-Commit-changes: 2
- - New patch for v2
-
-Series-changes: 3
- - Require the regulators node to have a unit address
- - Reference the regulator schema from the SRAM controller schema
- - Move the system LDOs example to the SRAM controller schema
- - Reorder the patches so the example passes validation
-
-Series-changes: 4
- - Remove unevaluatedProperties from regulators schema reference

-regulator: Add support for Allwinner D1 LDOs
-This series adds bindings and a driver for the two pairs of LDOs
-inside the Allwinner D1 SoC.
-
-A binding and driver change is required for the SRAM controller, to
-accept the regulators device as its child node. The new example in the
-SRAM controller binding uses the compatible string added in this series:

-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.

-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.

-Subject: [PATCH 031/117] riscv: dts: allwinner: Add MangoPi MQ Pro devicetree
-
-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.

- devicetree
-
-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.

-Like H6, it has a separate MBUS clock gate.

-It also requires the internal RC oscillator to be enabled for the TRNG

-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.

-Subject: [PATCH 045/117] dt-bindings: hwlock: sun6i: Add interrupts property
-
-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.

-Subject: [PATCH 054/117] dt-bindings: leds: Add Allwinner A100 LED controller
-
-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

-Subject: [PATCH 055/117] leds: sun50i-a100: New driver for the A100 LED
- 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.

-The driver does not need to care about which variants have a reset;

-

-Subject: [PATCH 070/117] ASoC: sun4i-spdif: Add support for separate RX/TX
- 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 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.

-Subject: [PATCH 098/117] riscv: Move cast inside kernel_mapping_[pv]a_to_[vp]a
-
-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.

-Document this capability in order to accurately describe the hardware.
-
-The DPHY has no interrupt number provided in the vendor documentation

-does not affect the "clocks" property because the link between PLL-MIPI

-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
