The hardware in the R329 and D1 SoCs appears to be identical. Patches 4-5 depend on the D1 devicetree series[1], but the rest of this series can/should be merged without them. This driver was tested on the D1 Nezha board. [1]: https://lore.kernel.org/lkml/20221231233851.24923-1-samuel@sholland.org/ Changes in v7: - Use DEFINE_SIMPLE_DEV_PM_OPS Changes in v6: - Drop the A100 DMA controller DT node patch, which was merged via a different series Changes in v5: - 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 - Rename the driver R329 -> A100, since that is the actual original implementation Changes in v4: - Use "default" instead of "maxItems" for timing properties - Depend on LEDS_CLASS_MULTICOLOR Changes in v3: - 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 - 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 Changes in v2: - 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 - Renamed from sunxi-ledc to sun50i-r329-ledc - Added missing "static" to functions/globals as reported by 0day bot Samuel Holland (5): dt-bindings: leds: Add Allwinner A100 LED controller leds: sun50i-a100: New driver for the A100 LED controller arm64: dts: allwinner: a100: Add LED controller node riscv: dts: allwinner: d1: Add LED controller node riscv: dts: allwinner: d1: Add RGB LEDs to boards .../leds/allwinner,sun50i-a100-ledc.yaml | 139 +++++ .../arm64/boot/dts/allwinner/sun50i-a100.dtsi | 14 + .../allwinner/sun20i-d1-lichee-rv-dock.dts | 12 + .../boot/dts/allwinner/sun20i-d1-nezha.dts | 13 + arch/riscv/boot/dts/allwinner/sun20i-d1.dtsi | 6 + .../boot/dts/allwinner/sunxi-d1s-t113.dtsi | 15 + drivers/leds/Kconfig | 9 + drivers/leds/Makefile | 1 + drivers/leds/leds-sun50i-a100.c | 555 ++++++++++++++++++ 9 files changed, 764 insertions(+) create mode 100644 Documentation/devicetree/bindings/leds/allwinner,sun50i-a100-ledc.yaml create mode 100644 drivers/leds/leds-sun50i-a100.c Tested-by: Trevor Woerner Acked-by: Palmer Dabbelt Acked-by: Guo Ren
