[Resending because it has been a couple of months since v7 with no LED maintainer feedback, and LEDs now have an additional maintainer.]
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.
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.

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
