Subject[PATCH v5 0/6] leds: Allwinner A100 LED controller support
Date
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.

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
