Subject: [RESEND PATCH v7 0/5] leds: Allwinner A100 LED controller support

[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
