- 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.
