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.
