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.
