The A64 SoC features two display pipelines, one has a LCD output, the other has a HDMI output. Add support for simplefb for these pipelines on A64 SoC. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> --- Changes in v4: - Dropped extra clocks. - Added labels to the SimpleFB device tree nodes as boards may have extra regulator for display pipeline. arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+)
