    Subject[PATCH 3/5] arm64: dts: allwinner: a64: add simplefb for A64 SoC
    Date
    The A64 SoC features two display pipelines, one has a LCD output, the
    other has a HDMI output.

    Add support for simplefb for the LCD output. Tested on Teres I.

    This patch was inspired by work of Icenowy Zheng.
