Subject: ARM: dts: rockchip: add eDP/panel display device nodes for rk3288-evb
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d4da51213a2ce337cb98a468886d5b0bc1e45bcc;p=linux.git
ARM: dts: rockchip: add eDP/panel display device nodes for rk3288-evb
The default eDP panel on RK3288 EVB board is LG LP079QX1-SP0V TFT LCD,
we haven't declared the panel regulator in the 'panel-simple' device
node here, so the specific board like ACT8846 / RK8080 need to support
the panel power supply.
