Add the necessary DT changes to enable eDP0 on RK3588S EVB1 board: - Set pinctrl of pwm12 for backlight - Enable edp0/hdptxphy0/vp2 - Add aux-bus/panel nodes The eDP panel model used on this board is LP079QX1_SP0V. Due to the broken identification, the compatible of panel node is set to "lg,lp079qx1-sp0v" rather than "edp-panel". The log related to this issue may be like: [ 0.623793] panel-simple-dp-aux aux-fdec0000.edp: Unknown panel ETC 0x0000, using conservative timings Signed-off-by: Damon Ding <damon.ding@rock-chips.com> --- Changes in v2: - Remove brightness-levels and default-brightness-level properties in backlight node. - Add the detail DT changes to commit message. Changes in v3: - Use aux-bus instead of platform bus for edp-panel. Changes in v4: - Add comments related to the use of panel compatible "lg,lp079qx1-sp0v" in the commit message. --- .../boot/dts/rockchip/rk3588s-evb1-v10.dts | 52 +++++++++++++++++++ 1 file changed, 52 insertions(+)
