Dear team.
I have written jd9365da panel dts file to bring up MIPI DSI based jd9365da (jadard TFT LCD panel) connected to imx8mm core board directly through MIPI DSI interface. i have taken below
dts files as reference.
dsi1.dtsi#L401
jd9365da dts file entries are given below for reference. requesting to let me know the vdd and vccio backlight entries passed in jd9365da dts file is valid or not? the panel is blank and if back light entry is enabled then failure in attaching jd9365da panel to mipi_dsi@32e10000 bus subsystem. So request to let me know vcc , vdd and backlight entries are valid or not.
