I can't clearly tell the difference between LCD display and panel.
I've added panel-common because of 'backlight' and 'reset-gpios'
properties. I've looked at 'sitronix,st7735r.yaml',
'ilitek,ili9486.yaml' as examples. SPI controlled LCD displays, but in
color.
In fact 'reset-gpios' is already in my yaml. I might just add the
'backlight' property explicitly and remove this dependency. Should I?
