NB also overridden by rgbXXX overrides.        backlight-gpio          Defines a GPIO to be used for backlight control                                (default of none).        backlight-pwm           Defines a PWM channel to be used for backlight                                control (default of none). NB Disables audio                                headphone output as that also uses PWM.        backlight-pwm-chan      Choose channel on &pwm node for backlight                                control.
