How to add modified device tree with PWM control backlight
My circuit board USES PE6 to control the backlight, but it cannot be adjusted. How to modify the device tree of TIM15_CH2.EV1 is not regulated.
EV1:
panel_backlight: panel-backlight {
compatible = "gpio-backlight";
gpios = <&gpiod 13 GPIO_ACTIVE_LOW>;
default-on;
status = "okay";
};
