TV BOX board H616 - T95MAX - V4.0 has been equipped with the option of adding two LEDs. The diodes are driven from port "H" bits 6 and 7. Depending on the connection, they can be active in the low or high state. See attached picture 'T95_leds.jpg'. Your DTS file must contain a declaration:
leds {
compatible = "gpio-leds";
led-0 {
function = LED_FUNCTION_POWER;
color = <LED_COLOR_ID_RED>;
gpios = <&pio 7 6 GPIO_ACTIVE_HIGH>; /* PH6 */
default-state = "on";
};
led-1 {
function = LED_FUNCTION_STATUS;
color = <LED_COLOR_ID_GREEN>;
gpios = <&pio 7 7 GPIO_ACTIVE_HIGH>; /* PH7 */
};
};
