Hi Duje,
thanks for your patch!

Unfortunately this is not how leds-gpio works.
You have to have the name be NULL instead of "led_orange" etc, and
put the LEDs in index order, in this case something like;
+ .dev_id = "leds-gpio",
+ .table = {
+ GPIO_LOOKUP_IDX("pxa-gpio", SPITZ_GPIO_LED_ORANGE,
NULL, 0, GPIO_ACTIVE_HIGH),
+ GPIO_LOOKUP_IDX("pxa-gpio", SPITZ_GPIO_LED_GREEN,
NULL, 1, GPIO_ACTIVE_HIGH),
Yours,
