Hi Duje, thanks for your patch!

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, Linus Walleij

Sharp's Spitz board still uses the legacy GPIO interface for configuring its two onboard LEDs. Convert them to use the GPIO descriptor interface.
