But now using the macros this is not needed anymore, so I don't think is necessary to keep that on the comments. Best regards, Javier

The GPIO for LED D1 on the omap4-panda a1-a3 rev and the omap4-panda-es are different. A1-A3 = gpio_wk7 ES = gpio_110 There is no change to LED D2 Abstract away the pinmux and the LED definitions for the two boards into the respective DTS files.
