+Subject: [PATCH] ARM: OMAP: omap3beagle: add a platform device to hook up the GPIO leds to the leds-gpio driver
+
+omap3beagle: add a platform device to hook up the GPIO leds to the leds-gpio driver
+ * on revision A5 and earlier board the two leds can't be controlled seperately, should be fixed in rev. B and C boards.
