From 2863e935a59b36d55522af8620112c64a56b4022 Mon Sep 17 00:00:00 2001 From: Arnd Hannemann Date: Sat, 14 Aug 2010 19:45:21 +0000 Subject: ARM: mach-shmobile: AP4EVB: use gpio-leds for leds. This allows control of the leds on the AP4EVB board by kernel events (triggers) like mmc0/mmc1. In userland, the leds won't be available anymore over /sys/class/gpio but via /sys/class/leds.
