From 7766e16beec3363516306754c9c51a85747d734d Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Thu, 6 Aug 2009 15:03:43 +0000 Subject: [PATCH] sh: LED9, LED10 and LED11 support for Solution Engine 7724 This patch adds support for LED9, LED10 and LED11 on the Solution Engine 7724 board. If CONFIG_PM is enabled then these LEDs are used to show the hardware sleep mode used by the processor. Useful to debug cpuidle.
