Subject: sh: LED9, LED10 and LED11 support for Solution Engine 7724
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=7766e16beec3363516306754c9c51a85747d734d;p=deliverable%2Flinux.git

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.
