From 3ef2fb426775fc2ae19b70c318dbdf4a0aeeced7 Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Wed, 2 Apr 2008 21:36:06 +0100 Subject: [ARM] 4903/1: [AT91] SAM9/CAP9 system shutdown Enable system shutdown/power-off on AT91SAM9 and AT91CAP9 based boards. This does not require power-management to be enabled, and the pm_power_off method can be overridden in board-specific files if necessary.
