From dadaa1c2c0eddc09d11d7494b040c3f331ecd98f Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 7 May 2014 12:22:12 +0100 Subject: MIPS: Malta: support powering down This patch powers down the Malta in response to a power off command (eg. poweroff or shutdown -P). It may then be powered back up by pressing the "ON/NMI" button (S4) on the board. In cases where the power off state cannot be entered (eg. because the required PCI support is disabled) the current reset behaviour will be used as a fallback.
