From b6911bba598f5d611f7fdbb87b5af7f1712dbe9d Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 7 May 2014 12:20:57 +0100 Subject: MIPS: Malta: add suspend state entry code This patch introduces code which will enter a suspend state via the PIIX4. This can only be done when PCI support is enabled since it requires access to PCI I/O space and the generation of a special cycle on the PCI bus. In cases where PCI is disabled the mips_pm_suspend function will simply always return an error.
