From b9416f03fd9f809225a90f63b2fbc86f90010eab Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Sun, 10 Jul 2011 10:38:53 +0200 Subject: ARM: mach-shmobile: sh7372 late pm domain off Add sh7372 specific code to power down unused pm domains. This should really be replaced by some generic PM core code IMO, but until that happens this patch makes sure we don't waste power by leaving unused power domains on.
