From e176bb05fec4c00450302a75e81f8da3dc9e309e Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 15 May 2007 11:16:10 +0100 Subject: [PATCH] [ARM] pxa: move pm_ops structure into CPU specific files Move the pm_ops structure into the PXA25x and PXA27x support files. Remove the old pxa_pm_prepare() function, and rename the both pxa_cpu_pm_prepare() functions as pxa_pm_prepare(). We'll fix that later.
