Subject: [ARM] pxa: move pm_ops structure into CPU specific files
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e176bb05fec4c00450302a75e81f8da3dc9e309e;p=openwrt%2Fstaging%2Fblogic.git

[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.
