Merge tag 'for_3.7-fixes-cpufreq' of git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm into omap-for-v3.7-rc1/fixes-cpufreq
This series a couple bug fixes and a couple fixes that make this
driver support recently added OMAP-based SoCs.
The 'get_cpu_device' patch is needed due to a change in the OMAP
OMAP PM core code which enforces use of get_cpu_device() instead of
a deprecated OMAP-specific API.
The usage of plat/*.h headers breaks single zImage, so platforms are
cleaning up and/or removing plat/*.h so the driver needs to be fixed
accordingly.
This series is based on the merge of Rafael's pm-for-3.7-rc1 tag into
Linus' master branch: commit 16642a2e7be23bbda013fc32d8f6c68982eab603.
