Merge tag 'omap-for-v3.7-rc1/fixes-cpufreq-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
These were agreed to be merged via arm soc tree as Rafael
is on vacation.
From Kevin Hilman <khilman@deeprootsystems.com>:
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.
* tag 'omap-for-v3.7-rc1/fixes-cpufreq-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: PM: MPU DVFS: use generic CPU device for MPU-SS
cpufreq: OMAP: use get_cpu_device() instead of omap_device API
cpufreq: OMAP: fix clock usage to be SoC independent, remove plat/ includes
cpufreq: OMAP: remove unused <plat/omap-pm.h>
cpufreq: OMAP: ensure valid clock rate before scaling
