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
