[PATCH v2 0/3] ARM: shmobile: r8a73a4: add I2C devices and CPUFreq support

[PATCH v2 0/3] ARM: shmobile: r8a73a4: add I2C devices and CPUFreq support

[Guennadi Liakhovetski]

CPUFreq voltage scaling support for APE6EVM uses an I2C PMIC. This patch 
series adds support for I2C on r8a73a4 and adds required hooks to APE6EVM. 
This patch series is identical to v1 with the only difference, that a 
patch from it has been split into two upon maintainer's request.

[PATCH 3/3] ARM: shmobile: ape6evm: add CPUFreq support

[Guennadi Liakhovetski]

This patch adds OPPs to the CA15 DT node and a max8973 DT node to support
clock and voltage scaling, using the cpufreq-cpu0 CPUFreq driver.
