Having added CPUFreq support to the Cortex A15 cores on APE6 (r8a73a4) and 
DT support to the max8973 regulator driver it is now possible to implement 
CA15 CPUFreq support on APE6EVM, using a max8972 PMU to adjust SoC's DVFS
voltage. This series depends on earlier

"ARM: shmobile: r8a73a4: wait for completion when kicking the clock"
https://patchwork.kernel.org/patch/2601071/
"ARM: shmobile: r8a73a4: implement CPU clock scaling for CPUFreq"
https://patchwork.kernel.org/patch/2601111/

and requires the following max8973 patches:

"regulators: max8973: fix multiple instance support"

"regulators: max8973: initial DT support"
