Support :
[CPU]
- Coretex A15( Z clock) : Supported
- Coretex A7 (Z2 clock) : Not supported
[HW]
- R-CAR H2(ES1.0) : Not supported
- R-CAR H2(ES2.0) : Supported
- R-CAR M2(ES1.0) : Supported
- R-CAR M2(ES2.0) : Supported
- Other HW : Not supported
[DVFS feature]
- DFS : Supported
- DVS : Not supported

Changes since version 1:
- changed "Signed-off-by" and "From" correctly.
- added DA9210 regulator.

Many thanks for these patches to both Benoit and Inami-san.

I'm fine with all of them except the following that I think should be reworked and merged.

[PATCH v2 3/8] ARM: shmobile: Make r8a7790 CPUFreq capable [PATCH v2 7/8] ARM: shmobile: Make r8a7791 CPUFreq capable

So for patch 1,2,4,5,6,8:
