[PATCH v3 0/5] Add clock driver for Actions S700 SoC

[PATCH v3 0/5] Add clock driver for Actions S700 SoC

[Saravanan Sekar]

Changelog v3:
- Splitted uart clock DTS changes into separate patch
- Splitted REGMAP Kconfig selection into separate patch
- General naming convention as "Actions Semi" in dt-binding documentation
- Patch re-oredering
- Cleanup and fixed review findings

Changelog v2:
Fixed 0 day compilation warning
Modified existing dts Actions S900 clock bindings common to Actions
Soc family

This patchset adds clock support for Actions Semi OWL series S700 SoC
with relevant clock bindings and device tree info. 

Changed the UART clock using CMU instance and changes are tested in
cubieboard7

Thanks and regards,
Saravanan,
Parthiban

The important think you are doing is adding the S700, so the subject 
should reflect that. Renaming is secondary. Please the subject and 
commit msg wording is not very coherent.

These are inputs and outputs? Does the CMU block actually control them? 
If not, then they should not be part of this number space.

Not really any point to have the base define because you can never 
change it. It's an ABI.
