These bindings are supposed to be more in-line with current CCF best practices, and allow expansion to cover the module reset functionality in the future. They are intended to be used initially for the new R-Car Gen3 SoCs (r8a7795), but we may decide to migrate older SoCs somewhen in the future. - The first patch is an RFC introducing the new bindings. - Patches 2 and 3 are Proof-of-Concepts of the CPG Core Clock Definitions for the already supported R-Car M2-W (r8a7791) SoC, and for the new R-Car H3 (r8a7795) SoC. The idea is to get the bindings (for r8a7795) accepted in v4.4, so we can continue developing and prepare final support for r8a7795 in v4.5. I will post preliminary code and DT patches for both r8a7791 (POC) and r8a7795 (mandatory) as soon as possible. Thanks for your comments!
