Hi Mike, Stephen, et al.,
As discussed at ELCE last week, here's my RFC introducing a new unified
binding for the Renesas CPG (Clock Pulse Generator) and MSSR (Module
Standby and Software Reset) blocks. 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!
