705d9f8f18 Revert "dt-bindings: clock: renesas,rzg2l-cpg: Update #power-domain-cells = <1> for RZ/G3S"
This reverts commit f33dca9ed6.

Since the configuration order between the individual MSTOP and CLKON
bits cannot be preserved with the power domain abstraction, drop the
power domain IDs.
Currently, there are no device tree users for #power-domain-cell = <1>.

d8abcb7377 dt-bindings: clock: renesas,rzg2l-cpg: Update description for #reset-cells
For the RZ/G2L and similar SoCs, the reset specifier is the reset number
and not the module number. Reflect this in the description for the
'#reset-cells' property.

f33dca9ed6 dt-bindings: clock: renesas,rzg2l-cpg: Update #power-domain-cells = <1> for RZ/G3S
The driver will be modified (in the next commits) to be able to specify
individual power domain IDs for each IP.  The driver will still
support #power-domain-cells = <0>, thus, previous users are not
affected.

The #power-domain-cells = <1> has been instantiated only for RZ/G3S at
the moment, as individual platform clock drivers need to be adapted for
this to be supported on the rest of the SoCs.

Also, the description for #power-domain-cells is updated with links to
per-SoC power domain IDs.

e372aee8c2 dt-bindings: clock: renesas,rzg2l-cpg: Document RZ/G3S SoC
Add documentation for the RZ/G3S CPG.  The RZ/G3S CPG module is almost
identical to the one available in RZ/G2{L,UL}, the exception being some
core clocks as follows:
  - The SD clock is composed of a mux and a divider, and the divider
    has some limitations (div = 1 cannot be set if mux rate is 800MHz),
  - There are 3 SD clocks,
  - The OCTA and TSU clocks are specific to RZ/G3S,
  - PLL1/4/6 are specific to RZ/G3S with its own computation formula.
Even with this RZ/G3S could use the same bindings as RZ/G2L.

Along with documentation bindings for the RZ/G3S (R9A08G045) Clock Pulse
Generator (CPG) core clocks, module clocks and resets were added.

e312ae9207 dt-bindings: clock: renesas,rzg2l: Document RZ/Five SoC
The CPG block on the RZ/Five SoC is almost identical to one found on the
RZ/G2UL SoC. "renesas,r9a07g043-cpg" compatible string will be used on
the RZ/Five SoC so to make this clear, update the comment to include
RZ/Five SoC.
