2023-08-15clk: renesas: rcar-gen3: Add ADG clocksKuninori Morimoto
R-Car Sound needs to enable "ADG" on RMSTPCR9/SMSTPCR9 bit 22 to use clk_i which came from the internal S0D4 or ZA2 clock.

2022-04-13clk: renesas: Move RPC core clocksGeert Uytterhoeven
The RPC and RPCD2 core clocks were added to the sections for internal core clocks, while they are core clock outputs, visible from DT. Move them to the correct sections. Rename the ".rpc" clock on R-Car S4 to "rpc". Fixup nearby whitespace to increase uniformity.
