2022-04-13clk: renesas: Move RPC core clocksGeert Uytterhoeven1-5/+5
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.

2019-04-02clk: renesas: r8a77980: Fix RPC-IF module clock's parentSergei Shtylyov1-1/+1
Testing has shown that the RPC-IF module clock's parent is the RPCD2 clock, not the RPC one -- the RPC-IF register reads stall otherwise...

R-Car Gen3 Hardware Manual Rev.0.54 documents the relation between the MD13 and MD14 mode pins, and the OSC EXTAL predivider, as used by the OSC clock. Hence augment the configuration structure with all documented predivider values. Add the OSC clock using the configured predivider.
