* clk: renesas: r8a779f0: Fix Ethernet Switch clocksGeert Uytterhoeven2022-11-161-2/+2
| | | | | | | | | | | The RSwitch2 and EtherTSN-IF clocks were accidentally mixed up. While at it, rename them to better match the (future) documentation.

| | | | | | | | | | | | | | | | As serial communication requires a clean clock signal, the Serial Communication Interfaces with FIFO (SCIF) are clocked by a clock that is not affected by Spread Spectrum or Fractional Multiplication. Hence change the parent clocks for the SCIF modules from the S0D12_PER clock to the SASYNCPERD4 clock (which has the same clock rate), cfr. R-Car S4-8 Hardware User's Manual rev. 0.81.

| | | | | | | | | | | | | | According to Section 8.1.2 Figure 8.1.1 ("Block Diagram of CPG"), Note 22 ("RSW2 divider"), and Table 8.1.4d ("Lists of CPG clocks generated from CPGMA1"), the RSwitch2 and PCI Express clock is generated from PLL5 by dividing by two, followed by the RSW2 divider. As PLL5 runs at 3200 MHz, and RSW2 is fixed to 320 MHz, the RSW2 divider must be 5. Correct the parent and the fixed divider.
