2024-07-30clk: renesas: rcar-gen4: Remove unused default PLL2/3/4/6 configsGeert Uytterhoeven1-5/+5
The default PLL2/3/4/6 multiplier and divider configurations are no longer used after the conversion to fixed or variable fractional PLL clock types. Note that the default configurations are still documented in the comments above the individual rcar_gen4_cpg_pll_config instances.

2024-07-30clk: renesas: r8a779g0: Model PLL1/3/4/6 as fractional PLLsGeert Uytterhoeven1-7/+7
Currently, all PLLs but PLL2 are modelled as fixed divider clocks, based on the state of the mode pins. However, the boot loader stack may have changed the actual PLL configuration from the default, leading to incorrect clock frequencies. Describe PLL1 as a fixed fractional PLL instead, and PLL2, PLL3, PLL4, and PLL6 as variable fractional PLLs. Reformat nearby lines to retain a consistent layout.

2023-01-24clk: renesas: r8a779g0: Add custom clock for PLL2Geert Uytterhoeven1-7/+7
Currently the PLLs are modeled as fixed factor clocks, based on initial settings. However, enabling CPU boost clock rates requires increasing the PLL clock rates. Add a custom clock driver to model the PLL clocks on R-Car Gen4, and use it for PLL2 on R-Car V4H. This allows the Z clock (Cortex-A76 core clock) to request PLL rate changes, and enable boost mode for the High Performance mode. For now this is limited to integer multiplication modes. Note that the definition for CPG_PLLxCR0_NI uses the value for R-Car V4H. On R-Car S4-8, the integer and fractional multiplication fields are one bit larger resp. smaller, but R-Car S4-8 does not support High Performance mode.
