2022-04-13clk: renesas: Move RPC core clocksGeert Uytterhoeven1-5/+4
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.

On some R-Car Gen3 SoCs (e.g. R-Car D3), PLL1 and PLL3 use a divider value different from one. Extend struct rcar_gen3_cpg_pll_config to handle this. As all multipliers and dividers are small, table size increase can be kept limited by storing them in u8s instead of unsigned ints, which saves ca. 0.5 KiB for a generic kernel.

The Clock Pulse Generator / Module Standby and Software Reset module in R-Car H3 ES2.0 differs from ES1.x in the following areas: - More core clocks (S0D2, S0D3, S0D6, S0D8, S0D12), - Different parent clocks for AUDMAC, EtherAVB, FCP, FDP, IMR, SYS-DMAC, VIN, VSPB, VSPI, - Removal of modules CSI21, FCPCI, FCPF2, FCPVD3, FCPVI2, FDP1-2, USB3-IF1, VSPD3, VSPI2, - Addition of modules EHCI3, HS-USB-IF3, USB-DMAC3-0, USB-DMAC3-1. The goal is twofold: 1. Support both the ES1.x and ES2.0 SoC revisions in a single binary for now, 2. Make it clear which code supports ES1.x, so it can easily be identified and removed later, when production SoCs are deemed ubiquitous. This is achieved by: - Updating the clock tables for the latest revision (ES2.0), but not removing clocks that only exist on earlier revisions (ES1.x), - Detecting the SoC revision at runtime using the new soc_device_match() API, and fixing up the clocks tables to match the actual SoC revision, by: - NULLifying core and module clocks of modules that do not exist, - Reparenting module clocks that have a different parent on ES1.x.

According to the datasheet, SDn clocks are from the SDSRC clock. And the SDSRC has a 1/2 divider. So, we should have ".sdsrc" as an internal core clock. Otherwise, since the sdhi driver will calculate clock for a sd card using the wrong parent clock rate, and then performance will be not good.

2016-06-21clk: renesas: r8a7795: Correct lvds clock parentGeert Uytterhoeven1-1/+1
According to the latest information, the parent clock of the LVDS module clock is the S0D4 clock, not the S2D1 clock. Note that this change has no influence on actual operation, as the rcar-du LVDS encoder driver doesn't use the parent clock's rate.

Extract the code to support parts common to all members of the R-Car Gen3 SoC family into a separate file, to ease sharing among SoC-specific drivers. Note that while the cpg_pll_configs[] arrays and the selection of the config based on the MODE bits are identical on R-Car H3 and R-Car M3-W, they are not common, and may be different on other R-Car Gen3 SoCs.
