Now the R-Car Gen2 CPG clock driver obtains the state of the mode pins from the R-Car RST driver, there's no longer a need to pass this state explicitly. Hence we can just call of_clk_init() instead. Signed-off-by:

Now the R-Car H1 CPG clock driver obtains the state of the mode pins from the R-Car RST driver, there's no longer a need to pass this state explicitly. Hence we can just remove the .init_time() callback, the generic ARM code will take care of calling of_clk_init() and clocksource_probe(). Signed-off-by:

Add a driver for the Renesas R-Car Gen1 RESET/WDT and R-Car Gen2/Gen3 and RZ/G RST module. For now this driver just provides an API to obtain the state of the mode pins, as latched at reset time. As this is typically called from the probe function of a clock driver, which can run much earlier than any initcall, calling rcar_rst_read_mode_pins() just forces an early initialization of the driver. Despite the current simple and almost identical handling for all supported SoCs, the driver matches against SoC-specific compatible values, as the features provided by the hardware module differ a lot across the various SoC families and members.

Add DT bindings for the Renesas R-Car Reset Controller (R-Car Gen1 RESET/WDT and R-Car Gen2/Gen3 and RZ/G RST). As the features provided by the hardware module differ a lot across the various SoC families and members, only SoC-specific compatible values are defined. For now we use the RST only for providing access to the state of the mode pins, which is needed by the clock driver. Signed-off-by:
