Merge tag 'clk-renesas-for-v4.10-tag2' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers into clk-next

Pull Renesas clk driver updates from Geerty Uytterhoeven:

- Add R-Car RST driver for obtaining mode pin state, and move the
related functionality from platform code to DT,
- Add r8a7743 and r8a7745 CPG Core Clock Definitions.

The commits here are intermingled with arm-soc material because
of the hard dependency we're breaking between mach code and
driver code. We're replacing that with a driver dependency
between the soc driver and the clk driver.

soc: renesas: Add R-Car RST driver

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.
