[00/14] pinctrl: renesas: Add support for R-Car V4M

Hi all,

This patch series adds pin control support for the R-Car V4M (R8A779H0)
SoC.

Some, but not all, of this has been tested on the Gray Hawk Single
development board.

There are also a few unresolved questions:
  - According to the documentation, using I2C requires setting
    SEL_S{CL,DA}[0-3]_1 instead of SEL_S{CL,DA}[0-3]_0 in the MOD_SEL
    register.  However, I2C works regardless of this setting, just like
    on R-Car V4H (see commit 42cbd16e7c547499 ("pinctrl: renesas:
    r8a779g0: Fixup MODSEL8")),
  - Using i2c-gpio instead of i2c-rcar for I2C0 does not work, even
    when using a similar scheme like on R-Car S4 and V3U (see e.g.
    commit 8bdd369dba7ff2f8 ("pinctrl: renesas: r8a779f0: Fix GPIO
    function on I2C-capable pins").

For testing, I have updated [1] accordingly.
Thanks for your comments!

Thanks, queuing in renesas-pinctrl for v6.9.
