[PATCH/RFC] pinctrl: renesas: r8a779g0: Add INTC-EX pins, groups, and function

Commit Message

Geert Uytterhoeven Sept. 28, 2022, 12:35 p.m. UTC

Add pins, groups, and function for the Interrupt Controller for External
Devices (INTC-EX) on the Renesas R-Car V4H (R8A779G0) SoC.

Signed-off-by: Geert Uytterhoeven <[e-mail]>

The naming of alternate pins is inconsistent, but it does match the
current documentation (R-Car V4H rev. 0.51), e.g.:
  - IRQ0 and IRQ0_A,
  - IRQ3 and IRQ3_B,
  - IRQ4_A and IRQ4_B.
Perhaps this has been improved in a later revision?
