This is part B of a 3-part CV75 split:

  A: bindings + RCT/CCU clocks + SoC/EVK DT + MAINTAINERS
  B: pinctrl + PL061 GPIO variant  (this series)
  C: 8250_dw UART quirks

Depends on series A:

Link to v3:
https://lore.kernel.org/r/20260813-cv75-v3-b-v3-0-1d82e18da09b@ambarella.com

Link to v2:
https://lore.kernel.org/r/20260806-longzhao-upstream-cv75-v2-v2-0-6b09707c5fe9@ambarella.com

Summary:
- CV75 pinctrl binding and driver
- Ambarella register-layout variant for gpio-pl061
  (DT binding and driver in separate patches) 

Changes since v3:
- Split pl061 DT binding and driver into separate patches (Bartosz)

Changes since v2 (B scope):
- reuse PL061 instead of a duplicated GPIO implementation (Linus)
- complete function/groups enums in the binding (Krzysztof)

Verified on CV75 with A+B+C.
