From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>
Add pinctrl driver support for RZ/V2H(P) SoC.
Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>
---
v2->v3
- Renamed PIN_CFG_OPEN_DRAIN->PIN_CFG_NOD
- Renamed PIN_CFG_SCHMIT_CTRL->PIN_CFG_SMT
- Introduced PWPR_REGWE_A instead of using PWPR_PFCWE
- Dropped using pwpr_lock
- Optimized rzv2h_pin_to_oen_bit()
RFC->v2
- Renamed renesas-rzv2h,output-impedance -> renesas,output-impedance
- Dropped IOLH groups
- Fixed dedicated pin configs
- Updated r9a09g057_variable_pin_cfg
- Added support OEN
- Added support for bias settings
- Added function pointers for pwpr (un)lock
- Added support for slew-rate
