Signed-off-by: Lad Prabhakar Reviewed-by: Geert Uytterhoeven --- 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 ---
