Hi All,
This patch series aims to add PFC (Pin Function Controller) support for
Renesas RZ/V2H(P) SoC. The PFC block on RZ/V2H(P) is almost similar to
one found on the RZ/G2L family with couple of differences. To able to
re-use the use the existing driver for RZ/V2H(P) SoC function pointers
are introduced based on the SoC changes.
v2->v3
- Dropped patch 1/13 [0] as its been already queued up.
- Updated description for renesas,output-impedance property
- Added three new patches 02/15, 04/15 and 14/15
- Updated size for cfg in struct rzg2l_variable_pin_cfg
- Included RB tags
- Introduced single function pointer to (un)lock PFC
- Now passing offset to pmc_writeb() instead of virtual address
- Renamed read_oen->oen_read
- Renamed write_oen->oen_write
- Renamed get_bias_param -> hw_to_bias_param
- Renamed get_bias_val -> bias_param_to_hw
- Dropped un-necessary block {}
- Now reading arg before calling hw_to_bias_param()
- Added gaurd for custom_conf_items in struct rzg2l_pinctrl_data
- 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
- Fixed review comments pointed by Rob
- Incorporated changes suggested by Claudiu
- Fixed build error reported for m68K
- Dropped IOLH groups as we will be passing register values
- Fixed configs for dedicated pins
- Added support for slew-rate and bias settings
- Added support for OEN
