[v3,0/6] pinctrl: s32: driver improvements and generic struct use

Message

Hello,

This patch series contains some improvements for s32 pinctrl drivers suggested
by upstream[1], such as
  - Fix error shadowings and improve return value handlings.
  - Fix print format.
  - Remove unnecessary blanks.
  - Use proper macros and helpers to simplify codes.
  - Refactor config param parsing and remove config arguments that are never used.
  - Use generic struct pingroup and struct pinfunction to describe pin data.

Regards,
Chester

Changes in v3:
- Remove unnecessary type casting and correct type qualifiers.
- Split the previous generic-struct patch [v2 4/4] into two separate patches.
- Add a new patch [v3 6/6] to attach a real const .data with of_device_id.

Changes in v2:
- Link: https://lore.kernel.org/lkml/[e-mail]/
- Use of_device_get_match_data() to get matched of_device_id data.
- Enhance sizeof() arguments.
- Fix blanks and remove unnecessary parentheses.
- Drop unnecessary marcos and s32_pin_config() implemented in v1 and set/clear
  mask/config values transparently.
- Put pull-function related cases together in s32_pin_set_pull().
- Simply use generic 'struct pinfunction' rather than having extra 'struct
  s32_pmx_func'.
