pinctrl: s32cc: Use generic struct data to describe pin function

2023-03-27T21:36:18+00:00

Replace struct s32_pmx_func with generic struct pinfunction since they
have the same data fields.

pinctrl: s32cc: refactor pin config parsing

2023-03-27T21:35:00+00:00

Move common codes into smaller inline functions and remove argument checks
that are not actually used by pull up/down bits in the S32 MSCR register.

pinctrl: s32: refine error/return/config checks and simplify driver codes

2023-03-27T21:34:24+00:00

Improve error/return code handlings and config checks in order to have
better reliability and simplify driver codes such as removing/changing
improper macros, blanks, print formats and helper calls.

pinctrl: s32cc: fix !CONFIG_PM_SLEEP build error

2023-03-13T10:19:39+00:00

The declaration of s32_pinctrl_suspend/s32_pinctrl_resume is hidden
in an #ifdef, causing a compilation failure when CONFIG_PM_SLEEP is
disabled:

drivers/pinctrl/nxp/pinctrl-s32g2.c:754:38: error: 's32_pinctrl_suspend' undeclared here (not in a function); did you mean 's32_pinctrl_probe'?
drivers/pinctrl/nxp/pinctrl-s32g2.c:754:9: note: in expansion of macro 'SET_LATE_SYSTEM_SLEEP_PM_OPS'
  754 |         SET_LATE_SYSTEM_SLEEP_PM_OPS(s32_pinctrl_suspend,
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Remove the bogus #ifdef and __maybe_unused annation on the global
functions, and instead use the proper LATE_SYSTEM_SLEEP_PM_OPS()
macro to pick set the function pointer.

As the function definition is still in the #ifdef block, this leads
to the correct code in all configurations.

pinctrl: add NXP S32 SoC family support

2023-03-06T13:27:15+00:00

Add the pinctrl driver for NXP S32 SoC family. This driver is mainly based
on NXP's downstream implementation on nxp-auto-linux repo[1].
