2023-03-27pinctrl: s32cc: Use generic struct data to describe pin functionChester Lin2-20/+12
Replace struct s32_pmx_func with generic struct pinfunction since they have the same data fields.

2023-03-27pinctrl: s32cc: embed generic struct pingroupChester Lin2-36/+33
Use generic data structure to describe pin control groups in S32 SoC family and drop duplicated struct members.

2023-03-27pinctrl: s32cc: refactor pin config parsingChester Lin1-19/+33
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.

2023-03-27pinctrl: s32: refine error/return/config checks and simplify driver codesChester Lin2-69/+76
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.

2023-03-13pinctrl: s32cc: fix !CONFIG_PM_SLEEP build errorArnd Bergmann3-8/+5
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.
