drivers: NXP drivers not selecting PINCTRL when needed #78353

Open decsny opened 5 days ago

decsny commented 5 days ago

This is an issue for more than NXP boards and drivers, but this tracking issue is for NXP platforms only as that is what the NXP platform maintainers will commit to fixing.

The issue is that many (maybe all) NXP boards are setting CONFIG_PINCTRL=y in the board conf file. This should not have to happen because any drivers that use the pinctrl should select it automatically.

Example: https://github.com/zephyrproject-rtos/zephyr/blob/dc5f1bfb3f2eee3e3775175232d508660f5d6efe/boards/nxp/frdm_mcxn947/frdm_mcxn947_mcxn947_cpu0_defconfig#L12

The only exception I found was the twr_ke18f board which does use pinctrl APIs in the board code itself: https://github.com/zephyrproject-rtos/zephyr/blob/dc5f1bfb3f2eee3e3775175232d508660f5d6efe/boards/nxp/twr_ke18f/pinmux.c#L11-L27

The board's Kconfig file would need to select it in that case
