i.MX instead of IMX ? Please be sure to use the branding consistently across Kconfig entries and various text fields.

Is this really supposed to be available for all iMX9* or is this limited to iMX95 ?

This Say Y stuff goes ...
This provides a simple pinctrl driver for i.MX SoC which supportsSCMI. This feature depends on device tree configuration. This driveris different from the linux one, this is a simple implementation,only parses the 'fsl,pins' property and configure relatedregisters.

I have posted a couple of pinctrl patches to [1] , that should simplify this pinctrl implementation. The entire series is also available in [2] , the updated mx95 pinctrl patch on top of it is [3] .
