Merge tag 'intel-pinctrl-v5.18-1' of... 

Merge tag 'intel-pinctrl-v5.18-1' of gitolite.kernel.org:pub/scm/linux/kernel/git/pinctrl/intel into devel

intel-pinctrl for v5.18-1

* Introduce support for Alder Lake-N (required to revert misplaced ID)
* Add support for Raptor Lake-S
* Add support for Ice Lake-N (MacBookPro16,2)
* Miscellaneous fixes

The following is an automated git shortlog grouped by driver:

alderlake:
 -  Add Intel Alder Lake-N pin controller support
 -  Add Raptor Lake-S ACPI ID

baytrail:
 -  Clear direct_irq_en flag on broken configs

icelake:
 -  Add Ice Lake-N PCH pin controller support

intel:
 -  Fix a glitch when updating IRQ flags on a preconfigured line
 -  fix unexpected interrupt

Place correctly CONFIG_PINCTRL_ST in the Makefile:
 - Place correctly CONFIG_PINCTRL_ST in the Makefile

tigerlake:
 -  Revert "Add Alder Lake-M ACPI ID"
