Merge tag 'pinctrl-v6.5-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control fixes from Linus Walleij:
 "Fixes two issues with the Qualcomm SA8775P platform:

   - Some minor device tree binding flunky that is nice to iron out but
     more importantly:

   - Support the increased interrupt targets mask from 3 to 4 bits,
     making interrupts with higher (hardware) numbers work"

* tag 'pinctrl-v6.5-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
  pinctrl: qcom: Add intr_target_width field to support increased number of interrupt targets
  dt-bindings: pinctrl: qcom,sa8775p-tlmm: add gpio function constant
