Subject: dt-bindings: pinctrl: apple,pinctrl: Add power-domains property
X-Git-Tag: v5.17-rc1~201^2~32^2~8

dt-bindings: pinctrl: apple,pinctrl: Add power-domains property

This will bind to the PMGR pwrstate nodes that control power/clock
gating to SoC blocks. The pinctrl driver doesn't do runtime-pm yet, so
initially this will just keep the domain on permanently.
