[PATCH v3 04/11] dt-bindings: pinctrl: apple,pinctrl: Add power-domains property

From: Hector Martin <hidden>
Date: 2021-11-24 07:35:06
Also in: linux-arm-kernel, linux-pm, linux-samsung-soc, linux-serial, lkml
Subsystem: arm/apple machine support, open firmware and flattened device tree bindings, pin control subsystem, the rest · Maintainers: Sven Peter, Janne Grunau, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Walleij, Linus Torvalds

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.
