[PATCH v3 03/11] dt-bindings: iommu: apple,dart: Add power-domains property
From: Hector Martin <hidden>
Date: 2021-11-24 07:34:56
Also in:
linux-arm-kernel, linux-pm, linux-samsung-soc, linux-serial, lkml
Subsystem:
arm/apple machine support, iommu subsystem, open firmware and flattened device tree bindings, the rest · Maintainers:
Sven Peter, Janne Grunau, Joerg Roedel, Will Deacon, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
This will bind to the PMGR pwrstate nodes that control power/clock gating to SoC blocks. The DART driver doesn't do runtime-pm yet, so initially this will just keep the domain on permanently.
