From 364609125e2ca745c698ec157615ff179b239344 Mon Sep 17 00:00:00 2001 From: Hector Martin Date: Wed, 24 Nov 2021 15:13:15 +0900 Subject: [PATCH] dt-bindings: iommu: apple,dart: Add power-domains property 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.
