From b0c4f44b87e4011034e4cb60dc93477f765ff42e Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Thu, 20 Feb 2025 19:58:09 +0100 Subject: [PATCH] dt-bindings: power: rockchip: add regulator support Add optional support for a voltage supply required to enable a power domain. The binding follows the way it is handled by the Mediatek binding to keep things consistent. This will initially be used by the RK3588 GPU power domain, which fails to be enabled when the GPU regulator is not enabled. It is not limited to that platform, since older generations have similar requirements. They worked around this by marking the regulators as always-on instead of describing the dependency.
