[PATCH v3 02/10] dt-bindings: display/msm/gmu: Allow passing QMP handle

From: Konrad Dybcio
Date: Wed Aug 23 2023 - 08:56:13 EST


When booting the GMU, the QMP mailbox should be pinged about some tunables
(e.g. adaptive clock distribution state). To achieve that, a reference to
it is necessary. Allow it and require it with A730.
