Subject: [PATCH] dt-bindings: display/msm: dpu-sdm845: add missing DPU opp-table
Git-commit: feda34d14adf295a6311ffe00e9b89104bcda61b
Patch-mainline: v6.1-rc1
References: git-fixes

The 'display-controller' child (DPU) of Display SubSystem (MDSS) uses
opp-table, so reference it which allows restricting DPU schema to fixed
list of properties.

Fixes: 3d7a0dd8f39b ("dt-bindings: msm: disp: add yaml schemas for DPU bindings")
