[PATCH v6 01/16] dt-bindings: clock: qcom,qcm2290-dispcc: Add missing power-domains property
From: Imran Shaik
Date: Sat Jul 18 2026 - 08:57:11 EST
Add the missing power-domains property to associate DISPCC with RPMPD_CX.
This is to ensure the genpd performance state votes on the GDSC to get
propagated to the CX rail and to avoid the rail under-voltage conditions.
This change breaks ABI, as the power-domains property is marked as
required.
Fixes: 85cedb4e0c9d ("dt-bindings: clock: Add qualcomm QCM2290 DISPCC bindings")
