[PATCH 05/10] dt-bindings: display/msm: Add Qualcomm SAR2130P
Dmitry Baryshkov

Sat Mar 8 01:42:23 UTC 2025
From: Dmitry Baryshkov <dmitry.baryshkov at linaro.org>
Describe the Mobile Display SubSystem (MDSS) device present on the
Qualcomm SAR2130P platform. It looks pretty close to SM8550 on the
system level. SAR2130P features two DSI hosts and single DisplayPort
controller.
