Subject: [PATCH v3 3/5] dt-bindings: display/msm: drop
assigned-clock-parents for dp controller
From: Abhinav Kumar <quic_abhinavk@...cinc.com>
Current documentation of assigned-clock-parents for dp controller does not
describe its functionality correctly making it harder to extend it for
adding multiple streams.
Instead of fixing up the documentation, drop the assigned-clock-parents
and assigned-clocks along with the usages in the chipset specific MDSS
yaml files.
