Applying: dt-bindings: msm/dp: add data-lanes and link-frequencies property
.git/rebase-apply/patch:47: trailing whitespace.

.git/rebase-apply/patch:51: trailing whitespace.


Also the dt_binding_check fails with an error for this schema. And after 
fixing the error in the schema I faced an example validation error. Did 
you check that the schema is correct and that the example validates 
against the schema?

PLease add empty lines between the property definitions

This is already a part of video-interfaces, so you don't need $ref

enum: [0, 1, 2, 3]

I think we can have enum here too.
