Thanks, I think I missed this in the diff when importing the updated DT
bindings into this example.

Will drop for v3 pending other comments.

More importantly, why is your bot complaining the following about this
example:

['qcom,sm6125-dsi-ctrl', 'qcom,mdss-dsi-ctrl'] is too long
...
'qcom,sm6125-dsi-ctrl' is not one of ['qcom,dsi-ctrl-6g-qcm2290', 'qcom,mdss-dsi-ctrl']

This is patch 07/15, but that compatible was already added in 05/15.
