This change enables DP controllers, DPTX0 and DPTX1 alongside
their corresponding PHYs of mdss1 which corresponds to edp2
and edp3.

This is really long and scattered across multiple people, effectively
making it a chaos for tracking. Could you please coordinate with Mani
who submitted the changes for the SoC as well as the ride board to
send these patches together?

Sure, I’ve coordinated with Mani. This will be addressed in the next
revision of the dependent patch series: https://lore.kernel.org/all/20260226111322.250176-1-quic_mkuntuma@quicinc.com/

Please do not use "This commit/patch/change", but imperative mood. See

Why do you have so many dependencies? Why isn't this merged there?
Was this patch tested (see internal testing guideline) prior to posting?
Best regards,
