Hi Rob,
I missed adding "robh+dt@kernel.org" earlier in this thread.
Please check my response to your review comments. Regarding your
suggestion to use <vendor>,<soc>-<block> format for compatible property,
should I also upload a new patch to make changes in 10nm, 14nm, 20nm,
and 28nm DSI PHY DT bindings?
Thanks,
Rajeev
