This is based on v4 of Dmitry's work on multiple DSI interfaces:
https://lore.kernel.org/linux-arm-msm/20210717124016.316020-1-dmitry.baryshkov@xxxxxxxxxx/
With that in place add SC8180x DP and eDP controllers.
Thanks for posting the changes.
I dont have major concerns on the series as such apart from minor
comments which i will post in a day or two
but I will check and get back if this has been validated on sc7280
without any concerns.
One question i had is not directly related to this series but related to
multi-DP in general.
Does audio work fine across both the DPs when both are connected?
The reason I ask this question is that, I dont know how two hdmi-codec
instances are handled today.
So we will register twice with hdmi-codec so there should be two audio
streams.
But I am not sure if this works correctly in todays design with
hdmi-codec.
Any chance you had validated this?
