Hi, Ayushi. I think this series had been verified to work. Do you have
any idea in my case? According to the public information, SA8775P is
equipped with Adreno DPU1199, SA8295P(almost identical to SC8280XP) too.
And SC8280XP has the same dsi version and dsi phy. And my device tree
nodes for the DSI0 and DSI1 are almost same as yours. I got
`dsi_err_worker: status=4` only with a blanking screen.

Best wishes,
Pengyu
