From: Li Liu <quic_lliu6@xxxxxxxxxxx>

Add display MDSS and DSI configuration for QCS615 RIDE board.
QCS615 has a DP port, and DP support will be added in a later patch.

Use IRQ flags instead of just 0 (here and further on). Also it might be
better to use interrupts-extended instead.
Got it, will use interrupts-extended instead

Add empty line before device nodes (here and furher on).
Sorry, will add it in next patch.

Yes, much better. BTW: are you sure that it's really IRQ_TYPE_NONE?
We extensively tested FALLING and BOTH type, and they all work. However, I believe it’s better to use the default type, which is the same as the downstream approach. This way, it will be more stable.
