Got it, we will update more descriptions in the next version.
There is no transfer/interrupt function in the upstream DSI driver.
We also implement the following function [1][2] in this patch series.

Original flow works on there is a bridge chip: DSI -> bridge -> panel.
In this case: DSI -> panel, the DSI sub driver flow should be updated.
We need to initialize DSI first so that we can send commands to panel.
