[RFC,0/7] Add mipi dsi command mode support.

Message

Kulkarni, Vandita Oct. 14, 2019, 11:01 a.m. UTC

This series has mainly patches to configure the dsi in
command mode, TE event handling and initiate a frame
request to the panel. Floating the RFC for review wrt
the above mentioned implementation.
For now we are configuring the MIPI DSI to operate in
TE gate mode and take TE events via GPIO.

There are few places that needs to be fixed to handle,
cases where mpi dsi could be operating in single link
cmd mode on port B.

I have tested dual link with this series on icl-y.
There is one open wrt flipdone which needs to be fixed.
This is WIP.
