Hi, Maxime,

according to MIPI DSI spec chapter 8.8.2  the EoTp packet can be enabled 
or disabled on the protocol level.
It seems like that it might be required for the panel I am working on 
(Himax HX8379A-based panel).
Here is some crappy driver I found on github showing that it might be an 
issue  [1]

May I ask you if this feature supported by sun6i MIPI DSI driver and 
where ?
As there is no datasheet available, could you please help to support 
this feature (if not yet) ?

The second point is that the panel requires NON-BURST-WITH-SYNC-EVENTS 
mode.
Could it be a problem with the current driver?

Thank you,
