Subject: sun6i MIPI DSI driver EoTp
Date: Mon, 11 Mar 2019 21:43:36 +0300 [thread overview]
Message-ID: <ff953218-219e-7f92-476d-91e2b9904776@orpaltech.com> (raw)
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,
