Okay, I get it.
So if you think this mode shouldn't be implemented within this driver, we can close the thread.
Just for information, this driver has been implemented from the work done by Compulab (as it says in the driver's initial comments), and they do not put the burst mode by default, not even giving the possibility to activate it by dts:
The panels that I've had these problems with are some of JuTouch's 1920x1200, for example JT101TM015 , and I solved it by giving the option to remove this mode.
I have also heard from other colleagues who have had the same problem on some dual-channel displays.
Thank you,
Stefano

There are other bridges and panels which support both DSI burst and
sync-pulse/sync-events modes, so a property which selects the mode is
generic, not specific to this particular bridge . The bridge driver
could parse such generic property, although it would be better if the
core code parsed it instead.

Can you share which panel model this is ?
