Hi Marek,

Hi,

Actually this property is specific also to DSI8x bridge, as you can see
from the screenshot below taken from official datasheet:

And it's the sn65dsi8x driver that tells MIPI driver which flags to use
during attachment.

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.

So, for example, this bridge can work also for MIPI interfaces which don't
support burst-mode.
Also, as a value-added benefit, I found non-burst mode better for some
1920x1200 LVDS panels I'm testing (Of course with more energy consumption).
That's why I though it could be useful have this option, since SN65DSI8x
supports both modes.

Can you share which panel model this is ?
