Is anyone else having DSS failures on the 5.7 stable branch using an
omap3 board?
I haven't had time to bisect yet, but before I do I thought I'd ask.

Thanks for any suggestions. I'll bisect when I have more time.

Sounds this might be caused by some panel related between v5.6 and v5.7,
so adding Laurent to Cc.
We also started dropping legacy platform data for some SoCs, but that
should not affect omap3 so far.

I think this is caused by the panel driver not setting the connector
type. Only the panel-simple driver should be affected, fixing this
should just be a matter of setting
.connector_type = DRM_MODE_CONNECTOR_DPI
for the appropriate panel_desc entry.

Yes. I sent one fix a few days back:

The GTA04 omapdss is running on dm3730 and OpenPandora with omap3530.
But I also have a problem on omap5 (not yet analysed in any way...).

Both omap3 based devices mentioned above use special panel drivers.

I have another panel in panel-simple where .connector_type is not set.
(Haven't tested yet but would assume it fails as well).
I wonder why it was not a bulk change for all panel_desc there if it is
that important.
BR and thanks for pointing out a solution,

I tested Tomi's patch and it fixes the issue with one screen. I
updated a different panel that we use at Logic PD to enable the same
flag on a different panel. That also fixed the issue on the second
LCD.
I don't know if we can do a bulk set or not. I am not sure if all the
screens need the DPI flag.
