until it fails - once it's failed you can get it to come back by running the sequence of commands again a few times.
Ah, ok. Haven't tried that ever on the Pyra :)
Maybe because I had trouble waking up my HDMI-Monitor when running Letux kernel on the RasPi 3B+. So I thought that the command is somehow broken.
Note that this is with the OMAP5 X11 driver - https://dev.pyra-handheld.com/packages/xserver-xorg-video-armsoc-omap5
I can't see a particularly concerning difference between our disable function (which is where the problems seem to start) and other panel drivers. I half wonder if the problem might be in the OMAP DSI stuff rather than the panel driver.
Yes, it is unlikely a problem of the panel driver (which follows structure of the otm8009a driver which is used by some STM mipi dsi host). As said Tomi was not sure about the OMAPDRM driver doing all sequencing correctly.
So let's wait until the new OMAPDRM subsystem arrives in linux-next and then submit fixes we can also backport to our letux-5.10.y series.
I haven't had time to look at any OMAP stuff lately. Are things still broken?
Also, unfortunately my old OMAP5 uevm + a nonsupported DSI videomode panel is not working anymore at all (it was slightly broken already before but sometimes worked), so I don't have any DSI videomode device.
