The commit c87d1c4b5b9a ("drm/mediatek: dsi: Use symbolized register
definition") inverted the logic of the control bit. Maybe it was because
of the bad naming which was fixed in commit 0f3b68b66a6d ("drm/dsi: Add
_NO_ to MIPI_DSI_* flags disabling features"). In any case, the logic
wrong and there will be no EOTp on the DSI link by default. Fix it.
Fixes: c87d1c4b5b9a ("drm/mediatek: dsi: Use symbolized register definition")

Hello Michael,
your commit is missing a small piece! :-)
Besides, I've already sent a fix for what you're trying to do here:

Cheers,

Ahh thanks, didn't noticed this. If not already applied, I'll send
a Tested-by: later.
Please disregard this patch then.
