This issue has not been observed on revision 1, while the recovery mechanism introduces a different issue, where the END_OF_FRAME interrupt doesn't fire while drm is waiting for vblanks. On rev1: recover from sync lost errors by simply clearing the RASTER_ENABLE bit in the RASTER_CTRL register and re-enabling it again as is suggested by the datasheet.

For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment.

Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.
