Current Mediatek DRM driver does not support interlaced mode, and
will hang if such resolution is used: Filter those to prevent
kernel hangs, until the DRM driver is fixed properly.

You probably want to check out Jose's mode_valid work, since only
filtering in the connector's ->mode_valid callback isn't enough. You also
need to filter in ->mode_fixup (or some other place called at atomic_check
time).

Hi, Daniel:

Yes, I still need to filter in ->mode_fixup.

Hi, Bibby:

Because Jose's work plan to use mode_valid to replace mode_fixup, so
it's better to refine this patch after Jose's work is done. And I would
now remove this patch from my branch.

Btw if you have a revised version of your patch on top of Jose's series, a
tested-by on that would be awesome. The more people find it useful, the
faster it will land.

Hi, Daniel:

I understand.

Hi Bibby:

If you have time, please help to test Jose's patches with the problem
you have met. Otherwise, it would be a long process.
