4b2b869e8e drm/panel: mantix: Support panel from Shenzhen Yashi Changhua Intelligent Technology Co
The panel uses the same driver IC and has the same resolution but a
slightly different default mode. It seems it can work with the same
init sequence.

dd396dbc4d drm/panel: mantix: Tweak init sequence
We've seen some (non permanent) burn in and bad white balance
on some of the panels. Adding this bit from a vendor supplied
sequence fixes it.

787099f867 drm/panel: mantix: Fix panel reset
The mantix panel needs two reset lines (RESX and TP_RSTN) deasserted to
output an image. Only deasserting RESX is not enough and the display
will stay blank. Deassert in prepare() and assert in unprepare() to keep
device held in reset when off.
