Hi all,
This series adds support for the partial display mode to the Sitronix
ST7789V panel driver. This is useful for panels that are partially
occluded by design, such as the Jasonic JT240MHQS-HWT-EK-E3. Support
for this particular panel is added as well.
Note: This series is already based on

I understand Maxime's arguments, but by looking closely at the code,
this doesn't look like an hack at all and uses capabilities of the
panel controller to expose a smaller area without depending on any
changes or hacks on the display controller side which is coherent.
Following's Daniel's summary we cannot compare it to TV overscan
because overscan is only on *some* displays, we can still get 100%
of the picture from the signal.
While here, we cannot, there's physically less pixels on the panel.
If there's no more still a strong nack or pending comments,
I plan to apply those tomorrow.
Thanks,
Neil
Looking forward to your comments!
