Add a panel database to the driver instead of reading propertes from DT
data. This is similar to panel-simple, and I believe it's more future
safe way to handle the panels.

The DSI version of the panel behaved instable and close
scrutiny of the vendor driver from the Samsung

the DSI mode panel than the DPI mode panel.
Make the initialization depend on whether we are in
DSI or DPI mode and handle the differences.
After this the panel on the GT-I8190 becomes much more
stable.
Also spell out some more custom DCS commands found in
the vendor source code to cut down a bit on magic
where we can.

Add support for the BOE NV110WTM-N61 panel. The EDID lists two modes
(one for 60 Hz refresh rate and one for 40 Hz), so we'll list both of
them here.
Note that the panel datasheet requires 80 ms between HPD asserting and
the backlight power being turned on. We'll use the new timing
constraints structure to do this cleanly. This assumes that the
backlight will be enabled _after_ the panel enable finishes. This is
how it works today and seems a sane assumption.

On the panel I'm looking at, there's an 80 ms minimum time between HPD
being asserted by the panel and setting the backlight enable GPIO.
While we could just add an 80 ms "enable" delay, this is not ideal.
Link training is allowed to happen in parallel with this delay so the
fixed 80 ms delay over-delays.
We'll support this by logging the time at the end of prepare and then
delaying in enable if enough time hasn't passed.

It is believed that all of the current users of the "unprepare" delay
don't actually need to wait the amount of time specified directly in
the unprepare phase. The purpose of the delay that's specified is to
allow the panel to fully power off so that we don't try to power it
back on before it's managed to full power down.
Let's use this observation to avoid the fixed delay that we currently
have. Instead of delaying, we'll note the current time when the
unprepare happens. If someone then tries to prepare the panel later
and not enough time has passed, we'll do the delay before starting the
prepare phase.

The probe routine acquires the reset GPIO using GPIOD_OUT_LOW. Directly
afterwards it calls acx565akm_detect(), which sets the GPIO value to
HIGH. If the bootloader initialized the GPIO to HIGH before the probe
routine was called, there is only a very short time period of a few
instructions where the reset signal is LOW. Exact time depends on
compiler optimizations, kernel configuration and alignment of the stars,
but I expect it to be always way less than 10us. There are no public
datasheets for the panel, but acx565akm_power_on() has a comment with
timings and reset period should be at least 10us. So this potentially
brings the panel into a half-reset state.
The result is, that panel may not work after boot and can get into a
working state by re-enabling it (e.g. by blanking + unblanking), since
that does a clean reset cycle. This bug has recently been hit by Ivaylo
Dimitrov, but there are some older reports which are probably the same
bug. At least Tony Lindgren, Peter Ujfalusi and Jarkko Nikula have
experienced it in 2017 describing the blank/unblank procedure as
possible workaround.
Note, that the bug really goes back in time. It has originally been
introduced in the predecessor of the omapfb driver in commit 3c45d05be3
("OMAPDSS: acx565akm panel: handle gpios in panel driver") in 2012.
That driver eventually got replaced by a newer one, which had the bug
from the beginning in commit 84192742d9 ("OMAPDSS: Add Sony ACX565AKM
panel driver") and still exists in fbdev world. That driver has later
been copied to omapdrm and then was used as a basis for this driver.
Last but not least the omapdrm specific driver has been removed in
commit 45f16c82db ("drm/omap: displays: Remove unused panel drivers").

The init sequence consist of a number of unknown settings
for the display controller. This patch achieves two things:
- Fix an error that must have happened when the driver was
converted from the backlight subsystem: the 0xb8
configuration command was lost and added as a tail to
the previous command.
- Update some minor settings in some bytes here and there
according to changes in the Samsung GT-I9070 and
Samsung GT-S7710 code dumps. Since two other devices use
these settings they probably reflect trimmings later
found to be better for the display rather than
customizations for these devices.

Copy over the width/height in millimeters to the

bus format and bus flags for the display.
When used as DPI this display requires DE to be
active low and pixel data to be output on the
negative edge. It might be that it was previously
used with a display controller that either does
not support these settings or was hardcoded to use
these as default. This information comes from the

The OnePlus 6/T devices use different panels however they are
functionally identical with the only differences being the resolution.
The panels also don't seem to be used by any other devices, just combine
them into one driver.
The panels are: samsung,sofef00
and samsung,s6e3fc2x01

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.

It provides a MIPI DSI interface to the host, a built-in LED backlight
and touch controller.
