The LTK050H3146W is 5.0" 720x1280 DSI display. There are two variants
with essentially the same name, LTK050H3146W and LTK050H3146W-A2.
They differ in their init sequence and mode details.

This adds a driver for panels based on the Novatek NT35510
display driver IC, such as the Hydis HVA40WV1 panel found
in the Samsung GT-S7710.
The NT35510 can be used with both internal and external
backlight (such as GPIO backlight) so we support both:
if no external backlight is found, we register a subdriver
for the internal backlight.

The TPO (Toppoly) TPG110 is a pretty generic display driver
similar in vein to the Ilitek 93xx devices. It is not a panel
per se but a driver used with several low-cost noname panels.
This is used on the Nomadik NHK15 combined with a OSD
OSD057VA01CT display for WVGA 800x480.
The driver is pretty minimalistic right now but can be
extended to handle non-default polarities, gamma correction
etc.
The driver is based on the baked-in code in
drivers/video/fbdev/amba-clcd-nomadik.c which will be
decomissioned once this us upstream.

This adds the appropriate dependency.
Note that while include/linux/backlight.h provides a stub inline when
backlight support is not enabled, this isn't enough to deal with the
case where backlight support is built as a module but the panel driver
is built-in, in which case linking will still fail as above.
One way to avoid this is to add a dependency such as this:
depends on BACKLIGHT_CLASS_DEVICE || BACKLIGHT_CLASS_DEVICE=n
but that is rather complex and misses the point that the panel support
is mostly useless without backlight support.

The ARM reference designs "Versatile AB" and "Versatile PB"
contain panel connectors with autodetection of the connected
panel type. This adds a small driver utilizing the MFD syscon
look-up to read the autodetection register and set up the
corresponding panel appropriately.
In the source file there is a bit of elaboration of the
panel types and interfaces on these boards.
This was tested with the PL111 DRM driver on the ARM Versatile
AB with the IB2 daughterboard.

v2: Set the same default orientation as the closed source firmware
used, which is the best for viewing angle.
v3: Rewrite as an i2c client driver after bridge driver rejection.
v4: Finish probe without the DSI host, using the new delayed
registration, and attach to the host during mipi_dsi_driver probe.
v5: Rework to drop the "probe without DSI host" mode again, now that
vc4 will create the host early on.

Add driver for Seiko Instruments Inc. 4.3" WVGA (800 x RGB x 480)
TFT with Touch-Panel.
Datasheet available at:
http://www.glyn.de/data/glyn/media/doc/43wvf1g-0.pdf
Seiko 43WVF1G panel has two power supplies: avdd and dvdd and they
require a specific power on/down sequence.
For this reason the simple panel driver cannot be used to drive this
panel, so create a new one heavily based on simple panel.
