This driver communicates with the Atmel microcontroller for sequencing
the poweron of the TC358762 DSI-DPI bridge and controlling the
backlight PWM.
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.
v6: Drop unused brightness #define (noticed by Thierry)

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.
Based on initial patch submission from Breno Lima.
