MLK-18789-1: drm/panel: Add driver for Seiko 43WVF1G panel
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.
