   14   This panel driver is a component that acts as an intermediary
   15   between an RGB output and a variety of panels. The panel
   16   driver is strapped up in electronics to the desired resolution
   17   and other properties, and has a control interface over 3WIRE
   18   SPI. By talking to the TPG110 over SPI, the strapped properties
   19   can be discovered and the hardware is therefore mostly
   20   self-describing.
   21 
   22          +--------+
   23   SPI -> |  TPO   | -> physical display
   24   RGB -> | TPG110 |
   25          +--------+
   26 
   27   If some electrical strap or alternate resolution is desired,
   28   this can be set up by taking software control of the display
   29   over the SPI interface. The interface can also adjust
   30   for properties of the display such as gamma correction and
   31   certain electrical driving levels.
   32 
   33   The TPG110 does not know the physical dimensions of the panel
   34   connected, so this needs to be specified in the device tree.
   35 
   36   It requires a GPIO line for control of its reset line.
   37 
   38   The serial protocol has line names that resemble I2C but the
   39   protocol is not I2C but 3WIRE SPI.
