This series adds a new tinydrm driver for the Ilitek ILI9341 controller and
a 2.4" display panel that uses this controller.
A few things to note here:
* The datasheet for this display[1] doesn't have a vendor mentioned on it
anywhere, so I have used "adafruit" as the vendor prefix. If someone has a
better suggestion, please speak up.
* The MAINTAINERS patch for ili9225 is included so we don't end up with a merge
conflict later on.
v2 changes:
* change vendor prefix from "noname" to "adafruit"
* new patch for "adafruit" vendor prefix
* minor style changes
* drop regulator from driver (instead of adding to DT bindings)
