Subject: [PATCH v2 0/4] drm/tinydrm: new dirver for ILI9341 displays

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)

Subject: [PATCH v2 4/4] drm/tinydrm: new driver for ILI9341 display panels

This adds a new driver for display panels that use the Ilitek ILI9341
controller. It currently supports a single display panel, namely
the YX240QV29-T (e.g. Adafruit 2.4" TFT).

The init sequence is from the Adafruit Python library for the ILI9341
controller. https://github.com/adafruit/Adafruit_Python_ILI9341

Subject: [PATCH v2 3/4] dt-bindings: new binding for Ilitek ILI9341 display panels

This adds a new binding for Ilitek ILI9341 display panels. It includes
a compatible string for one display (more can be added in the future).

The vendor prefix "noname" is used because the vendor is not known.
The YX240QV29-T panel[1] is found, for example, in an Adafruit breakout
board[2] and in Mindsensors' PiStorms[3].

Looks like I forgot to update "noname" to "adafruit" in the commit message.
Patch is as intended though.
