The vendor prefix "noname" is used because the vendor is not known.


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


The YX240QV29-T panel[1] is found, for example, in an Adafruit breakout
board[2] and in Mindsensors' PiStorms[3].

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

2018-05-25 Thread David Lechner 
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].
