Just use ilitek then. I would do "ilitek,ili9225-2.2in-176x220" and hopefully there aren't others that size. I'm guessing you would have found them if so. Otherwise, looks fine. > An example of this nameless device can be found at: > https://github.com/Nkawu/TFT_22_ILI9225 > > Signed-off-by: David Lechner <david@lechnology.com> > --- > .../devicetree/bindings/display/ilitek,ili9225.txt | 25 ++++++++++++++++++++++ > 1 file changed, 25 insertions(+) > create mode 100644 Documentation/devicetree/bindings/display/ilitek,ili9225.txt

This adds a new binding for display panels that use an Ilitek ILI9225 controller. The "generic,2.2in-176x220-ili9225-tft" device listed has no identification markings whatsoever and an hour of googling turned up nothing, hence the use of "generic".
