Say Y here if you want to enable support for the IPS-LCD panel
|

module for HTC One X. Driver supports a family of panels,
|
||||
made at least by 3 vendors (Sharp, Sony and AUO), but set up
|
||||
using the same DSI command sequence. The panel has a 720x1280
|

resolution and uses 24 bit RGB per pixel.
