7 title: Freescale i.MX8qm/qxp Display Pixel Link
13 The Freescale i.MX8qm/qxp Display Pixel Link(DPL) forms a standard
14 asynchronous linkage between pixel sources(display controller or
15 camera module) and pixel consumers(imaging or displays).
16 It consists of two distinct functions, a pixel transfer function and a
17 control interface. Multiple pixel channels can exist per one control channel.
18 This binding documentation is only for pixel links whose pixel sources are
