10   - Liu Ying <victor.liu@nxp.com>
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
21   The i.MX8qm/qxp Display Pixel Link is accessed via System Controller Unit(SCU)
