13  The Freescale i.MX8qxp Pixel Link to Display Pixel Interface(PXL2DPI)
14  interfaces the pixel link 36-bit data output and the DSI controller’s
15  MIPI-DPI 24-bit data input, and inputs of LVDS Display Bridge(LDB) module
16  used in LVDS mode, to remap the pixel color codings between those modules.
17  This module is purely combinatorial.
18
19  The i.MX8qxp PXL2DPI is controlled by Control and Status Registers(CSR) module.
20  The CSR module, as a system controller, contains the PXL2DPI's configuration
21  register.
