13   The Freescale i.MX8qm/qxp LVDS Display Bridge(LDB) has two channels.
15   The i.MX8qm/qxp LDB is controlled by Control and Status Registers(CSR) module.
16   The CSR module, as a system controller, contains the LDB's configuration
19   For i.MX8qxp LDB, each channel supports up to 24bpp parallel input color
22   them to use.  Two LDB channels from two LDB instances can work together in
23   LDB split mode to support a dual link LVDS display.  The channel indexes
27   For i.MX8qm LDB, each channel additionally supports up to 30bpp parallel
33   A side note is that i.MX8qm/qxp LDB is officially called pixel mapper in
36   consistency, this binding calls it LDB.
