The two channels + cannot be used simultaneously, that is to say, the user should pick one of + them to use. Two LDB channels from two LDB instances can work together in + LDB split mode to support a dual link LVDS display. The channel indexes + have to be different. Channel0 outputs odd pixels and channel1 outputs + even pixels. + + For i.MX8qm LDB, each channel additionally supports up to 30bpp parallel + input color format. The two channels can be used simultaneously, either + in dual mode or split mode. In dual mode, the two channels output identical + data. In split mode, channel0 outputs odd pixels and channel1 outputs even + pixels. + + A side note is that i.MX8qm/qxp LDB is officially called pixel mapper in + the SoC reference manuals. The pixel mapper uses logic of LDBs embedded in + i.MX6qdl/sx SoCs, i.e., it is essentially based on them.
