Note that this patch depends on the patch 'phy: Add LVDS configuration options',
which has already been sent with the following series to add Mixel combo PHY
found in i.MX8qxp:
https://www.spinics.net/lists/arm-kernel/msg879957
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. This patch supports the
