I've tested this series on i.MX8qm MEK and i.MX8qxp MEK with LVDS
panel and LVDS to HDMI.

To test LVDS displays, compatible strings "fsl,imx8qm-lvds-csr" and
"fsl,imx8qxp-mipi-lvds-csr" need to be added in simple-pm-bus.c by
patch [1] and a clock patch [2] is needed if you use relatively new
SCU firmware in bootloader.

Aside from that, I just wrote/changed device tree.
See attached DT files for LVDS panel test.
