Mh, 4 times sounds a bit too arbitrary to me. How about using a timeout in ms,
like 50ms, for retrying to read the EDID?

devm_ioremap_resource could not support such

Oh I see, both remap the same range. To be honest I do not like this. Is there
a need to map overlapping ranges in both drivers? How can you avoid race
conditions due to simultaneous accesses?

For imx8mq hdmi/dp, mdhp hdmi apb clock and core clock are managed

I noticed too this is the 1st access, so I have no idea what's wrong here.
Here is my /sys/kernel/debug/clk/clk_summary from using the regular DT without
enabling 'dcss', 'hdmi_phy' and 'mhdp_hdmi':
enable prepare protect
duty hardware
clock count count count rate
accuracy phase cycle enable
