I see DCSS and HDMI controller/PHY sit in displaymix in a system
bus diagram(internal only), but LCDIF and MIPI DSI controller/PHY
are not in that mix.  So, it seems that the "gpc_disp" power domain
defined in imx8mq.dtsi supplies power for DCSS and HDMI
controller/PHY only, though nxp,imx8mq-dcss.yaml doesn't even
allow a "power-domains" property...

Assuming that system bus diagram is correct and "gpc_disp" power domain
does supply power for everything in displaymix only:

We currently enable the mipi power domain for the mipi dphy and nwl
bridge only but not for LCDIF itself assuming it's not needed (as there's
other outputs LCDIF can drive). I *think* this is correct but maybe
Marek or Liu can confirm?

I don't see anything which would resemble power domains like on 
MX8MM/N/P on the MQ MXSFB, there are such domains for the VPU and DCSS, 
but not MXSFB. So
