power-domains = <&rpmhpd SM8250_MMCX>; == MMCX_LEVEL required for camcc
power-domains = <&camcc TITAN_TOP_GDSC>; required for cci/camss

now that you ask the question about MX_LEVEL you're making me doubt we 
have a 100% complete representation upstream TB perfectly honest, 
warrants a deep dive..

I just remember that on 8250 we tripped over MMCX not being switched on 
when - display I think was switched off.
