The problem is trivial to reproduce and the fix is trivial to verify,
it's sufficient to enable SM8550 camera clock controller and a CCI
controller, for instance on SM8550-QRD CCI0 or CCI1 can be enabled:
&cci0 {
status = "okay";
};
I made a special effort to check that the power domain in SM8550 camcc
is sufficient to be replaced, and Titan and other provided GDSCs can
be turned on/off, if the clock controller is disconneced from MMCX and
MMCX is off according to /sys/kernel/debug/pm_genpd/pm_genpd_summary.
