How would it break ?
We park the clock to XO it never gets turned off this way.
Parking the parent at XO doesn't ensure the branch clock is always
on, it can be disabled by consumers or CCF if modelled.
If the CCF disables this clock in late init, then the clock stays in
disabled state until it is enabled again explicitly. Hence it is
recommended to not model such always-on clocks.
What is the use-case to keep that clock always-on unless/util someone
wants camss ?
The clock also has dependency on MMCX rail, this rail anyway will be OFF
until there is a use-case. So the clock will also be OFF.
I've tested this patch on sc8280xp and it works just fine.
Is the cam_cc_gdsc_clk clock ON after the boot up?
