If I am not wrong, CAMCC only enables the power domains that source the 
CAMCC block and it's register access. And for that, it only needs those 
power domains to be just enabled without any performance vote. Based on 
her comment, if MXA is always enabled (at min level), probably CAMCC 
driver doesn't need to enable or scale it explicitly. However, the 
camera devices that actually depend on this power domain for their core 
functionality need to scale this per the core clock corner. I can double 
check though.
