The name of the power domains is CAMSS_TOP_GDSC (seems you misread)
For the power domain to successfully turn on, the MNoC needs to be
turned on (empirical evidence). The way to do it is to request a
nonzero vote on this interconnect path
(presumably because the GDSC or its invisible providers require
something connected over that bus to carry out their enable sequences).
Taniya should be able to explain in more detail
