CCI still physically lies within the camera subsystem and needs both the TOP_GDSC and the AHB/CPAS clocks to be on. devm_of_platform_populate() will ensure that subdevices will be probed. simple-mfd is essentially a hack/shortcut to call that function for nodes which aren't bound to drivers (e.g. because they represent something without a top-level software interface, which is rarely true and why it seems to be discouraged) Konrad
