Subject: [PATCH 0/5] Support enabling interconnect path for GDSC for fixing
 Milos camcc

Some power domains like CAMSS_TOP_GDSC requires the enablement of the
multimedia NoC on newer SoCs like Milos.

Add support for getting an interconnect path as specified in the SoC
clock driver, and enabling/disabling that interconnect path when the
GDSC is being enabled/disabled.

Then specify that dependency in the camcc-milos driver and add it to the
dt-bindings and milos.dtsi.
