From fa35757ae0a5a88bd1b7df8578ee9dac9d147c64 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5/9] interconnect: qcom: qcm2290: Hook up MAS_APPS_PROC's bus
clock
This single node has its own clock which seems to be responsible for
transactions between CPUSS (CPU + some stuff) and the GNOC. See [1]
for reference.
Define it and hook it up.
