+Subject: [PATCH] staging: vchiq_arm: Give vchiq children DT nodes
+
+vchiq kernel clients are now instantiated as platform drivers rather
+than using DT, but the children of the vchiq interface may still
+benefit from access to DT properties. Give them the option of a
+a sub-node of the vchiq parent for configuration and to allow
+them to be disabled.
