-Subject: [PATCH] bus: fsl-mc: add autorescan sysfs
-
-Add the autorescan sysfs in order to enable/disable the DPRC IRQs on
-which automatic rescan of the bus is performed. This is important when
-dynamic creation of objects is needed to happen in a timely manner because
-object creation can be bundled together.
