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.
