Subject: [PATCH 3/3] USB: musb: dsps: propagate device-tree node
Date: Fri, 13 Apr 2018 17:15:05 +0200	[thread overview]
Message-ID: <20180413151505.32663-4-johan@kernel.org> (raw)
In-Reply-To: <20180413151505.32663-1-johan@kernel.org>

To be able to use DSPS-based controllers with device-tree descriptions
of the USB topology, we need to associate the glue device's device-tree
node with the child controller device.

Note that this can also be used to eventually let USB core manage
generic phys.

Also note that the other glue drivers will require similar changes to be
able to describe their buses in DT.
