Subject: [PATCH v2 2/3] usb: dwc3: pci: Register a software node for the dwc3 platform device
Date: Mon, 11 Jan 2021 17:10:44 +0300 [thread overview]
Message-ID: <20210111141045.14027-3-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20210111141045.14027-1-heikki.krogerus@linux.intel.com>
By registering the software node directly instead of just
the properties in it, the driver can take advantage of also
the other features the software nodes have.
Tested-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com>
