Date: Fri, 8 Jan 2016 13:44:22 +0800 [thread overview]
Message-ID: <1452231864-11171-1-git-send-email-peter.chen@freescale.com> (raw)
Hi all,
For some hard wired USB devices[1], we may need to use device tree to
describe them, the first patch is teach USB device to know device
node, the second patch is an example to show how to get properties
through device node at USB device (class) driver.
