Subject: [PATCH v3 5/6] usb: chipidea: let chipidea core device of_node equal's glue layer device of_node
Date: Wed, 20 Jul 2016 17:40:28 +0800 [thread overview]
Message-ID: <1469007629-31757-6-git-send-email-peter.chen@nxp.com> (raw)
In-Reply-To: <1469007629-31757-1-git-send-email-peter.chen@nxp.com>
From: Peter Chen <peter.chen@freescale.com>
At device tree, we have no device node for chipidea core,
the glue layer's node is the parent node for host and udc
device. But in related driver, the parent device is chipidea
core. So, in order to let the common driver get parent's node,
we let the core's device node equals glue layer device node.
