Subject: [PATCH v1 2/6] ARM: dts: imx7d-cl-som: add nodes for usbh, and usbotg2
Date: Tue,  5 Dec 2017 14:27:03 -0800	[thread overview]
Message-ID: <20171205222707.11302-3-tyler@opensourcefoundries.com> (raw)
In-Reply-To: <20171205222707.11302-1-tyler@opensourcefoundries.com>

From: Tyler Baker <tyler@opensourcefoundries.com>

Add device tree nodes for the USB hub, and USB OTG. i2c2 on this
platform supports low state retention power state so lets use it.
