Subject: [RFCv1 3/3] ARM: dts: meson8b: odroidc1: enable the OTG capable USB controller
Date: Wed, 23 Jan 2019 15:12:09 +0000	[thread overview]
Message-ID: <20190123151209.2080-4-linux.amoon@gmail.com> (raw)
In-Reply-To: <20190123151209.2080-1-linux.amoon@gmail.com>

Override the dr_mode from "host" to "otg" for USB_HOST controller (usb0)
changes help usb_phy0->usb0 initialization of OTG bus port.

Changes fix the below warning.
