Subject: [PATCH v8 08/20] usb: phy: msm: Replace custom enum usb_mode_type with enum usb_dr_mode
Date: Mon, 28 Apr 2014 16:34:11 +0300	[thread overview]
Message-ID: <1398692063-11372-9-git-send-email-iivanov@mm-sol.com> (raw)
In-Reply-To: <1398692063-11372-1-git-send-email-iivanov@mm-sol.com>

From: "Ivan T. Ivanov" <iivanov@mm-sol.com>

Use enum usb_dr_mode and drop default usb_dr_mode from platform data.

USB DT bindings states: dr_mode: "...In case this attribute isn't
passed via DT, USB DRD controllers should default to OTG...",
so remove redundand field.
