Subject: [PATCH v2 07/11] ARM: davinci: da8xx: Add USB PHY platform declaration
Date: Wed, 16 Mar 2016 21:26:40 -0500	[thread overview]
Message-ID: <1458181615-27782-8-git-send-email-david@lechnology.com> (raw)
In-Reply-To: <1458181615-27782-1-git-send-email-david@lechnology.com>

There is now a proper phy driver for the DA8XX SoC USB PHY. This adds the
platform device declarations needed to use it.
