Subject: [PATCH 08/25] phy: sun4i: add support for USB phy0
Date: Thu, 27 Nov 2014 11:56:00 +0530 [thread overview]
Message-ID: <1417069577-1169-9-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1417069577-1169-1-git-send-email-kishon@ti.com>
From: Roman Byshko <rbyshko@gmail.com>
The driver for sun4i USB phys currently supports
only phy1 and phy2 which are used for USB host
controllers. This patch adds support for USB phy0,
which is used by the musb hdrc USB controller.
