Subject: [PATCH 3/3] at91-ohci: configure overcurrent pins as GPIOs
Date: Tue,  5 Jul 2011 11:05:28 +0200	[thread overview]
Message-ID: <1309856728-8265-3-git-send-email-thomas.petazzoni@free-electrons.com> (raw)
In-Reply-To: <1309856728-8265-1-git-send-email-thomas.petazzoni@free-electrons.com>

As a new overcurrent_pin[] array has been added to the at91_usbh_data
structure, those pins must be muxed to work properly. This commit
implements this muxing for all AT91 SoCs that support the AT91 OHCI.
