From 1fcaea7e4c932b2bcc2612fafec6e1917944d192 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 13 Jul 2011 11:29:18 +0200 Subject: at91: at91-ohci: configure overcurrent pins as input GPIOs 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.
