Subject: [PATCH] usb: chipidea-imx: Fix usb initialization
Date: Tue,  5 Mar 2013 21:11:08 +0400	[thread overview]
Message-ID: <1362503468-11451-1-git-send-email-shc_work@mail.ru> (raw)

This patch fix chipidea-imx usb initialization.
"imx_chipidea_port_init" was moved before PORTSC setup in the
commit "USB i.MX chipidea: implement post init support". This
change breaks usb function with ULPI. Patch moves port initialization
back after PORTSC setup, so it works again.
