From d142d6be231713330f9c0d7ee52f23e1b3f19ee4 Mon Sep 17 00:00:00 2001 From: Richard Zhao Date: Wed, 12 Sep 2012 14:58:05 +0300 Subject: USB: chipidea: add imx usbmisc support i.MX usb controllers share non-core registers, which may include SoC specific controls. We turn it into a usbmisc device and usbmisc driver set operations needed by ci13xxx_imx driver. For example, Sabrelite board has bad over-current design, we can usbmisc to disable over-current detection.
