From 657b306a7bdfca4ae1514b533a0e7c3c6d26dbc6 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Thu, 6 Sep 2012 20:27:06 +0530 Subject: usb: phy: add a new driver for omap usb2 phy All phy related programming like enabling/disabling the clocks, powering on/off the phy is taken care of by this driver. It is also used for OTG related functionality like srp. This also includes device tree support for usb2 phy driver and the documentation with device tree binding information is updated. Currently writing to control module register is taken care in this driver which will be removed once the control module driver is in place.
