From ee896e348cf6f323a00e4ee52e6386f515f86cee Mon Sep 17 00:00:00 2001 From: Hema HK Date: Thu, 17 Feb 2011 12:06:07 +0530 Subject: usb: otg: OMAP4430: Introducing suspend function for power management Introduced the suspend/resume function for the OMAP4430 internal PHY. This will be used by the twl6030-usb transceiver driver. Moved the clock enable/disable function calls and power on/off of the PHY code from power on/off functions to suspend/resume function. Pass the suspend function through board data for OMAP4430sdp and OMAP4panda. This will be used by the twl6030-usb transceiver driver.
