From 3e3101d57c50f9e4fa1da947e4bd0bc5cbab4141 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Fri, 27 Sep 2013 11:53:30 +0530 Subject: usb: musb: omap2430: use the new generic PHY framework Use the generic PHY framework API to get the PHY. The usb_phy_set_resume and usb_phy_set_suspend is replaced with power_on and power_off to align with the new PHY framework. musb->xceiv can't be removed as of now because musb core uses xceiv.state and xceiv.otg. Once there is a separate state machine to handle otg, these can be moved out of xceiv and then we can start using the generic PHY framework.
