From 9955a7835bf376e12482583958b2661f501b868b Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Mon, 21 Dec 2015 14:24:13 +0530 Subject: phy: omap-usb2: use *syscon* framework API to power on/off the PHY Deprecate using phy-omap-control driver to power on/off the PHY, and use *syscon* framework to do the same. This handles powering on/off the PHY for the USB2 PHYs used in various TI SoCs.
