From 6cb9310a3290beb8c0d31703a2e76b90a10b4ca0 Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Thu, 3 Oct 2013 18:12:31 +0300 Subject: usb: phy: omap: Add new device types and remove omap_control_usb3_phy_power() Add support for new device types and in the process rid of "ti,type" device tree property. The correct type of device will be determined from the compatible string instead. Introduce a compatible string for each device type. At the moment we support 4 types OTGHS, USB2, PIPE3 (e.g. USB3) and DRA7USB2. Update DT binding information to reflect these changes. Also get rid of omap_control_usb3_phy_power(). Just one function i.e. omap_control_usb_phy_power() will now take care of all PHY types.
