From 5d3c28b5a42df5ceaa854901ba2cccb76883c77e Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Fri, 25 Jan 2013 08:03:25 +0530 Subject: usb: otg: add device tree support to otg library Added an API devm_usb_get_phy_by_phandle(), to get usb phy by passing a device node phandle value. This function will return a pointer to the phy on success, -EPROBE_DEFER if there is a device_node for the phandle, but the phy has not been added, or a ERR_PTR() otherwise.
