From 081554dca90cdc59d6ca64f83125e741078ea0d9 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Thu, 29 Sep 2016 11:40:30 +0200 Subject: phy: Introduce to_usbphy conversion function The generic phy support layer has the necessary list handling and phy retrieval functions, so we should reuse them for usb phys. This adds a phy_to_usbphy() conversion function which drivers can implement which attach to the generic phy layer and are really usb phys.
