From 723487a6ff50bb88c628a859aeac3fe721f0d1fa Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Wed, 13 May 2015 15:26:52 +0300 Subject: [PATCH] phy: helpers for USB ULPI PHY registering ULPI PHYs need to be bound to their controllers with a lookup. This adds helpers that the ULPI drivers can use to do both, the registration of the PHY and the lookup, at the same time.
