From e842b84c8e7221c45c8dbd7de09185c6149e1cf9 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 23 Mar 2015 09:52:48 +1100 Subject: usb: phy: Add interface to get phy give of device_node. Split the "get phy from device_node" functionality out of "get phy by phandle" so it can be used directly. This is useful when a battery-charger is intimately associated with a particular phy but handled by a separate driver. The charger can find the device_node based on sibling relationships without the need for a redundant declaration in the devicetree description. As a peripheral that gets a phy will often want to register a notifier block, and de-register it later, that functionality is included so the de-registration is automatic.
