From mboxrd@z Thu Jan 1 00:00:00 1970 From: NeilBrown Subject: [PATCH 0/2] Allow twl4030_charger to find phy reliably. Date: Mon, 23 Mar 2015 09:52:48 +1100 Message-ID: <20150322225053.22311.45510.stgit@notabene.brown> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Sender: linux-pm-owner@vger.kernel.org To: Mark Rutland , Pawel Moll , Ian Campbell , Sebastian Reichel , Felipe Balbi , Rob Herring , Kumar Gala Cc: devicetree@vger.kernel.org, linux-usb@vger.kernel.org, linux-kernel@vger.kernel.org, Pavel Machek , linux-pm@vger.kernel.org List-Id: devicetree@vger.kernel.org The twl4030_charger is physically paired with the twl4030 USB phy, so the drivers need to be able to reliably find each other. twl4030_charger currently uses usb_get_phy(), which works if there is only one phy to choose from, but is not reliable in more complex configurations. These patches add a new interface to allow a phy to be found given a device node, and then use that interface in twl4030_charger so that it finds its sibling in the devicetree, and gets the phy associated with that. === This is a resend with improved documentation. I'm hoping this can go in to the next merge window, though should it go through usb/phy or power???
