Could we go with the naming scheme of "usb" + "p" + port number or do you have other suggestions? > Arnd > From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arun Ramamurthy Subject: Re: [PATCH 1/2] phy: usbphy: Add dt documentation for Broadcom Cygnus USB PHY driver Date: Tue, 17 Feb 2015 12:00:49 -0800 Message-ID: <54E39DF1.50409@broadcom.com> References: <1424200821-16368-1-git-send-email-arun.ramamurthy@broadcom.com> <1424200821-16368-2-git-send-email-arun.ramamurthy@broadcom.com> <8242260.cl4QTECoeX@wuerfel> Mime-Version: 1.0 Content-Type: text/plain; charset="windows-1252"; format=flowed Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <8242260.cl4QTECoeX@wuerfel> Sender: linux-kernel-owner@vger.kernel.org To: Arnd Bergmann Cc: Kishon Vijay Abraham I , Rob Herring , Pawel Moll , Mark Rutland , Ian Campbell , Kumar Gala , devicetree@vger.kernel.org, Jonathan Richardson , Scott Branden , Ray Jui , linux-arm-kernel@lists.infradead.org, bcm-kernel-feedback-list@broadcom.com, linux-kernel@vger.kernel.org, Dmitry Torokhov , Anatol Pomazau List-Id: devicetree@vger.kernel.org Thank you for the review Arnd.
