From mboxrd@z Thu Jan 1 00:00:00 1970 From: Johannes Pointner Subject: [PATCH] mfd: tps65217: add compatible string for subdevices Date: Mon, 22 Sep 2014 20:18:15 +0200 Message-ID: <5439652.jHp5aCCfrZ@lenovobook> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Samuel Ortiz , Lee Jones , AnilKumar Ch Cc: Rob Herring , Pawel Moll , Mark Rutland , Ian Campbell , Kumar Gala , devicetree@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org The TPS65217 is missing of_compatible string in the mfd_cell for its subdevices. This compatible string is necessary to use functions like of_find_backlight_by_node in backlight.c.
