From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lee Jones Subject: [PATCH 4/7] i2c: Match using traditional OF methods, then by vendor-less compatible strings Date: Wed, 4 Jun 2014 13:09:53 +0100 Message-ID: <1401883796-17841-5-git-send-email-lee.jones@linaro.org> References: <1401883796-17841-1-git-send-email-lee.jones@linaro.org> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1401883796-17841-1-git-send-email-lee.jones@linaro.org> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org Cc: devicetree@vger.kernel.org, wsa@the-dreams.de, linus.walleij@linaro.org, linux-i2c@vger.kernel.org, grant.likely@linaro.org, Lee Jones List-Id: linux-i2c@vger.kernel.org This function provides a single call for all I2C devices which need to match firstly using traditional OF means i.e by of_node, then if that fails we attempt to match using the supplied I2C client name with a list of supplied compatible strings with the ',' string removed. The latter is required due to the unruly naming conventions used currently by I2C devices.
