From mboxrd@z Thu Jan 1 00:00:00 1970 From: Phil Reid Subject: [PATCH 1/5] i2c: mux: pca954x: Add missing pca9542 definition to chip_desc Date: Wed, 4 Jan 2017 17:29:53 +0800 Message-ID: <1483522197-38819-2-git-send-email-preid@electromag.com.au> References: <1483522197-38819-1-git-send-email-preid@electromag.com.au> Return-path: In-Reply-To: <1483522197-38819-1-git-send-email-preid@electromag.com.au> Sender: linux-i2c-owner@vger.kernel.org To: peda@axentia.se, wsa@the-dreams.de, robh+dt@kernel.org, mark.rutland@arm.com, preid@electromag.com.au, linux-i2c@vger.kernel.org, devicetree@vger.kernel.org List-Id: devicetree@vger.kernel.org The spec for the pca954x was missing. This chip is the same as the pca9540 except that it has interrupt lines. While the i2c_device_id table mapped the pca9542 to the pca9540 definition the compatible table did not. In preparation for irq support add the pca9542 definition.
