From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ben Hutchings Subject: [PATCH v2] ARM: dts: dra7xx: Fix compatible string for PCF8575 chip Date: Wed, 16 Mar 2016 16:52:30 +0000 Message-ID: <1458147150.20441.2.camel@codethink.co.uk> Mime-Version: 1.0 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit Return-path: Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-omap-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Cc: CT kernel , Grygorii Strashko , devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-omap@vger.kernel.org The binding definition for the PCF857x GPIO expanders doesn't mention a "ti,pcf8575" compatible string. This is apparently because TI is only a second source - there is no functional difference between PCF8575 chips manufactured by TI and NXP, and the same board might be populated with either depending on availability. This is not a problem in practice because the I2C core uses of_modalias_node() before matching drivers and this strips the manufacturer name.
