From 01729ccf19b3c136cd93f8837b0a2761c23da700 Mon Sep 17 00:00:00 2001 From: "Vishwanathrao Badarkhe, Manish" Date: Wed, 6 Feb 2013 15:06:22 +0530 Subject: ARM: davinci: da850: add DT node for I2C0 Add I2C0 device tree and pin muxing information to da850-evm. Also, add OF_DEV_AUXDATA for I2C0 controller driver in da850 board dt file to use I2C0 clock. Verified i2c0 node gets created in sys class interface as "/sys/class/i2c-dev/i2c-0/subsystem/i2c-0". nsekhar@ti.com: tested using i2cdetect and i2cdump.
