From mboxrd@z Thu Jan 1 00:00:00 1970 From: anilkumar@ti.com (AnilKumar Ch) Date: Fri, 21 Sep 2012 21:19:11 +0530 Subject: [PATCH] ARM: dts: AM33XX: Add tsl2550 ambient light sensor DT data Message-ID: <1348242551-21293-1-git-send-email-anilkumar@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add tsl2550 ambient light sensor DT data to am335x-evm.dts. In AM335x EVM tsl2550 ambient light sensor is connected to I2C2 bus. So this patch adds child node inside i2c2 node with i2c slave address. TAOS tsl2550 sensor with two-wire SMBus serial interface. This patch also reduces I2C2 clock frequency to 100KHz from 400KHz because the maximum clock frequency of SMBus is 100KHz.
