From f230d3f53d72d05bcb5666ab7e2eccd49c8b3a15 Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Mon, 19 Nov 2007 13:47:20 +0100 Subject: [ARM] 4650/1: AT91: New-style init of I2C, support for i2c-gpio The AT91 I2C driver is currently marked as "broken" due to hardware issues. This patch enables AT91-based platforms to also use the bitbanged GPIO for I2C. This updates platform setup logic (setting up an i2c-gpio device using the same pins as the i2c-at91 device, unless only the BROKEN driver is enabled). Also make use of the new-style initialization of I2C devices using i2c_register_board_info().
