From d2653e92732bd3911feff6bee5e23dbf959381db Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 29 Apr 2008 23:11:39 +0200 Subject: i2c: Add support for device alias names Based on earlier work by Jon Smirl and Jochen Friedrich. This patch allows new-style i2c chip drivers to have alias names using the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this point, the old i2c driver binding scheme (driver_name/type) is still supported.
