From cb932e12d931f7973ac3ac66004977aec8fc87c0 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Tue, 25 Feb 2014 18:34:00 +0100 Subject: ARM: kirkwood: Add i2c alias so setting bus number When using platform_driver instantiation, the i2c bus was given bus number 0. The kirkwood-t5325 audio driver has this bus number hard coded for the address of the codec. However by default device tree i2c busses are dynamically allocated a bus number, starting from 1. Thus the kirkwood-t5325 cannot find its audio codec. By adding an alias in the DT file we can control the bus number and set it to 0. The codec can then be found.
