From dda9cd289ca781593354cf9ad9c091aa5a1260a8 Mon Sep 17 00:00:00 2001 From: Marc Dietrich Date: Thu, 19 May 2011 14:08:26 +0200 Subject: [PATCH] ARM: tegra: paz00: register i2c busses This adds support for the i2c busses on paz00. The 3rd bus is reserved for the nvec, which acts as master and i2c-tegra has not yet support for this kind of operation. The sound codec (alc5632) is connected to the first bus and will be added once the codec and glue driver is upstream. The thermal sensor (atd7461) is connected to dvc as usual, but will not be added now because i2c-tegra still misses probe support (needs I2C_FUNC_SMBUS_EMUL).
