From bb1e7cde624d44edf75c1b607fd6c60e038f98dd Mon Sep 17 00:00:00 2001 From: Tom Warren Date: Fri, 21 Dec 2012 16:09:52 -0700 Subject: [PATCH] Tegra30: I2C: Enable I2C driver on Cardhu Tested all 5 'buses', i2c probe enumerates device addresses on all but dev 4 (I2C4) [no devices on that bus on my Cardhu]. Note that this uses the extant tegra_i2c.c driver w/o modification.
