From 29fb52ca78b4e265ec6c626b0c7b2927953949cf Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 11 Mar 2010 10:01:17 -0500 Subject: [PATCH] drm/radeon/kms: expose thermal/fan i2c buses Look up i2c bus in the power table and expose it. You'll need to load a hwmon driver for any chips on the bus, this patch just exposes the bus.
