[PATCH] hwmon: New f71805f driver
This is my f71805f hardware monitoring driver ported from lm_sensors to Linux 2.6. This new driver differs from the other hardware monitoring drivers in that it is implemented as a platform driver. This might not be optimal yet (we would probably need a generic infrastructure and bus type for Super-I/O logical devices) but it is certainly much better than the i2c-isa solution. Note that this driver requires lm_sensors CVS. I hope to get it released as 2.10.0 soon. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
