The bank switching code assumes that the bank selector is set to 0
when the driver is loaded. This might not be the case. This is exactly
the same bug as was fixed in the w83627ehf driver two months ago:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0956895aa6f8dc6a33210967252fd7787652537d
In practice, this bug was causing the sensor thermal types to be
improperly reported for my W83627THF the first time I was loading the
w83627hf driver. From the driver history, I'd say that it has been
broken since September 2005 (when we stopped resetting the chip by
default at driver load.)

We need to read the fan clock dividers at initialization time,
otherwise the code in store_fan_min() may use uninitialized values.
That's pretty much the same bug and same fix as for the w83627ehf

This patch adds support for the SMSC SCH3112, SCH3114, and SCH3116 Super-I/O
chips. These chips feature identical hardware monitoring capabilites with the
expection that some of the fan inputs and pmw outputs don't exist.
The hardware monitoring features of the SCH311x chips can only be accessed via
the ISA bus. The driver therefore registers as a platform driver, if such a
chip is detected.

This lets us get rid of macro-generated functions and shrinks the
driver size by about 10%. I used a new style suggested by Mark M.
Hoffman to retrieve the channel number. Instead of:
struct sensor_device_attribute *sda = to_sensor_dev_attr(attr);
int nr = sda->index;
I do:
int nr = to_sensor_dev_attr(attr)->index;
This looks better, and even allows the compiler to do some minor
optimizations.

This version of the driver does not support the pwm part of these chips (yet).
I'll first design a sysfs api for this and post that for discussion, and then
implement pwm support as an incremental patch over this one.
This driver supports all sensors of this chip, except for the vid inputs. The

Don't assume that the default bank is 0. For one thing, we don't even
set it to 0 when the driver is loaded, so the initial state might be

the bank value is 0 is not safe.
