This is the second version of a new driver for the hardware monitoring features
of the Fintek F71882FG and F71883FG Super-I/O chips. This version has several
small fixes for flaws discovered during the review of the first version.
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
vid inputs are somewhat documented in the datasheet, but I know nothing about
vid/vrm stuff. Help with this would be much appreciated.

Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the
same as the Fintek F71805F/FG as far as hardware monitoring is concerned,
with two additional internal voltages monitored (VSB and battery), and 6
VID inputs (not yet supported.)
To make things a bit more confusing, two of the voltage input pins (in4
and in8) can be used for other functions. The driver reads the pin
configuration from the Super-I/O configuration space to decide whether
it must create interface files for these inputs or not.

it87: Add support for the IT8718F
The IT8718F is a Super-I/O chip with integrated hardware monitoring
functions. It is very similar to the IT8716F, so adding support to the

is that the IT8718F has up to 8 VID pins, instead of 6 for the older

For the IT8718F, the VID value can only be read from Super-I/O space.

This driver implements support for the National Semiconductor LM70
temperature sensor.
The LM70 temperature sensor chip supports a single temperature sensor.
It communicates with a host processor (or microcontroller) via an
SPI/Microwire Bus interface.
Communication with the LM70 is simple: when the temperature is to be sensed,
the driver accesses the LM70 using SPI communication: 16 SCLK cycles
comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's
complement digital temperature (sent via the SIO line), is available in the
driver for interpretation. This driver makes use of the kernel's in-core
SPI support.
