[PATCH] I2C: Move hwmon drivers (3/3)
Part 3: Move the drivers documentation, plus two general documentation files. Note that the patch "adds trailing whitespace", because it does move the files as-is, and some files happen to have trailing whitespace.

28Module Parameters
29-----------------
30
31* force_addr: int
32 Initialize the ISA address of the sensors
33* force_i2c: int
34 Initialize the I2C address of the sensors
35* init: int
36 (default is 1)
37 Use 'init=0' to bypass initializing the chip.
38 Try this if your computer crashes when you load the module.

40Description
41-----------
42
43This driver implements support for ISA accesses *only* for
44the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
45We will refer to them collectively as Winbond chips.
46
47This driver supports ISA accesses, which should be more reliable
48than i2c accesses. Also, for Tyan boards which contain both a
49Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
50using this driver will avoid i2c address conflicts and complex
51initialization that were required in the w83781d driver.
52
53If you really want i2c accesses for these Super I/O chips,
54use the w83781d driver. However this is not the preferred method
55now that this ISA driver has been developed.
56
57Technically, the w83627thf does not support a VID reading. However, it's
58possible or even likely that your mainboard maker has routed these signals
59to a specific set of general purpose IO pins (the Asus P4C800-E is one such
60board). The w83627thf driver now interprets these as VID. If the VID on
61your board doesn't work, first see doc/vid in the lm_sensors package. If
62that still doesn't help, email us at lm-sensors@lm-sensors.org.

64For further information on this driver see the w83781d driver
65documentation.
