41 This driver implements support for ISA accesse
42 the Winbond W83627HF, W83627THF, W83697HF and
43 We will refer to them collectively as Winbond
44
45 This driver supports ISA accesses, which shoul
46 than i2c accesses. Also, for Tyan boards which
47 Super I/O chip and a second i2c-only Winbond c
48 using this driver will avoid i2c address confl
49 initialization that were required in the w8378
50
51 If you really want i2c accesses for these Supe
52 use the w83781d driver. However this is not th
53 now that this ISA driver has been developed.
54
55 The `w83627_HF_` uses pins 110-106 as VID0-VID
56 same pins as GPIO[0:4]. Technically, the `w836
57 VID reading. However the two chips have the id
58 it is possible or even likely for a w83627thf
59 to these pins despite their not being labeled
60 the w83627thf driver interprets these as VID.
61 doesn't work, first see doc/vid in the lm_sens
62 doesn't help, you may just ignore the bogus VI

68 Forcing the address
69 -------------------
70
71 The driver used to have a module parameter nam
72 be used to force the base I/O address of the h
73 This was meant as a workaround for mainboards
74 module parameter is gone for technical reasons
75 you can obtain the same result by using the is
76 lm-sensors) before loading the driver:
77
78 # Enter the Super I/O config space::
79
80 isaset -y -f 0x2e 0x87
81 isaset -y -f 0x2e 0x87
82
83 # Select the hwmon logical device::
84
85 isaset -y 0x2e 0x2f 0x07 0x0b
86
87 # Set the base I/O address (to 0x290 in this e
88
89 isaset -y 0x2e 0x2f 0x60 0x02
90 isaset -y 0x2e 0x2f 0x61 0x90
91
92 # Exit the Super-I/O config space::
93
94 isaset -y -f 0x2e 0xaa
95
96 The above sequence assumes a Super-I/O config
97 0x4e/0x4f is also possible.
