|
* monitoring.
|
|
|
|
*
|
|
|
|
* The IT8705F is an LPC-based Super I/O part that contains UARTs, a
|
|
|
|
* parallel port, an IR port, a MIDI port, a floppy controller, etc., in
|
|
|
|
* addition to an Environment Controller (Enhanced Hardware Monitor and
|
|
|
|
* Fan Controller)
|
|
|
|
*
|
|
|
|
* This driver supports only the Environment Controller in the IT8705F and
|
|
|
|
* similar parts. The other devices are supported by different drivers.

[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (3/9)
Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360,
sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to
explicitely register with i2c-isa. For hybrid drivers (it87, lm78,
w83781d), we now have two separate instances of i2c_driver, one for the
I2C interface of the chip, and one for ISA interface. In the long run,
the one for ISA will be replaced with a different driver type.
At this point, all drivers are working again, except for missing
dependencies in Kconfig.

[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (5/9)
Call the ISA chip drivers detection function directly instead of relying
on i2c_detect. The net effect is that address lists won't be handled
anymore, but they were mostly useless in the ISA case anyway (pc87360,
smsc47m1, smsc47b397 had already dropped them).
We don't need to handle multiple devices, all we may need is a way to
force a given address instead of the original one (some drivers already
do: sis5595, via686a, w83627hf), and, for drivers supporting multiple
chips, a way to force one given kind. All this may be added later on
demand, but I actually don't think there will be much demand.

[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (3/9)
Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360,
sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to
explicitely register with i2c-isa. For hybrid drivers (it87, lm78,
w83781d), we now have two separate instances of i2c_driver, one for the
I2C interface of the chip, and one for ISA interface. In the long run,
the one for ISA will be replaced with a different driver type.
At this point, all drivers are working again, except for missing
dependencies in Kconfig.
