[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.

those cases separately at some places. Second, there might be several

|
W83781D chips available (well, actually, that is probably never done; but
|
|
|
|
it is a clean illustration of how to handle a case like that). Finally,
|
|
|
|
a specific chip may be attached to *both* ISA and SMBus, and we would
|
|
|
|
not like to detect it double. Fortunately, in the case of the W83781D at
|
|
|
|
least, a register tells us what SMBus address we are on, so that helps
|
|
|
|
a bit - except if there could be more than one SMBus. Groan. No solution

for this yet. */

[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 (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.
