2009-12-14i2c: Drop I2C_CLIENT_INSMOD_2 to 8Jean Delvare
These macros simply declare an enum, so drivers might as well declare it themselves. This puts an end to the arbitrary limit of 8 chip types per i2c driver. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2009-12-14i2c: Get rid of struct i2c_client_address_dataJean Delvare
Struct i2c_client_address_data only contains one field at this point, which makes its usefulness questionable. Get rid of it and pass simple address lists around instead. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>
2009-12-14i2c: Drop the kind parameter from detect callbacksJean Delvare
The "kind" parameter always has value -1, and nobody is using it any longer, so we can remove it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Wolfram Sang <w.sang@pengutronix.de>

2009-10-24hwmon: (dme1737) No vid attributes for SCH311xJean Delvare
The SCH311x chips do not have VID inputs, so the cpu0_vid and vrm attributes shouldn't be created for them.

2009-09-23dme1737: Keep index within pwm_config[]Roel Kluin
The static code scanner "Parfait" reported this because pwm_config is only 3 bytes - pwm_config[3] is out of range. Since this code path is never called with ix == 3 (the device has no PWM4 output) this doesn't change anything in practice. But to encourage testing with Parfait, lets make the warning go away...

2009-01-07hwmon: Check for ACPI resource conflictsJean Delvare
Check for ACPI resource conflicts in hwmon drivers. I've included all Super-I/O and PCI drivers. I've voluntarily left out: * Vendor-specific drivers: if they conflicted on any system, this would pretty much mean that they conflict on all systems, and we would know by now. * Legacy ISA drivers (lm78 and w83781d): they only support chips found on old designs were ACPI either wasn't supported or didn't deal with thermal management. * Drivers accessing the I/O resources indirectly (e.g. through SMBus): the checks are already done where they belong, i.e. in the bus drivers.

2008-10-14hwmon: (dme1737) Convert to a new-style i2c driverJean Delvare
The new-style dme1737 driver implements the optional detect() callback to cover the use cases of the legacy driver. I don't actually expect any new-style device for that driver, but as the old i2c API is going away soon, we have to switch to the new one.

2008-10-14hwmon: (dme1737) Be less i2c-centricJean Delvare
The dme1737 driver support both LPC (ISA) and SMBus devices. At the moment it's rather i2c-centric, and LPC variants use a fake i2c_client for some operations. In a near future, i2c_client will be allocated by i2c-core rather than by the device drivers, so non-i2c drivers will not have one. As a preparation step, change the driver code to no longer assume that an i2c_client structure is always available. No functional change.

2008-08-06hwmon: (dme1737) Add support for the SMSC SCH5027Juerg Haefliger
Add support for the SCH5027. The differences to the DME1737 are: - No support for programmable temp offsets - In auto mode, PWM outputs stay on min value if temp goes below low threshold and can't be programmed to fully turn off - Different voltage scaling - No VID input Signed-off-by: Juerg Haefliger <juergh@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-07-31hwmon: (dme1737) demacrofy for readabilityJuerg Haefliger
This patch gets rid of a couple of macros previously used for sysfs attribute generation and manipulation. This makes the source a little bigger but a lot more readable and maintainable.

2008-02-07hwmon: Let the user override the detected Super-I/O device IDJean Delvare
While it is possible to force SMBus-based hardware monitoring chip drivers to drive a not officially supported device, we do not have this possibility for Super-I/O-based drivers. That's unfortunate because sometimes newer chips are fully compatible and just forcing the driver to load would work. Instead of that we have to tell the users to recompile the kernel driver, which isn't an easy task for everyone. So, I propose that we add a module parameter to all Super-I/O based hardware monitoring drivers, letting advanced users force the driver to load on their machine. The user has to provide the device ID of a supposedly compatible device. This requires looking at the source code or a datasheet, so I am confident that users can't randomly force a driver without knowing what they are doing. Thus this should be relatively safe. As you can see from the code, the implementation is pretty simple and unintrusive.

2007-10-10hwmon: (dme1737) Add sch311x supportJuerg Haefliger
This patch adds support for the SMSC SCH3112, SCH3114, and SCH3116 Super-I/O chips. These chips feature identical hardware monitoring capabilites with the expection that some of the fan inputs and pmw outputs don't exist. The hardware monitoring features of the SCH311x chips can only be accessed via the ISA bus. The driver therefore registers as a platform driver, if such a chip is detected.

Add support for the hardware monitoring and fan control capabilities of the SMSC DME1737 and Asus A8000 Super-I/O chips.
