hwmon: (max6642): Better chip detection schema

2011-06-04T17:34:28+00:00

Improve detection of MAX6642 by reading non existing registers (0x04, 0x06
and 0xff). Reading those registers returns the previously read value.

hwmon: (coretemp) Further relax temperature range checks

2011-06-02T03:10:40+00:00

Further relax temperature range checks after reading the IA32_TEMPERATURE_TARGET
register. If the register returns a value other than 0 in bits 16..32, assume
that the returned value is correct.

This change applies to both packet and core temperature limits.

hwmon: (coretemp) Fix TjMax detection for older CPUs

2011-06-02T03:10:31+00:00

Commit a321cedb12904114e2ba5041a3673ca24deb09c9 excludes CPU models 0xe, 0xf,
0x16, and 0x1a from TjMax temperature adjustment, even though several of those
CPUs are known to have TiMax other than 100 degrees C, and even though the code
in adjust_tjmax() explicitly handles those CPUs and points to a Web document
listing several of the affected CPU IDs.

Reinstate original TjMax adjustment if TjMax can not be determined using the
IA32_TEMPERATURE_TARGET register.

hwmon: (coretemp) Relax target temperature range check

2011-06-01T18:11:28+00:00

The current temperature range check of MSR_IA32_TEMPERATURE_TARGET
seems too strict to me, some TjMax values documented in
Documentation/hwmon/coretemp wouldn't pass. Relax the check so that
all the documented values pass.

hwmon: (max6642) Rename temp_fault sysfs attribute to temp2_fault

2011-06-01T18:11:27+00:00

The temp_fault sysfs attribute is wrong, it should be temp2_fault instead.

hwmon: (coretemp) Fix section mismatch

2011-05-27T09:24:54+00:00

chk_ucode_version() is only called from coretemp_probe() which is
__devinit, so it can be marked __devinit too.

hwmon: New driver for the SMSC EMC6W201

2011-05-25T18:43:33+00:00

This is a new driver for the SMSC EMC6W201 hardware monitoring device.
The device is functionally close to the EMC6D100 series, but is
register-incompatible.
