hwmon: (pmbus) Improve auto-detection of temperature status register

2011-07-10T15:54:29+00:00

It is possible that a PMBus device supports the READ_TEMPERATURE2 and/or
READ_TEMPERATURE3 registers but does not support READ_TEMPERATURE1.
Improve temperature status register detection to address this condition.

hwmon: (lm95241) Fix negative temperature results

2011-07-10T15:54:15+00:00

Negative temperatures were returned in degrees C instead of milli-Degrees C.
Also, negative temperatures were reported for remote temperature sensors even
if the chip was configured for positive-only results.

Fix by detecting temperature modes, and by treating negative temperatures
similar to positive temperatures, with appropriate sign extension.

hwmon: (lm95241) Fix chip detection code

2011-07-09T00:52:59+00:00

The LM95241 driver accepts every chip ID equal to or larger than 0xA4 as its
own, and other chips such as LM95245 use chip IDs in the accepted ID range.
This results in false chip detection.

Fix problem by accepting only the known LM95241 chip ID.

hwmon: (f71882fg) Add support for the F71869A

2011-07-03T11:32:53+00:00

The F71869A is almost the same as the F71869F/E, except that it has
the normal number of temp and pwm zones for a F71882FG derived chip,
rather then the limited number of the F71869F/E.

Handle errors on 8-bit register reads and writes too. Also use likely
and unlikely to make the functions faster on success.

hwmon: (pmbus) Auto-detect temp2 and temp3 registers/attributes

2011-07-01T22:56:07+00:00

Additional temperature attribute support is easy to detect, so do it.

hwmon: (pmbus) Improve fan detection

2011-07-01T22:56:06+00:00

Some PMBus devices return no error when reading fan speed registers, but don't
really support fans. Strengthen fan detection by also checking if fan
configuration registers exist.
