hwmon: (lm73} Detect and report i2c bus errors

2013-01-17T16:46:22+00:00

commit 0602934f302e016e2ea5dc6951681bfac77455ef upstream.

If an LM73 device does not exist on an I2C bus, attempts to communicate
with the device result in an error code returned from the i2c read/write
functions.  The current lm73 driver casts that return value from a s32
type to a s16 type, then converts it to a temperature in celsius.
Because negative temperatures are valid, it is difficult to distinguish
between an error code printed to the response buffer and a negative
temperature recorded by the sensor.

The solution is to evaluate the return value from the i2c functions
before performing any temperature calculations.  If the i2c function did
not succeed, the error code should be passed back through the virtual
file system layer instead of being printed into the response buffer.

Before:

   $ cat /sys/class/hwmon/hwmon0/device/temp1_input
   -46

After:

   $ cat /sys/class/hwmon/hwmon0/device/temp1_input
   cat: read error: No such device or address

x86,AMD: Power driver support for AMD's family 16h processors

2012-12-17T19:06:52+00:00

commit 22e32f4f57778ebc6e17812fa3008361c05d64f9 upstream.

Add family 16h PCI ID to AMD's power driver to allow it report
power consumption on these processors.

hwmon: Fix chip feature table headers

2012-11-05T20:54:40+00:00

These got broken by recent patches fixing checkpatch warnings in these
drivers. The trick is that the patches themselves looked good, but the
source files after applying them do not. That's why I am not a big fan
of using tabs inside comments.

hwmon: (w83627ehf) Force initial bank selection

2012-11-05T20:54:39+00:00

Don't assume bank 0 is selected at device probe time. This may not be
the case. Force bank selection at first register access to guarantee
that we read the right registers upon driver loading.

hwmon: Only include of_match_table with CONFIG_OF_GPIO

2012-11-02T00:31:20+00:00

The following fixes build errors on sparc. Without any DT support,
of_match_ptr is NULL and the below is a no-op. However, if just
CONFIG_OF is defined then so is of_match_ptr.

All useful parts of the gpio-fan DT support rely on CONFIG_OF_GPIO
anyway, so of_match_table should too.

hwmon: (coretemp) Add support for Atom CE4110/4150/4170

2012-10-14T22:21:33+00:00

TjMax for the CE4100 series of Atom CPUs was previously reported to be
110 degrees C.

cpuinfo logs on the web show existing CPU types CE4110, CE4150, and CE4170,
reported as "model name : Intel(R) Atom(TM) CPU CE41{1|5|7}0 @ 1.{2|6}0GHz"
with model 28 (0x1c) and stepping 10 (0x0a). Add the three known variants
to the tjmax table.

hwmon: (pmbus) remove CONFIG_EXPERIMENTAL

2012-10-14T22:21:33+00:00

This config item has not carried much meaning for a while now and is
almost always enabled by default. As agreed during the Linux kernel
summit, remove it.

hwmon: Drop needless includes of

These drivers use no sleep or delay functions so they don't need to
include .
