2012-08-22hwmon: (asus_atk0110) Add quirk for Asus M5A78LLuca Tettamanti1-0/+6
The old interface is bugged and reads the wrong sensor when retrieving the reading for the chassis fan (it reads the CPU sensor); the new interface works fine.

2012-07-27hwmon: (applesmc) Decode and act on read/write status codesHenrik Rydberg1-24/+46
The behavior of the SMC has changed several times over the years, causing read failures in the driver. It seems the problem can be explained by a shift in SMC speed combined with improper action on status codes. We should first wait for the SMC to settle, which was the most frequent response on the old slow machines. Then, if the SMC is busy, we need to try again later by resending the command. This was the most likely response until 2012. Now, with a shorter wait time, we are again most likely to poll while the SMC is settling, and as a result we see high failure rates on many old and new models. With the distinction between busy and failure, we can also wait longer before retrying, without sacrificing speed. This seems to bring failures down to virtually zero on all models.

2012-07-27hwmon: (jc42) Don't reset hysteresis on device removalJean Delvare1-3/+10
Restoring the configuration register on device removal has the side effect of also resetting the hysteresis value. This is inconsistent as the other limits are not reset, only hysteresis. So, following the principle of least surprise, preserve the hysteresis value when restoring the configuration register.

2012-07-21hwmon: (applesmc) Allow negative temperature valuesHenrik Rydberg1-11/+8
There are many userland reports of sensors with unreasonably small and large temperatures. There seem to be several reasons for this: Firstly, the major sensor type (sp78) is actually a signed number. This explains why some sensors show very small or large values - they are in fact all small, but of different sign. Secondly, the other sensor type (1-hex) is not properly understood; it may be that it is not a temperature after all. Thirdly, some sensors are differential in nature, showing changes over time rather than absolute numbers. This explains why those values are small and of varying sign. This patch interprets the sp78 type as signed short, but keeps the original scaling. For other types, -EINVAL is returned, since the nature of those sensors is unknown.

The current code is quite tricky, and and it is easy to rearrage the code to make the warning disappear. So fix it.

2012-07-21hwmon: (applesmc) Shorten minimum wait timeHenrik Rydberg1-1/+1
The 2012 series of MacBooks have a faster SMC, and the current driver timings do not work at all. Tests show that decreasing the minimum wait time, from 64 us to 16 us, works well. Since this is still larger than the original minimum of 10 us used before 2008, there is nothing inherently problematic with changing it. The fail frequency on older machines seems to increase slightly, but not enough to be noticeable. Tested on MBA11, MBA31, MBA5,2, MBP9,2. The patch was originally written by adamski99 (ubuntuforums.org) and later tested by janhouse (bbs.archlinux.org).
