2012-07-22hwmon: (applesmc) Ignore some temperature registersHenrik Rydberg1-28/+47
Not all sensors in the T range are useful temperatures. This patch creates a subset of sensors to be exported to userland, excluding the unknown types. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2012-07-22hwmon: (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.

2012-07-22hwmon: (w83781d) Fix compile warningGuenter Roeck1-3/+3
The following compile warning may be seen if the driver is compiled with -Wuninitialized: drivers/hwmon/w83781d.c: warning: 'sc_addr[1]' may be used uninitialized in this function [-Wuninitialized] While this is a false positive, it is annoying in nightly builds, and may help to conceal real problems. The current code is quite tricky, and and it is easy to rearrage the code to make the warning disappear. So fix it.

2012-07-22hwmon: (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).

2012-07-22hwmon: Honeywell Humidicon HIH-6130/HIH-6131 humidity and temperature sensor ↵Iain Paton3-0/+304
driver This is a new driver for the Honeywell Humidicon HIH-6130/HIH-6131 humidity sensor. The driver is based on the existing Sensiron sht21 driver with the necessary changes to the probe, update_measurements and conversion functions necessary to use the Honeywell sensors. There's no difference between the 6130 & 6131 other than the 6131 having an external condensation filter attached.
