* Documentation: update broken web addresses.Justin P. Mattock2010-08-04
| | | | | | | | | | | | | | | | | | Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

* hwmon: (ltc4245) Read only one GPIO pinIra W. Snyder2010-05-27
| | | | | | | | | | | | | Read only one of the GPIO pins as an analog voltage. The ADC can be switched to a different GPIO pin at runtime, but this is not supported. Previously, this driver would report the analog voltage of the currently selected GPIO pin as all three GPIO voltages: in9_input, in10_input and in11_input. Signed-off-by: Ira W.

* hwmon: Driver for TI TMP102 temperature sensorSteven King2010-05-27
| | | | | | | | | | | | | | | Driver for the TI TMP102. The TI TMP102 is similar to the LM75. It differs from the LM75 by having a 16-bit conf register and the temp registers have a minimum resolution of 12 bits; the extended conf register can select 13-bit resolution (which this driver does) and also change the update rate (which this driver currently doesn't use).

This implementation fits very well in our standard sysfs interface. I implemented the old and not the new interface because the only chip I have at hand is an old one, and the new interface is more difficult to map to the standard sysfs interface. Adding support later should be possible though, if someone with a supported chip is interested. Signed-off-by: Jean Delvare <khali@linux-fr.org>

At this point this is more of a proof-of-concept, we don't do anything terribly useful on SMBus alert: we simply log the event. But this could later evolve into libsensors signaling so that user-space applications can take an appropriate action.

Note that this bit of the patch: - val = SENSORS_LIMIT(val, 0, 255); + + if (data->type == f71889fg) + val = SENSORS_LIMIT(val, -128, 127); + else + val = SENSORS_LIMIT(val, 0, 127); Changes behaviour for already supported models, the new behaviour is correct as the already supported models have bit 7 of the involved registers fixed at 0, so the previous behaviour which allowed setting temp zone limits > 127 was not correct.

It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve the example code to be at least useable, as in not causing harm (as shown below). Code can still be improved further, but this adds some basic safeguards. 1. hpfall *MUST* mlockall(MCL_CURRENT|MCL_FUTURE); itself! Since the Program sits and waits most of the time it becomes very likely swapped out. If it gets woken up when the laptop drops from the table while it is swapped out it actually triggers harddrive activity! 2. Daemonize hpfall using 'daemon(0,0)' (quick and dirty). 3. Give hpfall realtime priority. Should give a chance that it has less latency when woken up.
