| * hwmon: (emc1403) Make all hyst attributes except for temp1_crit_hyst read-onlyGuenter Roeck2014-05-221-2/+5
| | | | | | | | | | | | | | | | | | | | All chips in this chip series only support a single hysteresis value. Having multiple writable hysteresis attributes is therefore confusing, since a single write affects all hysteresis temperatures. Make all but one (temp1_crit_hyst) read-only.

| * hwmon: (lm77) Do not preserve hysteresis when updating critical temp limitGuenter Roeck2014-05-221-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | Updating the hysteresis value when updating the critical temperature limit was following the rule of 'least surprise'. However, it had the undesirable side effect of changing the hysteresis for all other attributes, which defeats the purpose of least surprise. In addition, it could result in invalid hysteresis values if the resulting hysteresis was too large. In such cases the resulting hysteresis ended up changed anyway, which again defeats the purpose. So drop that code and document the new behavior. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | The hysteresis register is shared among both temperature sensors. This means changing one also affects the other. To avoid confusion, established way to express this is to make only the first instance writable and keep all other instances as read-only. Otherwise users may be confused that changing the second writable value also affects the first, while it is more obvious that a writable value may affect a different read-only value.

* hwmon: (lm75) Tune resolution and sample time per chipJean Delvare2013-05-041-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Most LM75-compatible chips can either sample much faster or with a much better resolution than the original LM75 chip. So far the lm75 driver did not let the user take benefit of these improvements. Do it now. I decided to almost always configure the chip to use the best resolution possible, which also means the longest sample time. The only chips for which I didn't are the DS75, DS1775 and STDS75, because they are really too slow in 12-bit mode (1.2 to 1.5 second worst case) so I went for 11-bit mode as a more reasonable tradeoff. This choice is dictated by the fact that the hwmon subsystem is meant for system monitoring, it has never been supposed to be ultra-fast, and as a matter of fact we do cache the sampled values in almost all drivers. If anyone isn't pleased with these default settings, they can always introduce a platform data structure or DT support for the lm75. That being said, it seems nobody ever complained that the driver wouldn't refresh the value faster than every 1.5 second, and the change made it faster for all chips even in 12-bit mode, so I don't expect any complaint.

With these patches chargers and batteries can now lookup each other without the board files support shim. Rhyland Klein at NVIDIA did the work - New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the AB85xx core and depends on some recent changes to it, so that is why the driver comes through the battery tree. It has an appropriate ack from the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored the driver - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes touch mfd parts, but these were acked by the appropriate MFD maintainer (ie Samuel Ortiz). Lee Jones at Linaro did most of the work and lead the submission process.

| * hwmon: Add ST-Ericsson ABX500 hwmon driverHongbo Zhang2013-04-172-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | Each of ST-Ericsson X500 chip set series consists of both ABX500 and DBX500 chips. This is ABX500 hwmon driver, where the abx500.c is a common layer for all ABX500s, and the ab8500.c is specific for AB8500 chip. Under this designed structure, other chip specific files can be added simply using the same common layer abx500.c.
