2018-09-07regmap: split up regmap_config.use_single_rwDavid Frey
Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write. No attempt was made to evaluate whether it is possible to set only one of use_single_read or use_single_write.

2017-04-02hwmon: (lm75) Add OF device ID tableJavier Martinez Canillas
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

2015-08-03thermal: consistently use int for temperaturesSascha Hauer
The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.

2014-11-20thermal: of: improve of-thermal sensor registration APIEduardo Valentin
Different drivers request API extensions in of-thermal. For this reason, additional callbacks are required to fit the new drivers needs. The current API implementation expects the registering sensor driver to provide a get_temp and get_trend callbacks as function parameters. As the amount of callbacks is growing, this patch changes the existing implementation to use a .ops field to hold all the of thermal callbacks to sensor drivers. This patch also changes the existing of-thermal users to fit the new API design. No functional change is introduced in this patch.

2013-12-04hwmon: lm75: expose to thermal fw via DT nodesEduardo Valentin
This patch adds to lm75 temperature sensor the possibility to expose itself as thermal zone device, registered on the thermal framework. The thermal zone is built only if a device tree node describing a thermal zone for this sensor is present inside the lm75 DT node. Otherwise, the driver behavior will be the same. Note: This patch has also been reviewed by Jean D. He has requested to perform a wider inspection of possible users of thermal and hwmon interaction API. On the other hand, the change on this patch is acceptable on first step of overall code change.

2013-05-04hwmon: (lm75) Tune resolution and sample time per chipJean Delvare
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.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.
