hwmon: (lm75) Add support for the Dallas/Maxim DS7505

2013-05-04T12:49:36+00:00

Basically it's the same as the original DS75 but much faster.

hwmon: (lm75) Tune resolution and sample time per chip

2013-05-04T12:49:36+00:00

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.

Merge tag 'for-v3.10' of git://git.infradead.org/battery-2.6

2013-04-30T22:15:24+00:00

Pull battery updates from Anton Vorontsov:
 "Highlights:

   - OpenFirmware/DeviceTree support for the Power Supply core: the core
     now automatically populates supplied_from hierarchy from the device
     tree.  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.

  Minor changes, but still worth mentioning:

   - Battery temperature reporting fix for Nokia N900 phones
   - Versatile Express poweroff driver moved into drivers/power/reset/
   - Tree-wide: use devm_kzalloc() where appropriate
   - Tree-wide: dev_pm_ops cleanups/fixes"

hwmon: Add ST-Ericsson ABX500 hwmon driver

2013-04-17T01:27:52+00:00

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.

hwmon: (nct6775) Expand scope of supported chips

2013-04-08T04:16:42+00:00

NCT6775, NCT6776, and NCT6779 have a number of variants with the same
chip ID but different chip labels. Add text "or compatible" to the
message displayed when the driver is loaded and rephrase the Kconfig
entry to reflect that it also supports compatible chips.
