git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging driver tree update from Greg Kroah-Hartman: "Here's the big staging driver tree update for 3.10-rc1 This update contains loads of comedi driver cleanups and fixes in here, iio updates, android driver changes, and other various staging driver cleanups. Thanks to some drivers being removed, and the comedi driver cleanups, we have removed more code than we added: 627 files changed, 65145 insertions(+), 76321 deletions(-) which is always nice to see. All of these have been in linux-next for a while." * tag 'staging-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (940 commits) staging: comedi: ni_labpc: fix legacy driver build staging: comedi: das800: cleanup the cio-das802/16 fifo comments staging: comedi: das800: rename CamelCase vars in das800_ai_do_cmd() staging: comedi: das800: tidy up the private data staging: comedi: das800: tidy up das800_interrupt() staging: comedi: das800: tidy up das800_ai_insn_read() staging: comedi: das800: tidy up das800_di_insn_bits() staging: comedi: das800: tidy up das800_do_insn_bits() staging: comedi: das800: remove extra divisor calculation call staging: comedi: das800: rename {enable,disable}_das800 staging: comedi: das800: tidy up subdevice init staging: comedi: das800: allow attaching without interrupt support staging: comedi: das800: interrupts are required for async command support staging: comedi: das800: tidy up das800_ai_do_cmdtest() staging: comedi: das800: remove 'volatile' on private data variables staging: comedi: das800: cleanup the boardinfo staging: comedi: das800: cleanup range table declarations staging: comedi: das800: introduce das800_ind_{write, read}() staging: comedi: das800: remove forward declarations staging: comedi: das800: move das800_set_frequency() ...

2013-04-07hwmon: (nct6775) Enable both AUXTIN and VIN3 on NCT6776Guenter Roeck1-37/+0
Per datasheet, VIN3 and AUXTIN share the same external pin. However, there is no clean way to detect this condition. Furthermore, both are reported by the BIOS on Supermicro C7H61. It may thus be possible that chip revisions exist where both attributes are supported at the same time. Better play safe and report both. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (ad7314) use spi_get_drvdata() and spi_set_drvdata()Jingoo Han1-2/+2
Use the wrapper functions for getting and setting the driver data using spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we can directly pass a struct spi_device. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Expand scope of supported chipsGuenter Roeck2-13/+12
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.

2013-04-07hwmon: (pmbus/lm25066) Clamp limit attributesGuenter Roeck1-0/+13
Limits on all supported sensors and chips have to be within 0..0x0fff, and limits are always positive. Clamp written values in chip driver. Also clear value cache to ensure that the actually written value is read back and reported correctly. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (pmbus/lm25066) Report VAUX as vmonGuenter Roeck1-52/+21
So far the driver reported the voltage on VAUX as "vout2". This was not entirely appropriate as it is not an output voltage, and complicates the code. Use the new virtual "VMON" register set and report the voltage as "vmon" instead. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (max6697) Use is_visible and sysfs_create_groupGuenter Roeck1-116/+93

2013-04-07hwmon: (pmbus/ltc2978) Code cleanupGuenter Roeck1-11/+14
Use u16 instead of int to store cached limit attributes. This reduces allocated data size per driver instance by 48 bytes. Use defines for the number of pages supported by individual chips. Use ARRAY_SIZE for loops to initialize array variables, and initialize all variables in the same code block. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2013-04-07hwmon: (adt7410) Add support for the adt7310/adt7320Lars-Peter Clausen6-436/+689
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map layout is a bit different, i.e. the register addresses differ between the two variants, but the bit layouts of the individual registers are identical. So both chip variants can easily be supported by the same driver. The issue of non matching register address layouts is solved by a simple look-up table which translates the I2C addresses to the SPI addresses. The patch moves the bulk of the adt7410 driver to a common module that will be shared by the adt7410 and adt7310 drivers. This common module implements the driver logic and uses a set of virtual functions to perform IO access. The adt7410 and adt7310 driver modules provide proper implementations of these IO accessor functions for I2C respective SPI.
