| * Add support for GMT G762/G763 PWM fan controllersArnaud Ebalard2013-06-273-0/+1160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | GMT G762/763 fan speed PWM controller is connected directly to a fan and performs closed-loop or open-loop control of the fan speed. Two modes - PWM or DC - are supported by the chip. Introduced driver provides various knobs to control the operations of the chip (via sysfs interface). Specific characteristics of the system can be passed either using board init code or via DT. Documentation for both the driver and DT bindings are also provided.

| * hwmon: (lm75) Tune resolution and sample time per chipJean Delvare2013-05-041-6/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no standard for the configuration register bits of LM75-like chips. We shouldn't blindly clear bits setting the resolution as they are either unused or used for something else on some of the supported chips. So, switch to per-chip configuration initialization. This will allow for better tuning later, for example using more resolution bits when available. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <linux@roeck-us.net>

New stuff 1) Add OF support for specifying mappings between iio devices and their in kernel consumers. 2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and ad7924 added later in series) 3) Driver for Exynos adc (dt suppor for phy added later in series). 4) Make iio_push_event save IRQ context - necessary if it is to be used within an interrupt handler. Users of this functionality to follow. 5) For iio use the device tree node name to provide the hwmon name attribute if available. Removal and moves out of staging 1) Drop the adt7410 driver from IIO now that there is a hmwon driver with equivalent support. This device is very much targeted at hardware monitoring so hwmon is a more appropriate host for the driver. 2) Move iio_hwmon driver to drivers/hwmon. Cleanups 1) Minor cleanup in ST common library. 2) Large set of patches to break the info_mask element which previously used odd and even bits to specify if a channel attribute was either shared across similar channels or specific to only one. Now we have two bitmaps, one for those parameters that are specific to this channel and one for those shared by all channels with the same type as this one. This has no effect on the userspace abi. It simplifies the core code and provides more space for new channel parameters. It has been on the todo list for a long time! Conflicts: drivers/iio/dac/ad5064.c
| | * | hwmon: Move the IIO client driver for hwmon out of stagingJonathan Cameron2013-03-233-0/+206
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver uses channel maps, defined either through device tree or platform data, to create a hwmon driver which acts as a client for the underlying IIO device channels. Thus a general purpose IIO adc driver can be used to provide hardware monitoring using a subset of its channels. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Guenter Roeck <linux@roeck-us.net> -- The only non move changes here concern the description and changes to the dependencies to IIO explicit and hwmon implicit. I'm proposing moving this into hwmon on the basis of placing drivers based on what they provide rather than what their underlying hardware is. drivers/hwmon/Kconfig | 9 ++ drivers/hwmon/Makefile | 1 + drivers/hwmon/iio_hwmon.c | 196 ++++++++++++++++++++++++++++++++++++++++ drivers/staging/iio/Kconfig | 8 -- drivers/staging/iio/Makefile | 2 - drivers/staging/iio/iio_hwmon.c | 196 ---------------------------------------- 6 files changed, 206 insertions(+), 206 deletions(-)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This ensures that the loop iterations are correct even if/when the number of elements in an array changes. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* | | | hwmon: (nct6775) Enable both AUXTIN and VIN3 on NCT6776Guenter Roeck2013-04-071-37/+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>
* | | | hwmon: (ad7314) use spi_get_drvdata() and spi_set_drvdata()Jingoo Han2013-04-071-2/+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.
