2016-08-21iio: hid-sensors: use asynchronous resumeSrinivas Pandruvada2-1/+22
Some platforms power off sensor hubs during S3 suspend, which will require longer time to resume. This hurts system resume time, so resume asynchronously. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-08-21iio: adc: mt2701: Add Mediatek auxadc driver for mt2701.Zhiyong Tao3-0/+305
Add Mediatek auxadc driver based on iio. It will register a device in iio and support iio. So thermal can read auxadc channel to sample data by iio device. It is tested successfully on mt2701 platform. Mt8173 and mt6577 platforms are not tested. But the expectation is compatible.

2016-08-21dt-bindings: auxadc: Add binding document for Mediatek auxadc.Zhiyong Tao2-21/+29
The commit adds the device tree binding documentation for the mediatek auxadc found on Mediatek MT2701. Thermal gets auxadc sample data by iio device. So the commit changes auxadc device tree binding documentation from /soc/mediatek/auxadc.txt to /iio/adc/mt6577_auxadc.txt.

2016-08-15iio: magn: add a driver for AK8974Linus Walleij4-1/+886
This adds a driver for the Asahi Kasei AK8974 and its sibling AMI305 magnetometers. It was deployed on scale in 2009 on a multitude of devices. It is distincly different from AK8973 and AK8975 and needs its own driver. This patch is based on the long lost work of Samu Onkalo at Nokia, who made a misc character device driver for the Maemo/MeeGo Nokia devices, before the time of the IIO subsystem. It was mounted in e.g. the Nokia N950, N8, N86, N97 etc. It is also mounted on the ST-Ericsson HREF reference designs. It works nicely in sysfs: $ cat in_magn_x_raw && cat in_magn_y_raw && cat in_magn_z_raw -55 -101 161 And with buffered reads using a simple HRTimer trigger: $ generic_buffer -c10 -a -n ak8974 -t foo iio device number being used is 3 iio trigger number being used is 2 No channels are enabled, enabling all channels Enabling: in_magn_x_en Enabling: in_magn_y_en Enabling: in_magn_z_en Enabling: in_timestamp_en /sys/bus/iio/devices/iio:device3 foo -58.000000 -102.000000 157.000000 946684970985321044 -60.000000 -98.000000 159.000000 946684971012237548 -60.000000 -106.000000 163.000000 946684971032257080 -62.000000 -94.000000 169.000000 946684971052185058 -58.000000 -98.000000 163.000000 946684971072204589 -54.000000 -100.000000 163.000000 946684971092224121 -53.000000 -103.000000 164.000000 946684971112731933 -50.000000 -102.000000 165.000000 946684971132232666 -61.000000 -101.000000 164.000000 946684971152191162 -57.000000 -99.000000 168.000000 946684971172210693 Disabling: in_magn_x_en Disabling: in_magn_y_en Disabling: in_magn_z_en Disabling: in_timestamp_en I cannot currently scale these raw values to gauss. This is because of lack of documentation. I have sent a request for a datasheet to Asahi Kasei. The driver can optionally use a DRDY line IRQ to capture data, else it will sleep and poll.

2016-07-24iio: Add IIO support for the Measurement Computing CIO-DAC familyWilliam Breathitt Gray4-0/+160
The Measurement Computing CIO-DAC is a family of 16-bit and 12-bit analog output devices. The analog outputs are from AD660BN/AD7237 converters with each output buffered by an OP-27. Voltage ranges are configured via physical jumpers on the device. This driver does not support the devices' simulataneous update mode; the XFER jumper option should be deselected for all analog output channels. This driver provides IIO support for the Measurement Computing CIO-DAC family: CIO-DAC16, CIO-DAC08, and PC104-DAC06. The base port addresses for the devices may be configured via the base array module parameter.
