iio: magn: add a driver for AK8974

2016-08-15T15:49:39Z

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.

iio: magn: Split bmc150 driver in common/i2c parts

2016-04-18T19:44:40Z

This is useful for easily adding SPI support in later patches. Now bmc150_magn exports core functions to be used by I2C/SPI drivers instances. For the moment only I2C driver is supported. Signed-off-by: Daniel Baluta Acked-by: Irina Tirdea Signed-off-by: Jonathan Cameron

iio: magn: Add support for BMC150 magnetometer

2015-05-10T19:31:43Z

Add support for the Bosh BMC150 Magnetometer. The specification can be downloaded from: http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-04.pdf. The chip contains both an accelerometer and a magnetometer. This patch adds support only for the magnetometer part. The temperature compensation formulas are based on bmm050_api.c authored by contact@bosch.sensortec.com. Signed-off-by: Irina Tirdea Signed-off-by: Jonathan Cameron

iio: AK09911 : 3 axis compass support

2014-06-16T19:55:24Z

Added IIO magnetometer driver for AK09911. In functionality is resembles AK8975 or AK8963. But there are several differences, so instead of modifying existing AK8975 driver and keep it clean, implemented as a separate driver. The key differences are: - Register map is different and have different indexes - AK09911 is a very compact interface with no DRDY pin. So no support of interrupt or GPIO poll - Even for polled mode no mention on ST2 register, which is required in ak8975 driver - mode values are different for fuse access Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron
