2021-05-10iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERAlexandru Ardelean1-1/+0
During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger"), the iio_triggered_buffer_{setup,cleanup}() functions got moved under the hid-sensor-trigger module. The above change works fine, if any of the sensors get built. However, when only the common hid-sensor-trigger module gets built (and none of the drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced. Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets selected. All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

2021-01-10iio: magnetometer: Add driver for Yamaha YAS530Linus Walleij1-0/+15
This adds an IIO magnetometer driver for the Yamaha YAS530 family of magnetometer/compass chips YAS530, YAS532 and YAS533. A quick survey of the source code released by different vendors reveal that we have these variants in the family with some deployments listed: * YAS529 MS-3C (2005 Samsung Aries) * YAS530 MS-3E (2011 Samsung Galaxy S Advance) * YAS532 MS-3R (2011 Samsung Galaxy S4) * YAS533 MS-3F (Vivo 1633, 1707, V3, Y21L) * (YAS534 is a magnetic switch) * YAS535 MS-6C * YAS536 MS-3W * YAS537 MS-3T (2015 Samsung Galaxy S6, Note 5) * YAS539 MS-3S (2018 Samsung Galaxy A7 SM-A750FN) The YAS529 is so significantly different from the YAS53x variants that it will require its own driver. The YAS537 and YAS539 have slightly different register sets but have strong similarities so a common driver patching this one will probably be reasonable. The source code for Samsung Galaxy A7's YAS539 is not that is significantly different from the YAS530 in the Galaxy S Advance, so I believe we will only need this one driver with quirks to handle all of them. The YAS539 is actively announced on Yamaha's devices site: https://device.yamaha.com/en/lsi/products/e_compass/ This is a driver written from scratch using buffered IIO and runtime PM handling regulators and reset. Thanks to Andy Shevchenko for great help in finding all the special kernel infrastructure functions and quirks during review of this driver.

2016-08-15iio: magn: add a driver for AK8974Linus Walleij1-1/+15
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.

2014-06-16iio: AK09911 : 3 axis compass supportSrinivas Pandruvada1-0/+10
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 <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
