2017-08-22iio:proximity: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron1-2/+0
The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2017-08-18iio: srf08: add support for srf02 in i2c modeAndreas Klinger1-18/+63
srf02 added with support for i2c interface Attributes for setting max range or sensitivity are omitted for the case of srf02 type sensor, because they are not supported by the hardware. Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2017-08-18iio: srf08: add sensor type srf10Andreas Klinger1-15/+75
Ultrasonic sensor srf10 is quite similar to srf08 and now also supported by the driver as device tree compatible string. It was necessary to prepare the source for supplementary sensors. This is done by enum srf08_sensor_type. The most significiant difference between srf08 and srf10 is another range and values of register gain (in the driver it's call sensitivity). Therefore the array of it is extended and dependent of the sensor type. Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2017-08-18iio: srf08: add triggered buffer supportAndreas Klinger1-3/+57
Add support for triggered buffers. Data format is quite simple: distance 16 Bit alignment 48 Bit timestamp 64 Bit Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2017-08-18iio: srf08: add device tree tableAndreas Klinger1-0/+8
Added MODULE_DEVICE_TABLE for device tree bindings. It used to work without it by using the i2c_device_id table, but adding the table makes everything clear and documented. Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2017-01-28iio: distance: srf08: add IIO driver for us rangerAndreas Klinger1-0/+398
This is the IIO driver for devantech srf08 ultrasonic ranger which can be used to measure the distances to an object. The sensor supports I2C with some registers. Supported Features include: - read the distance in ranging mode in centimeters - output of the driver is directly the read value - together with the scale the driver delivers the distance in meters - only the first echo of the nearest object is delivered - set sensitivity as analog value in the range of 0-31 means setting gain register on device - set range registers; userspace enters max. range in millimeters in 43 mm steps Features not supported by this driver: - ranging mode in inches or in microseconds - ANN mode - change I2C address through this driver - light sensor The driver was added in the directory "proximity" of the iio subsystem and the menu in den config is now called "Proximity and distance sensors" Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
