iio: hmc5843: Move hmc5843 out of staging

2016-02-24T20:40:39Z

This patch moves hmc5843 driver from staging/iio/magnetometer to iio/magnetometer, updates the corresponding Makefiles and moves the hmc5843* entries to the 'Industrial I/O support -> Magnetometer sensors' menu. Signed-off-by: Cristina Moraru Cc: Daniel Baluta Signed-off-by: Jonathan Cameron

iio: hmc5843: Add attributes for measurement config of bias current

2016-02-21T20:22:21Z

Change static attribute meas_conf for bias current configuration to channel attribute in_magn_meas_conf and also add in_magn_meas_conf_available attribute to view available configurations. This patch solves functionality bug: driver was using same function hmc5843_set_measurement_configuration for setting bias current config for all device types but the function was returning -EINVAL for any setting >= 0x03 although, for sensor HMC5983, value 3 is valid. API for setting bias measurement configuration: normal - Normal measurement configuration (default): In normal measurement configuration the device follows normal measurement flow. Pins BP and BN are left floating and high impedance. positivebias - Positive bias configuration: In positive bias configuration, a positive current is forced across the resistive load on pins BP and BN. negativebias - Negative bias configuration. In negative bias configuration, a negative current is forced across the resistive load on pins BP and BN. disabled - Only available on HMC5983. Magnetic sensor is disabled. Temperature sensor is enabled. Signed-off-by: Cristina Moraru Cc: Daniel Baluta Signed-off-by: Jonathan Cameron

spi: Drop owner assignment from spi_drivers

An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis Acked-by: Jonathan Cameron Signed-off-by: Mark Brown

staging: iio: hmc5843: Export missing SPI module alias information

2015-08-22T17:51:18Z

The SPI core always reports the MODALIAS uevent as "spi:" regardless of the mechanism that was used to register the device (i.e: OF or board code) and the table that is used later to match the driver with the device (i.e: SPI id table or OF match table). So drivers needs to export the SPI id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added.

staging: iio: hmc5843: Set iio name dynamically

2015-08-16T09:51:27Z

Load the driver using the below command: echo hmc5983 0x1e > /sys/bus/i2c/devices/i2c-?/new_device In sysfs, the iio name is hmc5843, however the i2c name is hmc5983, they are inconsistent. With this patch, the iio name will be the same as the i2c device name Signed-off-by: Yong Li Reviewed-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron
