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