2016-02-21iio: hmc5843: Add attributes for measurement config of bias currentCristina Moraru1-46/+87
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 <cristina.moraru09@gmail.com> Cc: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-02-19iio: chemical: atlas-ph-sensor: switch regmap cacheMatt Ranostay1-3/+1
switch from using REGCACHE_FLAT to REGCACHE_RBTREE so initial hw values are read from device. This also allows some volatile ranges to be dropped. Note that REGCACHE_FLAT is intended only for very low lag cases so doesn't do nice things like read initial values from the device. Hence this change.

2016-02-17iio: pressure: ms5611: select IIO_BUFFERArnd Bergmann1-0/+1
The ms5611 driver started using the IIO_TRIGGERED_BUFFER infrastructure which in turn depend on IIO_BUFFER, and it produces a build error now if that is not enabled: warning: (... && MS5611 && ...) selects IIO_TRIGGERED_BUFFER which has unmet direct dependencies (IIO && IIO_BUFFER) buffer/industrialio-triggered-buffer.c: In function 'iio_triggered_buffer_setup': buffer/industrialio-triggered-buffer.c:58:2: error: implicit declaration of function 'iio_device_attach_buffer' [-Werror=implicit-function-declaration] pressure/ms5611_core.c: In function 'ms5611_trigger_handler': pressure/ms5611_core.c:193:2: error: implicit declaration of function 'iio_push_to_buffers_with_timestamp' [-Werror=implicit-function-declaration] This adds the second select.

2016-02-17iio: health/afe4404: mark suspend/resume functions __maybe_unusedArnd Bergmann1-2/+2
The newly added afe4404 driver implements suspend/resume using the SIMPLE_DEV_PM_OPS() macro, which leaves out references to the actual functions when CONFIG_PM is disabled, causing a harmless warning: health/afe4404.c:509:12: error: 'afe4404_suspend' defined but not used health/afe4404.c:530:12: error: 'afe4404_resume' defined but not used This marks the functions as __maybe_unused so we don't get those warnings.

2016-02-17iio: health/afe4403: select REGMAP_SPIArnd Bergmann1-0/+1
The newly added afe4403 driver uses the regmap facility to abstract the I2C and SPI access. However, it fails to ensure that regmap_spi is actually present: drivers/iio/built-in.o: In function `afe4403_probe': :(.text+0x9bf8): undefined reference to `__devm_regmap_init_spi' This adds a Kconfig select statement like the afe4404 I2C driver has.

The return value of devm_kzalloc on failure of allocation of memory should be -ENOMEM and not -1. Found using Coccinelle. A simplified version of the semantic patch used is: //<smpl> @@ expression *e; @@ e = devm_kzalloc(...); if (e == NULL) { ... return - -1 + -ENOMEM ; } //</smpl> The single call site does not perform any checks on the return value, hence no change is required at the call site.

2016-02-15staging: gdm724x: gdm_mux: Remove create_workqueue()Amitoj Kaur Chawla1-15/+3
With concurrency managed workqueues, use of dedicated workqueues can be replaced by using system_wq. Drop mux_rx_wq by using system_wq. Since there is only one work item per mux_dev and different mux_devs do not need to be ordered, increase of concurrency level by switching to system_wq should not break anything. cancel_work_sync() is used to ensure that work is not pending or executing on any CPU. Lastly, since all devices are suspended, which shutdowns the work item before the driver can be unregistered, it is guaranteed that no work item is pending or executing by the time exit path runs.
