iio:st_pressure: fix sampling gains (bring inline with ABI)

2016-07-27T15:42:20+00:00

commit d43a41152f8e9e4c0d19850884d1fada076dee10 upstream. Temperature channels report scaled samples in Celsius although expected as milli degree Celsius in Documentation/ABI/testing/sysfs-bus-iio. Gains are not implemented at all for LPS001WP pressure and temperature channels. This patch ensures that proper offsets and scales are exposed to userpace for both pressure and temperature channels. Also fix a NULL pointer exception when userspace reads content of sysfs scale attribute when gains are not defined.

iio: convert to common i2c_check_functionality() return value

2016-02-27T17:17:43+00:00

Previously most drivers that used a i2c_check_functionality() check condition required various error codes on failure. This patchset converts to a standard of -EOPNOTSUPP Signed-off-by: Matt Ranostay Signed-off-by: Jonathan Cameron

iio:pressure:ms5611: power regulator support

2016-02-24T20:40:47+00:00

Add support for an optional regulator which, if found into device-tree, will power on device at probing time. The regulator is declared into ms5611 DTS entry as a "vdd-supply" property. Signed-off-by: Gregor Boirie Signed-off-by: Jonathan Cameron

iio:pressure:ms5611: use probed device name

2016-02-24T20:40:46+00:00

Use name of probed device instead of driver's one when registering device. Signed-off-by: Gregor Boirie Signed-off-by: Jonathan Cameron

iio:pressure:ms5611: fix ms5607 temp compensation

2016-02-24T20:40:46+00:00

Computation of sens2 was wrong and is fixed by this patch, sens2 should be: 2 * (t - 2000)^2 See page 8 of ms5607 datasheet here: http://www.meas-spec.com/product/pressure/MS5607-02BA03.aspx Signed-off-by: Gregor Boirie Acked-by: Lucas De Marchi Acked-by: Peter Meerwald-Stadler Signed-off-by: Jonathan Cameron

iio: pressure: ms5611: select IIO_BUFFER

2016-02-17T20:50:01+00:00

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.

Jonathan writes: 2nd round of new IIO device support, features and cleanups for the 4.6 cycle. New Device Support * Apex stx104 DAC - new driver for this PC104 board. Right now DAC support only. * ADI ad5064 - Add support for ad5625, ad5627, ad5645, ad5665, ad5667 DACs. - Add support for Linear Technology ltc2606, ltc2607, ltc2609, ltc2616, ltc2617, ltc2619, ltc2626, ltc2627 and ltc2629. * ADI ad7192 - add support for the ad7193 * Invensense mpu6050 - substantial rework of driver to use regmap allowing SPI support extending the now split driver to cover the MPU6000. * TI adc0832 - new driver supporting ADC0831, ADC0832, ADC0834 and ADC0838 ADCs. * TI ads1015 - new driver, note that there is an existing hwmon driver. The long term intention is to probably remove the hwmon driver but for now we just have guards in place to ensure this driver is not built if that one is enabled. * TI afe4403 - new driver for this heart rate monitor / pulse oximeter front end chip. * TI afe4404 - new driver for this heart rate monitor / pulse oximeter front end chip. Staging Graduations * mxs-lradc - A combined general purpose and touch screen (input) device driver. Originally held in staging to allow reworking into and MFD but as that wasn't happening and isn't an absolute requirement we are moving it out of staging. Driver new features * ms5611 - triggered buffer support - IIO_CHAN_INFO_SCALE to aid the triggered buffer support. Driver cleanups / reworks / fixes * ad5064 - Use an enum for the register map layout to allow support of additional chips (precursor to the new support listed above). - Structural driver changes to allow support of the slightly different handling for the ltc parts above. * ad5933 - drop an exceptional & unnecessary for a function pointer. * ad7606 - Cleanup the repeated copies of pm ops. - consolidate the various channels specs via a sport of rearranging so only one version is needed. * atlas ph sensor - add select IRQ_WORK * hmc8543 (soon to move out of staging) - Comment style fixes - functionality of suspend and resume was swapped. * spear-adc - use devm_clk_dev instead of managing the clk lifetime by hand. Core * Use new dmaengine_terminate_sync call to avoid a theoretical race. * Fix docs for mlock in struct iio_dev as it is correctly taken in some drivers (docs used to say for core only). * Add a helper function for calculating the scan index storage size within the core cutting out some cut and paste versions of the same code.
