Jonathan writes: First set of fixes for IIO in the 5.5 cycle. Mixture of old things people have just hit, and a few late breaking issues with things that went in during the merge window. Being sent promptly to resolve potential DT breakage causing issues for binding test builds. * ad7606 - Avoid reading extra data from the device over what was intended. * ad7124 - Enable the internal reference when in use. * ad7292 - Fix up license for newly added binding. Better to not have this go out in a release with more limited header than intended. - Fix a constraint on number of channels. * ad7949 - Fix an issue which can result in readouts being from the wrong channel. * hdc100x - Fix wrong ABI usage (units) for relative humidity channel. * intel mrfld - Allocate right amount of private data (currently allocating too much). * ltc2983 - Avoid a potential issue with machine endianness and wrong length device tree read. * max1027 - Clean up leak of an iio_trigger on probe failure. * max9611 - Ensure we sleep long enough to successfully initialize the sensor. * mpu6050 - Fix wrong ABI usage (units) for temperature channel. * st_accel - Fix an unused variable warning. * st_lsm6dsx - Fix decimation factor issue that can lead to missaligned datasets (and hence garbage) - Fix an issue with how we track enabled fifo channels. - Avoid powering off the device if wake up events are enabled. * tag 'iio-fixes-for-5.5a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: iio: adc: max9611: Fix too short conversion time delay iio: ad7949: fix channels mixups iio: imu: st_lsm6dsx: do not power-off accel if events are enabled iio: imu: st_lsm6dsx: track hw FIFO buffering with fifo_mask iio: imu: st_lsm6dsx: fix decimation factor estimation iio: imu: inv_mpu6050: fix temperature reporting using bad unit iio: humidity: hdc100x: fix IIO_HUMIDITYRELATIVE channel reporting iio: adc: max1027: fix not unregistered iio trigger iio: adc: intel_mrfld_adc: Allocating too much data in probe() iio: adc: ad7124: Enable internal reference dt-bindings: iio: adc: ad7292: fix constraint over channel quantity dt-bindings: iio: adc: ad7292: Update SPDX identifier iio: temperature: ltc2983: fix u32 read into a unsigned long long iio: st_accel: Fix unused variable warning iio: adc: ad7606: fix reading unnecessary data from device

mfd / platform / iio: cros_ec: Register sensor through sensorhub

2019-11-21T10:23:14+00:00

Remove the duplicated code in MFD, since MFD just registers cros-ec-sensorhub if at least one sensor is present. Change IIO cros-ec driver to get the pointer to the cros-ec-dev through cros-ec-sensorhub.

Jonathan writes: First set of IIO fixes for the 5.4 cycle. * adis16400 - Make sure to free memory on a few failure paths. * adxl372 - Fix wrong fifo depth - Fix wrong indexing of data from the fifo. - Perform a reset at startup to avoid a problem with inconsistent state. * axp288 - This is a fix for a fix. The original fix made sure we kept the configuration from some firmwares to preserve a bias current. Unfortunately it appears the previous behaviour was working around a buggy firmware by overwriting the wrong value it had. Hence a regression was seen. * bmc150 - Fix the centre temperature. This was due to an error in one of the datasheets. * hx711 - Fix an issue where a badly timed interrupt could lead to a control line being high long enough to put the device into a low power state. * meson_sar_adc - Fix a case where the irq was enabled before everything it uses was allocated. * st_lsm6dsx - Ensure we don't set the sensor sensitivity to 0 as it will force all readings to 0. - Fix a wait time for the slave i2c controller when the accelerometer is not enabled. * stm32-adc - Precursor for fix. Move a set of register definitions to a header. - Fix a race when several ADCs are in use with some using interrupts to control the dataflow and some using DMA. * vcnl4000 - Fix a garbage of_match_table in which a string was passed instead of the intended enum. * tag 'iio-fixes-for-5.4a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: iio: Fix an undefied reference error in noa1305_probe iio: light: opt3001: fix mutex unlock race iio: adc: ad799x: fix probe error handling iio: light: add missing vcnl4040 of_compatible iio: light: fix vcnl4000 devicetree hooks iio: imu: st_lsm6dsx: fix waitime for st_lsm6dsx i2c controller iio: adc: axp288: Override TS pin bias current for some models iio: imu: adis16400: fix memory leak iio: imu: adis16400: release allocated memory on failure iio: adc: stm32-adc: fix a race when using several adcs with dma and irq iio: adc: stm32-adc: move registers definitions iio: accel: adxl372: Perform a reset at start up iio: accel: adxl372: Fix push to buffers lost samples iio: accel: adxl372: Fix/remove limitation for FIFO samples iio: adc: hx711: fix bug in sampling of data iio: fix center temperature of bmc150-accel-core iio: imu: st_lsm6dsx: forbid 0 sensor sensitivity iio: adc: meson_saradc: Fix memory allocation order

iio: accel: adxl372: Perform a reset at start up

2019-10-09T18:11:25+00:00

We need to perform a reset a start up to make sure that the chip is in a consistent state. This reset also disables all the interrupts which should only be enabled together with the iio buffer. Not doing this, was sometimes causing unwanted interrupts to trigger.

One in two sample sets was lost by multiplying fifo_set_size with sizeof(u16). Also, the double number of available samples were pushed to the iio buffers. Signed-off-by: Stefan Popa Fixes: f4f55ce38e5f ("iio:adxl372: Add FIFO and interrupts support") Cc: Signed-off-by: Jonathan Cameron
