iio: ad_sigma_delta: Implement a dedicated reset function

2017-10-12T09:56:11Z

commit 7fc10de8d49a748c476532c9d8e8fe19e548dd67 upstream. Since most of the SD ADCs have the option of reseting the serial interface by sending a number of SCLKs with CS = 0 and DIN = 1, a dedicated function that can do this is usefull.

PATCH] iio: Fix some documentation warnings

2017-08-20T14:21:46Z

The kerneldoc description for the trig_readonly field of struct iio_dev lacked a colon, leading to this doc build warning: ./include/linux/iio/iio.h:603: warning: No description found for parameter 'trig_readonly' A similar issue for iio_trigger_set_immutable() in trigger.h yielded: ./include/linux/iio/trigger.h:151: warning: No description found for parameter 'indio_dev' ./include/linux/iio/trigger.h:151: warning: No description found for parameter 'trig' Fix the formatting and silence the warnings.

Jonathan writes: First set of IIO fixes for the 4.13 cycle. * ad2s1210 - Fix negative angular velocity reads (identified by a gcc 7 warning) * aspeed-adc - Wait for initialization sequence to finish before enabling channels. Without it no channels work. * axp288 - Revert a patch that dropped some bogus register mods. No one is entirely sure why but it breaks charging on some devices. - Fix GPADC pin read returning 0. Turns out a small sleep is needed. * bmc150 - Make sure device is restored to normal state after suspend / resume cycle. Otherwise, simple sysfs reads are broken. * tsl2563 - fix wrong event code. * st-accel - add spi 3-wire support. Needed to fix the lsm303agr accelerometer which only had 3 wires in all cases. Side effect is to enable optional 3-wire support for other devices. * st-pressure - disable multiread by default for LPS22HB (only effects SPI) * sun4i-gpadc-iio - fix unbalanced irq enable / disable * vf610 - Fix VALT slection for REFSEL bits - ensures we are using the right reference pins.

iio: accel: st_accel: add SPI-3wire support

2017-07-06T18:32:29Z

Add SPI Serial Interface Mode (SIM) register information in st_sensor_settings look up table to support devices (like LSM303AGR accel sensor) that allow just SPI-3wire communication mode. SIM mode has to be configured before any other operation since it is not enabled by default and the driver is not able to read without that configuration Whilst a fairly substantial patch, the actual logic is simple and it is better to have the generic fix than a band aid.

iio: add hardware triggered operating mode

2017-06-11T14:58:41Z

Devices, like stm32 timer, could be triggered by hardware events which are not buffer or software events. However it could be necessary to validate the triggers like it is done for buffer or event triggered modes. This patch add a new INDIO_HARDWARE_TRIGGERED operating mode for this kind of devices and allow this mode to register trigger consumer.

Add support for TRGO2 trigger that can be found on STM32F7. Add additional master modes supported by TRGO2. Register additional "tim[1/8]_trgo2" triggers for timer1 & timer8.

iio: sw-device: Fix config group initialization

2017-03-13T20:42:34Z

Use the IS_ENABLED() helper macro to ensure that the configfs group is initialized either when configfs is built-in or when configfs is built as a module. Otherwise software device creation will result in undefined behaviour when configfs is built as a module since the configfs group for the device not properly initialized. Similar to commit b2f0c09664b7 ("iio: sw-trigger: Fix config group initialization").
