iio: st_sensors: support active-low interrupts

2016-01-10T12:35:32Z

Most ST MEMS Sensors that support interrupts can also handle sending an active low interrupt, i.e. going from high to low on data ready (or other interrupt) and thus triggering on a falling edge to the interrupt controller. Set up logic to inspect the interrupt line we get for a sensor: if it is triggering on rising edge, leave everything alone, but if it triggers on falling edges, set up active low, and if unsupported configurations appear: warn with errors and reconfigure the interrupt to a rising edge, which all interrupt generating sensors support. Create a local header for st_sensors_core.h to share functions between the sensor core and the trigger setup code.

iio: st_sensors: add debugfs register read hook

2015-08-16T09:51:25Z

This adds a debugfs hook to read/write registers in the ST sensors using debugfs. Proved to be awesome help when trying to debug why IRQs do not arrive. Signed-off-by: Linus Walleij Acked-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio: st-sensors: add configuration for WhoAmI address

2015-07-23T19:43:04Z

This patch permits to configure the WhoAmI register address because some device could have not a standard address for this register. Signed-off-by: Giuseppe Barba Reviewed-by: Denis Ciocca Acked-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio: common: ssp_sensors: Add sensorhub driver

2015-01-29T18:49:05Z

Sensorhub is MCU dedicated to collect data and manage several sensors. Sensorhub is a spi device which provides a layer for IIO devices. It provides some data parsing and common mechanism for sensorhub sensors. Adds common sensorhub library for sensorhub driver and iio drivers which uses sensorhub MCU to communicate with sensors.

iio: st_sensors: add devicetree probing support

2014-07-11T20:09:49Z

The I2C devices that make up the STMicroelectronics MEMS sensors may be sneakily enabled by cleverly giving the device node the same name as a string match from the platform device ID table. However the right method is to use the compatible string. On detection, the ST sensors use the ID string to probe and instatiate the right sensor driver, so pass the kernel-internal ID string in the .data field of the OF match table, and set the I2C client name to this name when a compatible match is used. This avoids having misc Linux-specific strings floating around in the device tree. Cc: Lee Jones Cc: Denis CIOCCA Signed-off-by: Linus Walleij Signed-off-by: Jonathan Cameron

iio: st_sensors: move regulator retrieveal to core

2014-04-26T10:52:42Z

Currently the pressure sensor has code to retrieve and enable two regulators for Vdd and Vdd IO, but actually these voltage inputs are found on all of these ST sensors, so move the regulator handling to the core and make sure all the ST sensors call these functions on probe() and remove() to enable/disable power. Here also mover over to obtaining the regulator from the *parent* device of the IIO device, as the IIO device is created on-the-fly in this very subsystem it very unlikely evert have any regulators attached to it whatsoever. It is much more likely that the parent is a platform device, possibly instantiated from a device tree, which in turn have Vdd and Vdd IO supplied assigned to it.

iio: pressure-core: st: Provide support for the Vdd_IO power supply

2013-09-23T19:17:58Z

The power to some of the sensors are controlled by regulators. In most cases these are 'always on', but if not they will fail to work until the regulator is enabled using the relevant APIs. This patch allows for the Vdd_IO power supply to be specified by either platform data or Device Tree. Signed-off-by: Lee Jones Signed-off-by: Jonathan Cameron
