* iio: hid-sensor-gyro-3d: Fix return valuesSachin Kamat2014-07-05
| | | | | | | | | | | | IIO_CHAN_INFO_SAMP_FREQ and IIO_CHAN_INFO_HYSTERESIS cases ignored the actual return values (which could be -EINVAL) and instead returned IIO_VAL_INT_PLUS_MICRO always. Return the actual value obtained from the functions. Both functions return IIO_VAL_INT_PLUS_MICRO upon success.

* iio: hid-sensors: Gyro 3D: Raw read supportSrinivas Pandruvada2014-05-05

* iio: hid-sensors: Add API to power on/offSrinivas Pandruvada2014-05-05
| | | | | | | | | Added an API to allow client drivers to turn ON and OFF sensors for quick read. Added data_read as counting varaible instead of boolean, so that sensor is powered off only when last user released it.

* iio: st_sensors: move regulator retrieveal to coreLinus Walleij2014-04-26
| | | | | | | | | | | | | | | | | | | | 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:gyro: bug on L3GD20H gyroscope supportDenis CIOCCA2014-02-18
| | | | | | | | | | | The driver was not able to manage the sensor: during probe function and wai check, the driver stops and writes: "device name and WhoAmI mismatch." The correct value of L3GD20H wai is 0xd7 instead of 0xd4. Dropped support for the sensor.

| * iio: hid_Sensors: fix crash during trigger unregisterSrinivas Pandruvada2013-11-02
| | | | | | | | | | | | | | | | | | | | | | We can't store the trigger instance created by iio_trigger_alloc, in trig field of iio_device structure. This needs to be stored in the driver private data. Othewise it can result in crash during module unload. Hence created a trig_ptr in the common data structure for each HID sensor IIO driver and storing here.
