Linus Walleij 2d7768a872 iio: st_sensors: add devicetree probing support
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.

Denis CIOCCA a065771641 iio:gyro: bug on L3GD20H gyroscope support
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.

Denis CIOCCA 23cde4d65c iio: Added ST-sensors platform data to select the DRDY interrupt pin
This patch add support to redirect the DRDY interrupt on INT1 or INT2
on accelerometer and pressure sensors.

Jonathan Cameron 8ce4a56a52 iio:st_sensors fix build when !CONFIG_IIO_TRIGGER
Partly a case of removing unused headers and partly a case
of ifdefing out the iio_trigger_ops structures.  This has
come about because of an 'unusual' separation of code in this
driver.
