Add support for the BMI055 gyroscope sensor. BMI055 is a package
consisting of an acceleration sensor and a gyroscope. This patch
adds support for the gyroscope only.Spec downloaded from:
http://ae-bst.resource.bosch.com/media/products/dokumente/bmi055/BST-BMI055-DS000-06.pdfThe BMI055 gyroscope uses the same register definition as BMG160,
but does not specify a temp register. However, the temp register
seems to be working in the same way as for BMG160, so this patch
does not remove the temp channel for BMI055.Signed-off-by: Irina Tirdea

Signed-off-by: Jonathan Cameron -
When CONFIG_PM_RUNTIME is not defined and bmg160 tries to power
off the device, bmg160_set_power_state will call pm_runtime_put_autosuspend,
which is not implemented (wil return -ENOSYS).Only call bmg160_set_power_state when CONFIG_PM_RUNTIME is defined.

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

By using the info_mask_shared_by_all element of the channel spec, acce
to the sampling frequency becomes available to in kernel users of the
driver. It also shortens and simplifies the code.This particular conversion was made more complicated by the shared library
and the fact that a number of the drivers do not actually have support for
setting or reading the sampling frequency. The hardware, in those cases
investigated supports it. It's just never been implemented.Signed-off-by: Jonathan Cameron

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.Cc: Lee Jones

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.Signed-off-by: Srinivas Pandruvada
