Because IIO_EV_DIR_* are not bitmasks but enums,
IIO_EV_DIR_RISING | IIO_EV_DIR_FALLING is not equal
with IIO_EV_DIR_EITHER.This could lead to potential misformatted sysfs attributes
like:
* in_accel_x_thresh_(null)_en
* in_accel_x_thresh_(null)_period
* in_accel_x_thresh_(null)_valueor even memory corruption.

the BMA250 has only 10-bit resolution; while the data readout registers
have identical layout, the configuration is completely different compared
to the BMA180datasheet: http://ae-bst.resource.bosch.com/media/products/dokumente/bma250/BST-BMA250-DS002-05.pdf

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

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.

If touchscreen mode is enabled and a conversion is requested on another
channel, the result in the last converted data register can be a
touchscreen relative value. Starting a conversion involves to do a
conversion for all active channel. It starts with ADC channels and ends
with touchscreen channels. Then if ADC_LCD register is not read quickly,
its content may be a touchscreen conversion.
To remove this temporal constraint, the conversion value is taken from
the channel data register.Signed-off-by: Ludovic Desroches

The following chips are either similar or have only the resolution
different. Hence, change this driver to support these chips too:BMI055 - combo chip (accelerometer part is identical to BMC150's)
BMA255 - identical to BMC150's accelerometer
BMA222E - 8 bit resolution
BMA250E - 10 bit resolution
BMA280 - 14 bit resolutionAdditionally:
* add bmc150_accel_match_acpi_device() function to check that the device
has been enumerated through ACPI;
* rename bmc150_accel_acpi_gpio_probe() to bmc150_accel_gpio_probe()
since the ACPI matching has been moved to the new function. Also, this
will allow for the GPIO matching to be done against a device tree too, not only
ACPI tree;
* rename bmc150_scale_info struct member 'range' to 'reg_range' to be
consistent with the naming convention used elsewhere in the driver
and declare it u8, instead of int;
* change CONFIG description to list all supported chips;Signed-off-by: Laurentiu Palcu

When CONFIG_PM_RUNTIME is not set, the following issues are seen:
* warning message at compilation time:
warning: 'bmc150_accel_get_startup_times' defined but not used [-Wunused-function]
* bmc150_accel_set_power_state() will always fail and reading the
accelerometer data is impossible;
This occurs because of the call to pm_runtime_put_autosuspend calls
__pm_runtime_suspend which returns -ENOSYS.This commit fixes these.

Value from st_sensors_set_drdy_int_pin() is assigned to err here,
but that stored value is not used before it is overwritten. To fix
this we're enforcing a check on st_sensors_set_drdy_int_pin()'s
return value and if it's an error, we're returning right away.Cc: jic23@kernel.org
