Hi,

This series adds support for ARM SCMI Protocol based IIO Device.

This driver provides support for Accelerometer and Gyroscope sensor using
SCMI Sensor Protocol extensions added in the SCMIv3.0 ARM specification,
which is available at 

https://developer.arm.com/documentation/den0056/c/

This version of the patch series has been tested using 
version 5.4.21 branch of Android common kernel.

Any feedback welcome,

Thanks,

Jyoti Bhayana

v6 --> v7
- Fixed the error reported by kernel test robot

v5 --> v6
- Fixed the warning by kernel test robot
- Incorporated the feedback comments from v5
- Fixed the bug found in scmi_iio_set_odr_val
  for calculating the multiplier

v4 --> v5
- Dropped the RFC tag
- Added channel ext_info for raw_available
- Incorporated the feedback comments from v4 review of the patch

v3 --> v4
- Incorporated the feedback comments from v3 review of the patch

v2 --> v3
- Incorporated the feedback comments from v2 review of the patch

v1 --> v2
- Incorporated the feedback comments from v1 review of the patch
- Regarding the new ABI for sensor_power,sensor_max_range,
and sensor_resolution, these are some of the sensor attributes
which Android passes to the apps. If there is any other way of getting
those values, please let us know
