Subject: [RFC PATCH v2 0/1] Adding support for IIO SCMI based sensors

Hi,

This series adds support for ARM SCMI Protocol based IIO Device.
This driver provides support for Accelerometer and Gyroscope sensor
using new SCMI Sensor Protocol defined by the upcoming SCMIv3.0 ARM
specification, which is available at 

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

The series is currently based on top of:

commit f83eb664cdb4 ("Merge tag 'scmi-voltage-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into for-next/scmi")

in Sudeep for-next/scmi branch:

https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/\
linux.git/log/?h=for-next/scmi

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

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
