Hi Jonathan,
Instead of IIO_VAL_INT_PLUS_MICRO, we can also use IIO_VAL_FRACTIONAL
right for the raw values for min/max range and resolution? But, to
keep things simple though, it will be nice if the IIO driver uses
IIO_VAL_INT and throws an error if there is a negative exponent in the
following

As you've id
Hi Jonathan,
Can you clarify one thing ? If we go with option 2 which is using
IIO_AVAIL_RANGE for min,step,high using IIO_VAL_INT then how will it
ensure the possible floating value for step as we are using int type?
Thanks,
Jyoti

Hi Jonathan,
I know it is a bit confusing. Let me try to explain it with some
examples to hopefully clarify some things here.
SCMI Platform talks to the native/actual sensor, gets the raw values
from the native sensor and applies the scale and then sends those
values to the SCMI agent and the SCMI

Hi Jonathan,
In section 4.7.2.5.1 of the specification, the following exponent is
the scale value
uint32 axis_attributes_high
Bits[15:11] Exponent: The power-of-10 multiplier in two’s-complement
format that is applied to the sensor unit
specified by the SensorType field.
and the resolution is

Hi Jonathan,
Instead of adding IIO_VAL_INT_H32_L32, I am thinking of adding
IIO_VAL_FRACTIONAL_LONG
or IIO_VAL_FRACTIONAL_64 as the scale/exponent used for min/max range can be
different
than the one used in resolution according to specification.
I am planning to use read_avail for IIO_CHAN_IN

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
