Subject[PATCH v2 00/11] firmware: arm_scmi: Add support for multiple device per protocol
Date
Currently only one scmi device is created for each protocol enumerated.
However, there is requirement to make use of some procotols by multiple
kernel subsystems/frameworks. One such example is SCMI PERFORMANCE
protocol which can be used by both cpufreq and devfreq drivers.
Similarly, SENSOR protocol may be used by either hwmon or iio subsystems,
and POWER protocol may be used by genpd and regulator drivers.

This series adds support for multiple device per protocol using scmi device
name if one is available. It also updates existing drivers to add
scmi device names to driver id tables.

Regards,
Sudeep

v1[1]->v2:
- Dropped all the changes that mixes up the device specific init
with the protocol
- Used idr_replace to skip protocol initialisation as suggested
- Added collected reviewed/acked-by
- Reworded hwmon changes to reflect that hwmon/iio drivers will
be mutually exclusive and hwmon needs to be removed if IIO
support is added
