Subject[PATCH 00/15] 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 hwmon and 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
