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. In order to achieve that, let us extend the scmi bus to match based not only protocol id but also the scmi device name if one is available.

To avoid open-coding, let's introduce of_get_cpu_state_node(), which takes the device node for the CPU and the index to the requested idle state node, as in-parameters. In case a corresponding idle state node is found, it returns the node with the refcount incremented for it, else it returns NULL. Moreover, for PSCI there are two options to describe the CPU's idle states [1], either via a flattened description or a hierarchical layout. Hence, let's take both options into account.
