Subject: [PATCH v2 09/11] cpufreq: scmi: Add support to parse domain-id using #power-domain-cells
Date:   Thu, 13 Jul 2023 16:17:36 +0200

The performance domain-id can be described in DT using the power-domains
property or the clock property. The latter is already supported, so let's
add support for the power-domains too.
