Subject: [PATCH v2 2/5] cpufreq: scmi-cpufreq: Log number of perf domains
Date: Wed, 13 May 2026 10:16:55 -0700	[thread overview]
Message-ID: <20260513-scmi-client-probe-log-v2-2-36607e9dd540@oss.qualcomm.com> (raw)
In-Reply-To: <20260513-scmi-client-probe-log-v2-0-36607e9dd540@oss.qualcomm.com>

The SCMI cpufreq driver does not currently log the number of performance
domains discovered from firmware. This information is useful for
confirming the firmware exposed performance domains during debugging.

Log the domain count after a successful probe to align with the existing
SCMI client driver logging pattern.
