Subject: [PATCH] perf/marvell: cn10k_tad: Publish the OF module alias
Date: Sat, 5 Sep 2026 21:43:17 +0800 [thread overview]
Message-ID: <20260905134317.67317-1-hppiscas@163.com> (raw)
The TAD PMU platform driver has ACPI and OF match tables, but only
the ACPI table is published. A Device Tree platform device emits an
OF modalias, so the ACPI alias does not select this module for it.
Publish the OF table inside CONFIG_OF and retain ACPI support.
Fixes: 036a7584bede ("drivers: perf: Add LLC-TAD perf counter support")
