Subject: [PATCH 2/2] ARM: dts: zynq: remove the reg property in the pmu
Date: Thu, 23 Apr 2026 22:55:46 -0500	[thread overview]
Message-ID: <20260424035546.646650-2-dinguyen@kernel.org> (raw)
In-Reply-To: <20260424035546.646650-1-dinguyen@kernel.org>

The Cortex-A9 PMU accesses the hardware via system coprocessor registers,
not memory-mapped I/O. The driver does not parse or use a 'reg' property
from the device tree, so we can remove the reg from the DTS.

This change fixes this dtbs_check warning:

(arm,cortex-a9-pmu): 'reg' does not match any of the regexes
