Subject: [PATCH 1/2] dt-bindings: arm: coresight: Add 'power-domains' property
Date: Thu, 21 Jul 2022 15:27:14 -0600	[thread overview]
Message-ID: <20220721212718.1980905-1-robh@kernel.org> (raw)

Coresight components may be in a power domain which is the case for the Arm
Juno board. Allow a single 'power-domains' entry for Coresight components.
