Subject: [PATCH v2 1/2] dt-bindings: dma: apple,admac: Add M3 generation ADMACs
Date: Wed, 29 Jul 2026 13:46:34 +0200 [thread overview]
Message-ID: <20260729-t603x-admac-v2-1-e4b2bb6ca45e@chaosmail.tech> (raw)
In-Reply-To: <20260729-t603x-admac-v2-0-e4b2bb6ca45e@chaosmail.tech>
The admacs seen in M3-generation SoCs (t603x, t8122) need additional
configuration writes and so are getting a new compatible chain.
Acked-by: Rob Herring (Arm) <robh@kernel.org>
