Subject: [PATCH] dt-bindings: arm: cci: Allow syscon fallback
Date: Mon, 21 Sep 2026 18:28:26 -0500 [thread overview]
Message-ID: <20260921232827.3138193-1-robh@kernel.org> (raw)
Allow ARM CCI-400 slave interface nodes to use a syscon fallback
compatible. The MT7622 DTS uses the fallback on cci_control2 while
keeping arm,cci-400-ctrl-if as the primary compatible.
