Subject: [PATCH 6/6] dt-bindings: fsi: Convert aspeed,ast2400-cf-fsi-master to DT schema
Date: Thu, 31 Jul 2025 17:12:23 -0500	[thread overview]
Message-ID: <20250731-dt-fsi-cleanups-v1-6-e7b695a29fc3@kernel.org> (raw)
In-Reply-To: <20250731-dt-fsi-cleanups-v1-0-e7b695a29fc3@kernel.org>

Convert the ASpeed Coldfire offloaded GPIO FSI master.

Drop the "fsi-master" compatible as it has not be used consistently and
doesn't represent anything.
