Subject: [PATCH v6 1/2] dt-bindings: dma: snps,dw-axi-dmac: Add fallback compatible for CV1800B
Date: Mon, 11 May 2026 14:38:16 +0800	[thread overview]
Message-ID: <20260511063818.463877-2-inochiama@gmail.com> (raw)
In-Reply-To: <20260511063818.463877-1-inochiama@gmail.com>

The previous version of the binding change only add compatible
string without adding the fallback compatible, this breaks
backward compatibility. Add the needed fallback compatible to
fix this.

Fixes: be3e2a0419c6 ("dt-bindings: dma: snps,dw-axi-dmac: Add CV1800B compatible")
