Subject: [PATCH v2 1/3] dt-bindings: dma: snps,dw-axi-dmac: Add reset items
Date: Tue, 21 Feb 2023 22:04:22 +0800 [thread overview]
Message-ID: <20230221140424.719-2-walker.chen@starfivetech.com> (raw)
In-Reply-To: <20230221140424.719-1-walker.chen@starfivetech.com>
This DMA controller needs to be reset before being used on JH7110 SoC,
so add reset items to support this chip.
