Subject: [PATCH v2 3/3] arm64: dts: sprd: use new 'dma-channels' property
Date: Tue, 3 May 2022 08:51:47 +0200 [thread overview]
Message-ID: <20220503065147.51728-4-krzysztof.kozlowski@linaro.org> (raw)
In-Reply-To: <20220503065147.51728-1-krzysztof.kozlowski@linaro.org>
The '#dma-channels' property was deprecated in favor of one defined by
generic dma-common DT bindings. Add new property while keeping old one
for backwards compatibility.
