Subject: [PATCH v3 4/6] ARM: dts: am33xx: use new 'dma-channels/requests' properties
Date: Tue, 3 May 2022 08:51:59 +0200 [thread overview]
Message-ID: <20220503065201.51818-5-krzysztof.kozlowski@linaro.org> (raw)
In-Reply-To: <20220503065201.51818-1-krzysztof.kozlowski@linaro.org>
The '#dma-channels' and '#dma-requests' properties were deprecated in
favor of these defined by generic dma-common DT bindings. Add new
properties while keeping old ones for backwards compatibility.
