From d9cb0a4c0be595b55e30cf8774d3e92ab38bca5b Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 3 May 2022 08:54:05 +0200 Subject: dmaengine: pxa: deprecate '#dma-channels' and '#dma-requests' The generic properties, used in most of the drivers and defined in generic dma-common DT bindings, are 'dma-channels' and 'dma-requests'. Switch to new properties while keeping backward compatibility.
