From b5a4c37324049efe0e0199e975e0df9554fa8873 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Thu, 21 Feb 2019 13:34:40 +0800 Subject: [PATCH] dt-bindings: dmaengine: sprd: Change channel id to slave id for DMA cell specifier For Spreadtrum DMA engine, all channels are equal, which means slave can request any channels with setting a unique slave id to trigger this channel. Thus we can remove the channel id from device tree to assign the channel dynamically, moreover we should add the slave id in device tree.
