From 67eacc1583909d0588c8d5d80c16298c899a6382 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Tue, 18 Jun 2013 18:16:57 +0200 Subject: DMA: shdma: add DT support This patch adds Device Tree support to the shdma driver. No special DT properties are used, only standard DMA DT bindings are implemented. Since shdma controllers reside on SoCs, their configuration is SoC-specific and shall be passed to the driver from the SoC platform data, using the auxdata procedure.
