From a074ae38f859b90bd259f5df43784834b44412d1 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 9 Apr 2015 12:35:49 +0300 Subject: dmaengine: Add driver for TI DMA crossbar on DRA7x The DRA7x has more peripherals with DMA requests than the sDMA can handle: 205 vs 127. All DMA requests are routed through the DMA crossbar, which can be configured to route selected incoming DMA requests to specific sDMA request.
