From c3635c78e500a52c9fcd55de381a72928d9e054d Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 26 Mar 2010 16:44:01 -0700 Subject: DMAENGINE: generic slave control v2 Convert the device_terminate_all() operation on the DMA engine to a generic device_control() operation which can now optionally support also pausing and resuming DMA on a certain channel. Implemented for the COH 901 318 DMAC as an example.
