From 0c42bd0e425e9c8ddb7019fc446f7d915e36c5f6 Mon Sep 17 00:00:00 2001 From: Yong Wang Date: Fri, 30 Jul 2010 16:23:03 +0800 Subject: dmaengine: Driver for Topcliff PCH DMA controller Topcliff PCH is the platform controller hub that is going to be used in Intel's upcoming general embedded platforms. This adds the driver for Topcliff PCH DMA controller. The DMA channels are strictly for device to host or host to device transfers and cannot be used for generic memcpy.
