Support new device OKI SEMICONDUCTOR's ML7213 IOH(Input/Output Hub) which is for IVI(In-Vehicle Infotainment) use. The ML7213 is companion chip for Intel Atom E6xx series. The ML7213 is completely compatible for Intel EG20T PCH. Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2010-12-07dma : EG20T PCH: Fix miss-setting DMA descriptorTomoya MORINAGA1-7/+8
Currently, in case of using scatter/gather mode, head of data is not sent to destination. The cause is second descriptor address is set to NEXT. The NEXT must have head of descriptor address. This patch sets head of descriptor address to the NEXT.

2010-08-04DMAENGINE: pch_dma: kill another usage of __raw_{read|write}lYong Wang1-2/+2
Use {read|write}l instead of __raw_{read|write}l since PCH DMA controller is PCI device. Signed-off-by: Yong Wang <yong.y.wang@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2010-08-04dmaengine: Driver for Topcliff PCH DMA controllerYong Wang1-0/+957
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.
