2010-10-07intel_mid_dma: change the slave interfaceKoul, Vinod
In 2.6.36 kernel, dma slave control command was introduced, this patch changes the intel-mid-dma driver to this new kernel slave interface Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2010-10-07intel_mid_dma: Add sg list support to DMA driverRamesh Babu K V
For a very high speed DMA various periphral devices need scatter-gather list support. The DMA hardware support link list items. This list can be circular also (adding new flag DMA_PREP_CIRCULAR_LIST) Right now this flag is in driver header and should be moved to dmaengine header file eventually Signed-off-by: Ramesh Babu K V <ramesh.b.k.v@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2010-10-07intel_mid_dma: Add runtime PM supportKoul, Vinod
This patch adds runtime PM support in this dma driver for 4 PCI Controllers Whenever the driver is idle (no channels grabbed), it can go to low power state It also adds the PCI suspend and resume support Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2010-07-27intel_mid: Add Mrst & Mfld DMA DriversVinod Koul
This patch add DMA drivers for DMA controllers in Langwell chipset of Intel(R) Moorestown platform and DMA controllers in Penwell of Intel(R) Medfield platfrom This patch adds support for Moorestown DMAC1 and DMAC2 controllers. It also add support for Medfiled GP DMA and DMAC1 controllers. These controllers supports memory to peripheral and peripheral to memory transfers. It support only single block transfers. This driver is based on Kernel DMA engine Anyone who wishes to use this controller should use DMA engine APIs This controller exposes DMA_SLAVE capabilities and notifies the client drivers of DMA transaction completion Config option required to be enabled CONFIG_INTEL_MID_DMAC=y Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
