PM / Runtime: Rework the "runtime idle" helper routine The "runtime idle" helper routine, rpm_idle(), currently ignores return values from .runtime_idle() callbacks executed by it. However, it turns out that many subsystems use pm_generic_runtime_idle() which checks the return value of the driver's callback and executes pm_runtime_suspend() for the device unless that value is not 0. If that logic is moved to rpm_idle() instead, pm_generic_runtime_idle() can be dropped and its users will not need any .runtime_idle() callbacks any more. Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle() routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and ata_port_runtime_idle(), respectively, as well as a few drivers' ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has been returned by the .runtime_idle() callback executed by it. To reduce overall code bloat, make the changes described above. Tested-by: Mika Westerberg <mika.westerberg@linux.intel.com> Tested-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Rafael J.

Drivers: dma: remove __dev* attributes. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

dmaengine: Use dma_sg_len(sg) instead of sg->length sg->length may or may not contain the length of the dma region to transfer, depending on the architecture - dma_sg_len(sg) always will though. For the architectures which use the drivers modified by this patch it probably is the case that sg->length contains the dma transfer length. But to be consistent and future proof change them to use dma_sg_len. To quote Russel King: sg->length is meaningless to something performing DMA. In cases where sg_dma_len(sg) and sg->length are the same storage, then there's no problem. But scatterlists _can_ (and one some architectures) do split them - especially when you have an IOMMU which can allow you to combine a scatterlist into fewer entries. So, anything using sg->length for the size of a scatterlist's DMA transfer _after_ a call to dma_map_sg() is almost certainly buggy. The patch has been generated using the following coccinelle patch: <smpl> @@ struct scatterlist *sg; expression X; @@ -sg[X].length +sg_dma_len(&sg[X]) @@ struct scatterlist *sg; @@ -sg->length +sg_dma_len(sg) </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>

dmaengine: Use sg_dma_address instead of sg_phys dmaengine drivers should always use sg_dma_address instead of sg_phys to get the addresses for the transfer from a sg element. To quote Russel King: sg_phys(sg) of course has nothing to do with DMA addresses. It's the physical address _to the CPU_ of the memory associated with the scatterlist entry. That may, or may not have the same value for the DMA engine, particularly if IOMMUs are involved. And if these drivers are used on ARM, they must be fixed, sooner rather than later. There's patches in the works which will mean we will end up with IOMMU support in the DMA mapping later, which means everything I've said above will become reality.

intel_mid_dma: Add runtime PM support 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>

intel_mid: Add Mrst & Mfld DMA Drivers 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>
