* dmaengine: imx-sdma - correct the dma transfer residue calculationNandor Han2016-11-251-4/+9
| | | | | | | | | | | | | | | | | | | | | | The residue calculation was taking in consideration that dma transaction status will be always retrieved in the dma callback used to inform that dma transfer is complete. However this is not the case for all subsystems that use dma. Some subsystems use a timer to check the dma status periodically. Therefore the calculation was updated and residue is calculated accordingly by a) update the residue calculation taking in consideration the last used buffer index by using *buf_ptail* variable and b) chn_real_count (number of bytes transferred) is initialized to zero, when dma channel is created, to avoid using an uninitialized value in residue calculation when dma status is checked without waiting dma complete event.

* dmaengine: nbpfaxi: add optional max-burst property for memory reads/writesNiklas Cassel2016-11-141-4/+34
| | | | | | | | | | | | | | | | | | Due to a hardware bug, reading memory (from the Accelerator Coherency Port) with a burst size equal to the maximum burst size allowed by the DMA hardware's buffer size will cause a hardware hang on the ARTPEC-6 SoC, where the only solution is a manual power cycle. On ARTPEC-6, this hardware bug does not trigger when writing memory (to the Accelerator Coherency Port) with a burst size equal to the maximum burst size allowed by the DMA hardware's buffer size. To avoid this hardware hang, introduce a new optional max-burst property for memory reads. For completeness, also introduce a max-burst property for memory writes.

* dmaengine: tegra210-adma: convert TEGRA210_ADMA from bool to tristatePaul Gortmaker2016-11-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver currently uses modular infrastructure but is controlled by a bool Kconfig. There is a general consensus from the DMA reviewers and maintainers that "if it can be modular, it should be modular" in order to keep the bzImage size under control for multi platform kernels. Build tested only. Also needed some new pm_clk symbols exported before this commit is applied to tree in order to avoid modpost errors like: ERROR: "pm_clk_add_clk" [drivers/dma/tegra210-adma.ko] undefined!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Completion callback should happen after dma_descriptor_unmap() has happened. This allow the cache invalidate to happen and ensure that the data accessed by the upper layer is in memory that was from DMA rather than stale data. On some architecture this is done by the hardware, however we should make the code consistent to not cause confusion.
