2013-11-13Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

2013-11-13dma: mxs-dma: Use semaphores for cyclic DMAMarkus Pargmann
mxs dma channel hardware reset command is not reliable and can cause a channel stall. The only way to fix the channel stall is a DMA engine reset. To avoid channel resets we use the hardware semaphore counter. For each transmitted segment, the DMA channel will decrease the counter by one. To use this mechanism with cyclic DMA, we need to increase the semaphore counter with each completed DMA command in the interrupt handler. To avoid any interruptions between the DMA transfers, the semaphore counter is initialized with 2. This way the counter can be increased in the interrupt handler without an influence on the transfer of the DMA engine. When disabling the channel, we stop increasing the semaphore counter in the interrupt handler. This patch was tested on i.MX28 with the SAIF DMA channel.

2013-11-13dma: mxs-dma: Fix channel reset hardware bugMarkus Pargmann
This is no official errata, but I noticed that the channel reset may stop working if the DMA state engine is in the READ_FLUSH state. This patch uses the channel debug1 register to wait for the DMA statemachine to leave the READ_FLUSH state. After that we can continue to reset the channel. Tested on i.MX28.

2013-11-13dma: mxs-dma: Cleanup interrupt handlerMarkus Pargmann

2013-11-12dma: cppi41: redo descriptor collection in abort caseSebastian Andrzej Siewior
Most of the logic here is try and error since what actually happens does not match the trm or I miss read it. My first assumption was that the queue on which the tear-down descriptor completes (their own complete queue vs "active descriptor" complete queue) depends on the transfer direction. This seems not to be true because I manage to trigger | WARN_ON(c->desc_phys != desc_phys); and the other few were fine means the tear-down descriptor was valid but on different queue.

2013-11-12dma: edma: Add support for Cyclic DMAJoel Fernandes
Using the PaRAM configuration function that we split for reuse by the different DMA types, we implement Cyclic DMA support. For the cyclic case, we pass different configuration parameters to this function, and handle all the Cyclic-specific functionality separately. Callbacks to the DMA users are handled using vchan_cyclic_callback in the virt-dma layer. Linking is handled the same way as the slave SG case except for the last slot where we link it back to the first one in a cyclic fashion. For continuity, we check for cases where no.of periods is great than the MAX number of slots the driver can allocate for a particular descriptor and error out on such cases.

2013-10-31ARM: 7857/1: dma: imx-sdma: setup dma maskPhilippe Retornaz
The dma mask is not configured in the current code. This was triggered by soc-dmaengine-pcm which allocate the dma buffers with the imx-sdma as device. This commit fix audio on imx31.

2013-10-31DMA-API: dma: edma.c: no need to explicitly initialize DMA masksRussell King
register_platform_device_full() can setup the DMA mask provided the appropriate member is set in struct platform_device_info. So lets make that be the case. This avoids a direct reference to the DMA masks by this driver. While here, add the dma_set_mask_and_coherent() call which the DMA API requires DMA-using drivers to call. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2013-10-31DMA-API: dma: dw_dmac.c: convert to use dma_coerce_mask_and_coherent()Russell King
This code sequence: if (!pdev->dev.dma_mask) { pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask; pdev->dev.coherent_dma_mask = DMA_BIT_MASK(32); } bypasses the architectures check on the DMA mask. It can be replaced with dma_coerce_mask_and_coherent(), avoiding the direct initialization of this mask. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2013-10-31DMA-API: dma: pl330: add dma_set_mask_and_coherent() callRussell King
The DMA API requires drivers to call the appropriate dma_set_mask() functions before doing any DMA mapping. Add this required call to the AMBA PL330 driver. Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2013-10-31dma: pl330: Remove unnecessary amba_set_drvdata()Michal Simek
Driver core clears the driver data to NULL after device_release or on probe failure, so just remove it from here.

So, fix these by converting them to %llx and casting the dma_addr_t to always be unsigned long long. While we're here, also use %zu for size_t.
