2013-07-05dma: imx-sdma: move to generic device tree bindingsShawn Guo
Update imx-sdma driver to adopt generic DMA device tree bindings. It calls of_dma_controller_register() with imx-sdma specific of_dma_xlate to get the generic DMA device tree helper support. The #dma-cells for imx-sdma must be 3, which includes request ID, peripheral type and priority. The existing way of requesting channel, clients directly call dma_request_channel(), still work there, and will be removed after all imx-sdma clients get converted to generic DMA device tree helper.

2013-07-05dmaengine: sirf: set dma residue based on the current dma transfer positionRongjun Ying
read SIRFSOC_DMA_CH_ADDR register to get current dma transfer position, then update dma residue so that things like ALSA drivers work as ALSA drivers need the right residue value.

2013-07-05dma: tegra: avoid channel lock up after freeDmitry Osipenko
Lock scenario: Channel 1 was allocated and prepared as slave_sg, used and freed. Now preparation of cyclic dma on channel 1 will fail with err "DMA configuration conflict" because tdc->isr_handler still setted to handle_once_dma_done. This happens because tegra_dma_abort_all() won't be called on channel freeing if pending list is empty and channel not busy. We need to clear isr_handler on channel freeing to avoid locking.

2013-07-05dma: timb_dma: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound).

2013-07-05dma: use platform_{get,set}_drvdata()Jingoo Han
Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure.

2013-07-05DMA: AT91: Get residual bytes in dma bufferElen Song
Add support for returning the residue for current transfer cookie by reading the transfered buffer size(BTSIZE) in CTRLA register. For a single buffer cookie, the descriptor length minus BTSIZE can get the residue. For a lli cookie, remain_desc will record remain descriptor length when last descriptor finish, the remain_desc minus BTSIZE can get the current residue. If the cookie has completed successfully, the residue will be zero. If the cookie is in progress, it will be the number of bytes yet to be transferred. If get residue error, the cookie will be turn into error status. Check dma fifo to see if data remain, let issue pending finish remain work if there is.
