2022-07-26dmaengine: sprd: Cleanup in .remove() after pm_runtime_get_sync() failedUwe Kleine-König1-4/+1
It's not allowed to quit remove early without cleaning up completely. Otherwise this results in resource leaks that probably yield graver problems later. Here for example some tasklets might survive the lifetime of the sprd-dma device and access sdev which is freed after .remove() returns. As none of the device freeing requires an active device, just ignore the return value of pm_runtime_get_sync().

2022-07-26dmaengine: tegra: Add terminate() for Tegra234Akhil R1-2/+24
In certain cases where the DMA client bus gets corrupted or if the end device ceases to send/receive data, DMA can wait indefinitely for the data to be received/sent. Attempting to terminate the transfer will put the DMA in pause flush mode and it remains there. The channel is irrecoverable once this pause times out in Tegra194 and earlier chips. Whereas, from Tegra234, it can be recovered by disabling the channel and reprograming it. Hence add a new terminate() function that ignores the outcome of dma_pause() so that terminate_all() can proceed to disable the channel.

2022-07-21dmaengine: imx-sdma: Add FIFO stride support for multi FIFO scriptShengjiu Wang2-2/+38
The peripheral may have several FIFOs, but some case just select some FIFOs from them for data transfer, which means FIFO0 and FIFO2 may be selected. So add FIFO address stride support, 0 means all FIFOs are continuous, 1 means 1 word stride between FIFOs. All stride between FIFOs should be same. Another option words_per_fifo means how many audio channel data copied to one FIFO one time, 1 means one channel per FIFO, 2 means 2 channels per FIFO. If 'n_fifos_src = 4' and 'words_per_fifo = 2', it means the first two words(channels) fetch from FIFO0 and then jump to FIFO1 for next two words, and so on after the last FIFO3 fetched, roll back to FIFO0.

Each thread rewrite channels's descriptor as soon as device_prep_dma_memcpy() is called. It leads to the situation when the driver thinks that it uses right descriptor that actually is freed or substituted for other one. With current fixes a descriptor changes its value only when it has been used. A new descriptor is acquired from vc->desc_issued queue that is already filled with descriptors that are ready to be sent. Threads have no direct access to DMA channel descriptor. Now it is just possible to queue a descriptor for further processing.

2022-07-05dmaengine: sun4i: Set the maximum segment sizeSamuel Holland1-5/+27
The sun4i DMA engine supports transfer sizes up to 128k for normal DMA and 16M for dedicated DMA, as documented in the A10 and A20 manuals. Since this is larger than the default segment size limit (64k), exposing the real limit reduces the number of transfers needed for a transaction. However, because the device can only report one segment size limit, we have to expose the smaller limit from normal DMA. One complication is that the driver combines pairs of periodic transfers to reduce programming overhead. This only works when the period size is at most half of the maximum transfer size. With the default 64k segment size limit, this was always the case, but for normal DMA it is no longer guaranteed. Skip the optimization if the period is too long; even without it, the overhead is less than before.
