In order to use this dmaengine with sound devices, let's add cyclic transfers support. Most of the code is reused from the existing scatter-gather implementation, only the final linking between descriptors, the control fields (to trigger interrupts more often) and the interrupt handling are really different. This controller supports up to 32 adjacent descriptors, we assume this is way more than enough for the purpose of cyclic transfers and limit to 32 the number of cycled descriptors. This way, we simplify a lot the overall handling of the descriptors. Signed-off-by:

In order to reduce and clarify the diff when introducing cyclic transfers support, let's first prepare the driver a bit. There is no functional change. Signed-off-by:

If probe is reached, we've already matched the device and in the case of DT matching, the struct device_node pointer will be set. Therefore, there is no need to call of_match_device() in probe. Signed-off-by:

Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers. Signed-off-by:

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). To do so, the code needs a little shuffling related to how hw_desc is used and nb_desc incremented. The one by one increment is needed for the error handling path, calling pxad_free_desc(), to work correctly. So, add a new intermediate variable, desc, to store the result of the dma_pool_alloc() call. Signed-off-by:

Christophe JAILLET authored
If pxad_alloc_desc() fails on the first dma_pool_alloc() call, then sw_desc->nb_desc is zero. In such a case pxad_free_desc() is called and it will BUG_ON(). Remove this erroneous BUG_ON(). It is also useless, because if "sw_desc->nb_desc == 0", then, on the first iteration of the for loop, i is -1 and the loop will not be executed. (both i and sw_desc->nb_desc are 'int') Fixes: a57e16cf ("dmaengine: pxa: add pxa dmaengine driver") Signed-off-by:

Since commit 7723f4c5 ("driver core: platform: Add an error message to platform_get_irq*()") and commit 2043727c ("driver core: platform: Make use of the helper function dev_err_probe()"), there is no need to call the dev_err() function directly to print a custom message when handling an error from platform_get_irq() function as it is going to display an appropriate error message in case of a failure.

With the possibility of multiple wq drivers that can be bound to the wq, the user config tool accel-config needs a way to know which wq driver to bind to the wq. Introduce per wq driver_name sysfs attribute where the user can indicate the driver to be bound to the wq. This allows accel-config to just bind to the driver using wq->driver_name. Signed-off-by:

Commit e39a2329 ("Kconfig: Allow k3dma driver to be selected for more then HISI3xx platforms") expanded the "depends on" line of K3_DMA from "ARCH_HI3xxx" to "ARCH_HI3xxx || ARCH_HISI || COMPILE_TEST". However, ARCH_HI3xxx implies ARCH_HISI, so it's unnecessary to list both. Instead, just list ARCH_HISI, which covers all HiSilicon platforms. Signed-off-by:
