* dmaengine: Add helper function to prep for error reportingDave Jiang2016-08-081-0/+72
| | | | | | | | | | | | | | Dmaengine does not provide a way to pass back the result from a DMA transaction through the callback function. We are adding dmaengine helper function in order to prep for a mechanism that allow result status and other information through the callback. The initial conversion will make the existing driver use these new helper functions but retain the original behavior of the code. However, the helper functions paves a way towards adding the result parameter through callback.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the function which wait until a dma channel is stopped to have a synchronization point. This also protects the pxad_remove() from races, such as spurious interrupts while removing the driver, because : - as long as there is one dma channel requested, ie. dma_chan_get() but no dma_chan_put(), the try_module_get() of dma_chan_get() prevents the remove() routine from running - when the last channel is released, ie. the last dma_chan_put() is called, if there is a running DMA, pxad_synchronize() is called - pxad_synchronize() waits for the channel to stop, which in turn ensures on pxa architecture that the interrupt cannot be fired anymore Reported-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
