In k3 architecture a DMA channel (in TR momde) can be triggered by global events, origination from different modules. The events for triggers can be sent from any module which is connected to PSI-L fabric, but the event number to be sent is DMA channel specific, it is only known after the channel itself is requested. The router operation needs to be split up: - route_allocate: configure the dma_spec for the DMA and store the configuration which is needed for the router's input - set_event: callback used by the DMA driver to set the event number for the channel and enable the routing Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Link: https://lore.kernel.org/r/20201208090440.31792-16-peter.ujfalusi@ti.com Signed-off-by: Vinod Koul <vkoul@kernel.org> |
