From: Pandith N <redacted> Added support for multiple DMA_MEM_TO_DEV, DMA_DEV_TO_MEM transfers in parallel. Peripherals can use DMA for both transmit and receive operations in parallel. To setup DMA handshaking, the peripheral source number to be programmed in respective channel select slot of AXIDMA_CTRL_DMA_HS_SEL. No need to check for free slot in dw_axi_dma_set_hw_channel(). The channel slot used in AXIDMA_CTRL_DMA_HS_SEL needs to be set in src_per/dst_per of CHx_CFG register Burst length, DMA HW capability set in dt-binding is now used in driver.
Applied, thanks -- ~Vinod
