dt-bindings: dmaengine: zynqmp_dma: Add a new compatible string

2024-08-29T17:16:16Z

Add compatible string "amd,versal2-dma-1.0" to support AMD Versal Gen 2 platform. AMD Versal Gen 2 has 8 LPD DMA IPs in PS that can be used as general purpose DMAs which is designed to support memory to memory and memory to IO buffer transfer. Versal Gen 2 DMA IP has different interrupt register offset.

dt-bindings: dmaengine: zynqmp_dma: add xlnx,bus-width required property

2023-09-28T11:22:40Z

xlnx,bus-width is a required property. In yaml conversion somehow it got missed out. Bring it back and mention it in required list. Also add Harini and myself to the maintainer list.

dt-bindings: dmaengine: xilinx_dma: Add xlnx,irq-delay property

2023-08-21T13:10:36Z

Add an optional AXI DMA property 'xlnx,irq-delay'. It specifies interrupt timeout value and causes the DMA engine to generate an interrupt after the delay time period has expired. Timer begins counting at the end of a packet and resets with receipt of a new packet or a timeout event occurs. This property is useful when AXI DMA is connected to the streaming IP i.e axiethernet where inter packet latency is critical while still taking the benefit of interrupt coalescing.

dt-bindings: dmaengine: xilinx_dma:Add xlnx,axistream-connected property

2023-08-21T13:10:36Z

Add an optional AXI DMA property 'xlnx,axistream-connected'. This can be specified to indicate that DMA is connected to a streaming IP in the hardware design and dma driver needs to do some additional handling i.e pass metadata and perform streaming IP specific configuration.

dt-bindings: drop redundant part of title (end)

dt-bindings: dmaengine: xilinx_dma: Add MCMDA channel ID index description

2022-04-20T10:14:37Z

MCDMA IP provides up to 16 multiple channels of data movement each on MM2S and S2MM paths. Inline with implementation, in the binding add description for the channel ID start index and mention that it's fixed irrespective of the MCDMA IP configuration(number of read/write channels).
