On SM8550, the GPI DMA controller is coherent with the CPU.
Allow specifying that.

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

2023-09-28T11:22:40+00:00

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.

Extend Freescale eDMA driver bindings to support eDMA3 IP blocks in
i.MX8QM and i.MX8QXP SoCs. In i.MX93, both eDMA3 and eDMA4 are now.

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

2023-08-21T13:10:36+00:00

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

2023-08-21T13:10:36+00:00

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: dma: qcom,bam: require one of control methods

2023-07-12T16:54:01+00:00

The BAM DMA resources can be controlled remotely (e.g. by trusted
environment; needs qcom,powered-remotely or qcom,controlled-remotely
properties) or locally.  In the latter case we need to provide its
clock.

Require one of methods of such control to properly validate DTS.
