The compatibles "ti,omap-sdma" and "ti,dra7-dma-crossbar" aren't documented
by a schema which causes warnings:

As no one has cared to fix them, just drop them.

flow cfg register regions which are usually configured by a Device
Management firmware. But certain entities such as bootloader (like
U-Boot) may have to access them directly. Describe this region in the

Keep the binding compatible with existing DTS files by requiring first

...
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.

Add new compatible for BAM DMA engine version v1.7.4 which is
found on Qualcomm SM6115 and QCM2290 SoCs. Since its very similar
to v1.7.0 used on SM8150 like SoCs, mark the comptible scheme
accordingly.
While at it, also update qcom,bam-dma bindings to add comments
which describe the BAM DMA versions used in SM8150 and SM8250 SoCs.
This provides an easy reference for identifying the actual BAM DMA
version available on Qualcomm SoCs.

Extend the DMA40 bindings so that we can pass two SRAM
segments as phandles instead of directly referring to the
memory address in the second reg cell. This enables more
granular control over the SRAM, and adds the optiona LCLA
SRAM segment as well.
Deprecate the old way of passing LCPA as a second reg cell,
make sram compulsory.

Drop "interrupt-names" property, since it is broken. The drivers/dma/mxs-dma.c
in Linux kernel does not use it, the property contains duplicate array entries
in existing DTs, and even malformed entries (gmpi, should have been gpmi). Get
