Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The macros DMA_TX and DMA_RX in the global devicetree bindings header lack an SoC or vendor prefix, causing namespace pollution.

dt-bindings: dma: Add Amlogic A9 SoC DMA

This commit adds documentation describing the Amlogic A9 SoC DMA controller.
It also introduces a new include file containing specific property values
for DMA channels.

[Severity: Low]
Do these macro names need a vendor or SoC prefix like AMLOGIC_A9_DMA_TX?

Since they are in a global devicetree bindings header, using generic names
like DMA_TX and DMA_RX could pollute the global macro namespace. Are these
likely to collide with existing definitions in other driver headers and
cause macro redefinition build errors?
