[PATCH 2/3] dt-bindings: dma: rz-dmac: Document RZ/G3E family of SoCs

[PATCH 2/3] dt-bindings: dma: rz-dmac: Document RZ/G3E family of SoCs
Posted by Tommaso Merciai 2 months ago 
The DMAC block on the RZ/G3E SoC is identical to the one found on the
RZ/V2H(P) SoC.

No driver changes are required, as `renesas,r9a09g057-dmac` will be used
as a fallback compatible string on the RZ/G3E SoC.

Lore has the full series:
https://lore.kernel.org/all/20250801084825.471011-1-tommaso.merciai.xr@bp.renesas.com/

Only patch 2/3 was meant for you.
Patches 1/3 and 3/3 are clk and DTS patches, which I have already
applied to my renesas-clk and renesas-devel trees, as the new DT
binding is straightforward.

Thanks!
