These bindings were originally intended to cover all SH/R-Mobile SoCs, but the DMA multiplexer node and one DMA controller instance were only ever added to one .dtsi file, for R-Mobile APE6. Still, DMA support for R-Mobile APE6 was never completed to the point that it would actually work, cfr. commit a19788612f51b787 ("dmaengine: sh: Remove R-Mobile APE6 support"). Later, the mux idea was dropped when implementing support for DMA on (very similar) R-Car Gen2, cfr. renesas,rcar-dmac.yaml. Hence this series removes the Renesas SHDMA Device Tree bindings, the SHDMA DMA multiplexer driver, and the corresponding description in the R-Mobile APE6 DTS. I plan to queue [PATCH 3/3] in renesas-devel for v5.15. Thanks for your comments!
