Hi all,
Documentation/devicetree/bindings/dma/renesas,shdma.txt is one of the
few^W57% of the DT bindings that haven't been converted to json-schema
yet. 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!
