Subject: [PATCH 0/3] Remove shdma DT support
Date: Fri, 11 Jun 2021 12:18:38 +0200	[thread overview]
Message-ID: <cover.1623405675.git.geert+renesas@glider.be> (raw)

	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!
