An updated version of an shdma driver platform driver conversion and Device Tree support. No functional changes since v2/v3, just made some structs const, updated documentation, removed an unused generic DT match entry, adjusted file order in the Makefile.
Patch 9 "DMA: shdma: support referencing specific DMACs within a multiplexer in DT" is actually an RFC. It proposes a method to support referencing a specific DMAC ninstance within a multiplexer DT node from slave DT nodes. As described in the documentation, the idea is to add a "#dma-cells" property to DMAC instances, that has to be made available for such targeted channel allocation. AFAICS, this is the only way to support both muxed and targeted referencing without core code modifications.
