R8A77470) comes with three SDHI interfaces, SDHI0 and SDHI2 are compatible with R-Car Gen2 SDHIs, and SDHI1 is compatible with R-Car Gen3 SDHIs, as it comes with an internal DMAC, therefore SDHI1 is fully compatible with driver renesas_sdhi_internal_dmac driver. As a result, the compatible strings for the R8A77470 SDHI interfaces are a little bit special. Document SDHI support for the RZ/G1C SoC.
