SDHI1 IP on the other hand is compatible with R-Car Gen3 with internal DMA. This patch completes the SDHI support of the R-Car Gen2 compatible IPs, including fixing the max-frequency definition of SDHI2, as it turns out there is a bug in Section 1.3.9 of the RZ/G1C Hardware User's Manual (Rev. 1.00 Oct. 2017).
