Dear All, this series adds SDHI2 support to the iwg23s. The RZ/G1C (the SoC powering the iwg23s) is slightly different from the other R-Car and RZ/G1 devices, in the sense that this device uses only one bit of the POC Control Register to control the voltage of the entire interface, as opposed to one bit per pin. There is a discussion on the ML that is going on about this: https://patchwork.kernel.org/patch/10604395/ and the patches from this series implement "option 2".
