* Toshiba Mobile IO SD/MMC controller The tmio-mmc driver doesn't probe its devices actively, instead its binding to devices is managed by either MFD drivers or by the sh_mobile_sdhi platform driver. Those drivers supply the tmio-mmc driver with platform data, that either describe hardware capabilities, known to them, or are obtained by them from their own platform data or from their DT information. In the latter case all compulsory and any optional properties, common to all SD/MMC drivers, as described in mmc.txt, can be used. Additionally the following tmio_mmc-specific optional bindings can be used. Required properties: - compatible: should contain one or more of the following: "renesas,sdhi-sh73a0" - SDHI IP on SH73A0 SoC "renesas,sdhi-r7s72100" - SDHI IP on R7S72100 SoC "renesas,sdhi-r7s9210" - SDHI IP on R7S9210 SoC "renesas,sdhi-r8a73a4" - SDHI IP on R8A73A4 SoC "renesas,sdhi-r8a7740" - SDHI IP on R8A7740 SoC "renesas,sdhi-r8a7743" - SDHI IP on R8A7743 SoC "renesas,sdhi-r8a7744" - SDHI IP on R8A7744 SoC "renesas,sdhi-r8a7745" - SDHI IP on R8A7745 SoC "renesas,sdhi-r8a774a1" - SDHI IP on R8A774A1 SoC "renesas,sdhi-r8a774c0" - SDHI IP on R8A774C0 SoC "renesas,sdhi-r8a77470" - SDHI IP on R8A77470 SoC "renesas,sdhi-mmc-r8a77470" - SDHI/MMC IP on R8A77470 SoC "renesas,sdhi-r8a7778" - SDHI IP on R8A7778 SoC "renesas,sdhi-r8a7779" - SDHI IP on R8A7779 SoC "renesas,sdhi-r8a7790" - SDHI IP on R8A7790 SoC "renesas,sdhi-r8a7791" - SDHI IP on R8A7791 SoC "renesas,sdhi-r8a7792" - SDHI IP on R8A7792 SoC "renesas,sdhi-r8a7793" - SDHI IP on R8A7793 SoC "renesas,sdhi-r8a7794" - SDHI IP on R8A7794 SoC "renesas,sdhi-r8a7795" - SDHI IP on R8A7795 SoC "renesas,sdhi-r8a7796" - SDHI IP on R8A7796 SoC "renesas,sdhi-r8a77965" - SDHI IP on R8A77965 SoC "renesas,sdhi-r8a77970" - SDHI IP on R8A77970 SoC "renesas,sdhi-r8a77980" - SDHI IP on R8A77980 SoC "renesas,sdhi-r8a77990" - SDHI IP on R8A77990 SoC "renesas,sdhi-r8a77995" - SDHI IP on R8A77995 SoC "renesas,sdhi-shmobile" - a generic sh-mobile SDHI controller "renesas,rcar-gen1-sdhi" - a generic R-Car Gen1 SDHI controller "renesas,rcar-gen2-sdhi" - a generic R-Car Gen2 and RZ/G1 SDHI (not SDHI/MMC) controller "renesas,rcar-gen3-sdhi" - a generic R-Car Gen3 or RZ/G2 SDHI controller When compatible with the generic version, nodes must list the SoC-specific version corresponding to the platform first followed by the generic version. - clocks: Most controllers only have 1 clock source per channel. However, on some variations of this controller, the internal card detection logic that exists in this controller is sectioned off to be run by a separate second clock source to allow the main core clock to be turned off to save power. If 2 clocks are specified by the hardware, you must name them as "core" and "cd". If the controller only has 1 clock, naming is not required. Devices which have more than 1 clock are listed below: 2: R7S72100, R7S9210 Optional properties: - pinctrl-names: should be "default", "state_uhs" - pinctrl-0: should contain default/high speed pin ctrl - pinctrl-1: should contain uhs mode pin ctrl Example: R8A7790 (R-Car H2) SDHI controller nodes sdhi0: sd@ee100000 { compatible = "renesas,sdhi-r8a7790", "renesas,rcar-gen2-sdhi"; reg = <0 0xee100000 0 0x328>; interrupts = ; clocks = <&cpg CPG_MOD 314>; dmas = <&dmac0 0xcd>, <&dmac0 0xce>, <&dmac1 0xcd>, <&dmac1 0xce>; dma-names = "tx", "rx", "tx", "rx"; max-frequency = <195000000>; power-domains = <&sysc R8A7790_PD_ALWAYS_ON>; resets = <&cpg 314>; }; sdhi1: sd@ee120000 { compatible = "renesas,sdhi-r8a7790", "renesas,rcar-gen2-sdhi"; reg = <0 0xee120000 0 0x328>; interrupts = ; clocks = <&cpg CPG_MOD 313>; dmas = <&dmac0 0xc9>, <&dmac0 0xca>, <&dmac1 0xc9>, <&dmac1 0xca>; dma-names = "tx", "rx", "tx", "rx"; max-frequency = <195000000>; power-domains = <&sysc R8A7790_PD_ALWAYS_ON>; resets = <&cpg 313>; }; sdhi2: sd@ee140000 { compatible = "renesas,sdhi-r8a7790", "renesas,rcar-gen2-sdhi"; reg = <0 0xee140000 0 0x100>; interrupts = ; clocks = <&cpg CPG_MOD 312>; dmas = <&dmac0 0xc1>, <&dmac0 0xc2>, <&dmac1 0xc1>, <&dmac1 0xc2>; dma-names = "tx", "rx", "tx", "rx"; max-frequency = <97500000>; power-domains = <&sysc R8A7790_PD_ALWAYS_ON>; resets = <&cpg 312>; }; sdhi3: sd@ee160000 { compatible = "renesas,sdhi-r8a7790", "renesas,rcar-gen2-sdhi"; reg = <0 0xee160000 0 0x100>; interrupts = ; clocks = <&cpg CPG_MOD 311>; dmas = <&dmac0 0xd3>, <&dmac0 0xd4>, <&dmac1 0xd3>, <&dmac1 0xd4>; dma-names = "tx", "rx", "tx", "rx"; max-frequency = <97500000>; power-domains = <&sysc R8A7790_PD_ALWAYS_ON>; resets = <&cpg 311>; };
