1* Toshiba Mobile IO SD/MMC controller 2 3The tmio-mmc driver doesn't probe its devices actively, instead its binding to 4devices is managed by either MFD drivers or by the sh_mobile_sdhi platform 5driver. Those drivers supply the tmio-mmc driver with platform data, that either 6describe hardware capabilities, known to them, or are obtained by them from 7their own platform data or from their DT information. In the latter case all 8compulsory and any optional properties, common to all SD/MMC drivers, as 9described in mmc.txt, can be used. Additionally the following tmio_mmc-specific 10optional bindings can be used. 11 12Required properties: 13- compatible: should contain one or more of the following: 14 "renesas,sdhi-sh73a0" - SDHI IP on SH73A0 SoC 15 "renesas,sdhi-r7s72100" - SDHI IP on R7S72100 SoC 16 "renesas,sdhi-r8a73a4" - SDHI IP on R8A73A4 SoC 17 "renesas,sdhi-r8a7740" - SDHI IP on R8A7740 SoC 18 "renesas,sdhi-r8a7743" - SDHI IP on R8A7743 SoC 19 "renesas,sdhi-r8a7745" - SDHI IP on R8A7745 SoC 20 "renesas,sdhi-r8a7778" - SDHI IP on R8A7778 SoC 21 "renesas,sdhi-r8a7779" - SDHI IP on R8A7779 SoC 22 "renesas,sdhi-r8a7790" - SDHI IP on R8A7790 SoC 23 "renesas,sdhi-r8a7791" - SDHI IP on R8A7791 SoC 24 "renesas,sdhi-r8a7792" - SDHI IP on R8A7792 SoC 25 "renesas,sdhi-r8a7793" - SDHI IP on R8A7793 SoC 26 "renesas,sdhi-r8a7794" - SDHI IP on R8A7794 SoC 27 "renesas,sdhi-r8a7795" - SDHI IP on R8A7795 SoC 28 "renesas,sdhi-r8a7796" - SDHI IP on R8A7796 SoC 29 "renesas,sdhi-r8a77965" - SDHI IP on R8A77965 SoC 30 "renesas,sdhi-r8a77980" - SDHI IP on R8A77980 SoC 31 "renesas,sdhi-r8a77990" - SDHI IP on R8A77990 SoC 32 "renesas,sdhi-r8a77995" - SDHI IP on R8A77995 SoC 33 "renesas,sdhi-shmobile" - a generic sh-mobile SDHI controller 34 "renesas,rcar-gen1-sdhi" - a generic R-Car Gen1 SDHI controller 35 "renesas,rcar-gen2-sdhi" - a generic R-Car Gen2 or RZ/G1 36 SDHI controller 37 "renesas,rcar-gen3-sdhi" - a generic R-Car Gen3 SDHI controller 38 39 40 When compatible with the generic version, nodes must list 41 the SoC-specific version corresponding to the platform 42 first followed by the generic version. 43 44- clocks: Most controllers only have 1 clock source per channel. However, on 45 some variations of this controller, the internal card detection 46 logic that exists in this controller is sectioned off to be run by a 47 separate second clock source to allow the main core clock to be turned 48 off to save power. 49 If 2 clocks are specified by the hardware, you must name them as 50 "core" and "cd". If the controller only has 1 clock, naming is not 51 required. 52 Devices which have more than 1 clock are listed below: 53 2: R7S72100 54 55Optional properties: 56- pinctrl-names: should be "default", "state_uhs" 57- pinctrl-0: should contain default/high speed pin ctrl 58- pinctrl-1: should contain uhs mode pin ctrl 59 60Example: R8A7790 (R-Car H2) SDHI controller nodes 61 62 sdhi0: sd@ee100000 { 63 compatible = "renesas,sdhi-r8a7790", "renesas,rcar-gen2-sdhi"; 64 reg = <0 0xee100000 0 0x328>; 65 interrupts = <GIC_SPI 165 IRQ_TYPE_LEVEL_HIGH>; 66 clocks = <&cpg CPG_MOD 314>; 67 dmas = <&dmac0 0xcd>, <&dmac0 0xce>, 68 <&dmac1 0xcd>, <&dmac1 0xce>; 69 dma-names = "tx", "rx", "tx", "rx"; 70 max-frequency = <195000000>; 71 power-domains = <&sysc R8A7790_PD_ALWAYS_ON>; 72 resets = <&cpg 314>; 73 }; 74 75 sdhi1: sd@ee120000 { 76 compatible = "renesas,sdhi-r8a7790", "renesas,rcar-gen2-sdhi"; 77 reg = <0 0xee120000 0 0x328>; 78 interrupts = <GIC_SPI 166 IRQ_TYPE_LEVEL_HIGH>; 79 clocks = <&cpg CPG_MOD 313>; 80 dmas = <&dmac0 0xc9>, <&dmac0 0xca>, 81 <&dmac1 0xc9>, <&dmac1 0xca>; 82 dma-names = "tx", "rx", "tx", "rx"; 83 max-frequency = <195000000>; 84 power-domains = <&sysc R8A7790_PD_ALWAYS_ON>; 85 resets = <&cpg 313>; 86 }; 87 88 sdhi2: sd@ee140000 { 89 compatible = "renesas,sdhi-r8a7790", "renesas,rcar-gen2-sdhi"; 90 reg = <0 0xee140000 0 0x100>; 91 interrupts = <GIC_SPI 167 IRQ_TYPE_LEVEL_HIGH>; 92 clocks = <&cpg CPG_MOD 312>; 93 dmas = <&dmac0 0xc1>, <&dmac0 0xc2>, 94 <&dmac1 0xc1>, <&dmac1 0xc2>; 95 dma-names = "tx", "rx", "tx", "rx"; 96 max-frequency = <97500000>; 97 power-domains = <&sysc R8A7790_PD_ALWAYS_ON>; 98 resets = <&cpg 312>; 99 }; 100 101 sdhi3: sd@ee160000 { 102 compatible = "renesas,sdhi-r8a7790", "renesas,rcar-gen2-sdhi"; 103 reg = <0 0xee160000 0 0x100>; 104 interrupts = <GIC_SPI 168 IRQ_TYPE_LEVEL_HIGH>; 105 clocks = <&cpg CPG_MOD 311>; 106 dmas = <&dmac0 0xd3>, <&dmac0 0xd4>, 107 <&dmac1 0xd3>, <&dmac1 0xd4>; 108 dma-names = "tx", "rx", "tx", "rx"; 109 max-frequency = <97500000>; 110 power-domains = <&sysc R8A7790_PD_ALWAYS_ON>; 111 resets = <&cpg 311>; 112 }; 113
