1 * Toshiba Mobile IO SD/MMC controller
3 The tmio-mmc driver doesn't probe its devices actively, instead its binding to
4 devices is managed by either MFD drivers or by the sh_mobile_sdhi platform
5 driver. Those drivers supply the tmio-mmc driver with platform data, that either
6 describe hardware capabilities, known to them, or are obtained by them from
7 their own platform data or from their DT information. In the latter case all
8 compulsory and any optional properties, common to all SD/MMC drivers, as
9 described in mmc.txt, can be used. Additionally the following tmio_mmc-specific
10 optional bindings can be used.
13 - compatible: should contain one or more of the following:
14 "renesas,sdhi-sh73a0" - SDHI IP on SH73A0 SoC

29 "renesas,sdhi-r8a77995" - SDHI IP on R8A77995 SoC
30 "renesas,sdhi-shmobile" - a generic sh-mobile SDHI controller
31 "renesas,rcar-gen1-sdhi" - a generic R-Car Gen1 SDHI controller
32 "renesas,rcar-gen2-sdhi" - a generic R-Car Gen2 or RZ/G1
34 "renesas,rcar-gen3-sdhi" - a generic R-Car Gen3 SDHI controller
37 When compatible with the generic version, nodes must list
38 the SoC-specific version corresponding to the platform
39 first followed by the generic version.
41 - clocks: Most controllers only have 1 clock source per channel. However, on
42 some variations of this controller, the internal card detection
43 logic that exists in this controller is sectioned off to be run by a
44 separate second clock source to allow the main core clock to be turned
46 If 2 clocks are specified by the hardware, you must name them as
47 "core" and "cd". If the controller only has 1 clock, naming is not
49 Devices which have more than 1 clock are listed below:
53 - pinctrl-names: should be "default", "state_uhs"
54 - pinctrl-0: should contain default/high speed pin ctrl
55 - pinctrl-1: should contain uhs mode pin ctrl
