* 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: "renesas,sdhi-shmobile" - a generic sh-mobile SDHI unit
"renesas,sdhi-sh7372" - SDHI IP on SH7372 SoC
"renesas,sdhi-sh73a0" - SDHI IP on SH73A0 SoC
"renesas,sdhi-r8a73a4" - SDHI IP on R8A73A4 SoC
"renesas,sdhi-r8a7740" - SDHI IP on R8A7740 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
Optional properties:
- toshiba,mmc-wrprotect-disable: write-protect detection is unavailable
- pinctrl-names: should be "default", "state_uhs"
- pinctrl-0: should contain default/high speed pin ctrl
- pinctrl-1: should contain uhs mode pin ctrl
