1 | * Toshiba Mobile IO SD/MMC controller |
| 2 | ||
| 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. | |
