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.
