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.

28 - clocks: Most controllers only have 1 clock source per channel. However, on
29 some variations of this controller, the internal card detection
30 logic that exists in this controller is sectioned off to be run by a
31 separate second clock source to allow the main core clock to be turned
33 If 2 clocks are specified by the hardware, you must name them as
34 "core" and "cd". If the controller only has 1 clock, naming is not
36 Below is the number clocks for each supported SoC:
37 1: SH73A0, R8A73A4, R8A7740, R8A7778, R8A7779, R8A7790
38 R8A7791, R8A7792, R8A7793, R8A7794, R8A7795, R8A7796
42 - toshiba,mmc-wrprotect-disable: write-protect detection is unavailable
43 - pinctrl-names: should be "default", "state_uhs"
44 - pinctrl-0: should contain default/high speed pin ctrl
45 - pinctrl-1: should contain uhs mode pin ctrl
