* 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-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
