* 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.
|
|
|
|
Optional properties:
|
|
- toshiba,mmc-wrprotect-disable: write-protect detection is unavailable
|
|
|
|
When used with Renesas SDHI hardware, the following compatibility strings
|
|
configure various model-specific properties:
|
|
|
|
"renesas,sh7372-sdhi": (default) compatible with SH7372
|
|
"renesas,r8a7740-sdhi": compatible with R8A7740: certain MMC/SD commands have to
|
|
wait for the interface to become idle.
