As commit b6147490e6aa ("mmc: tmio: split core functionality, DMA and
MFD glue") said, these MMC controllers use the IP from Panasonic.
TMIO (Toshiba Mobile IO) MMC was the first upstreamed user of this IP.
The common driver code was split and expanded as 'tmio-mmc-core', then
it become historical misnomer since 'tmio' is not the name of this IP
in the first place.
In the discussion [1], we decide to keep calling these MMC variants
'TMIO MMC' at least in Linux driver level because renaming all of them
is a big churn.
However, DT should not be oriented to a particular project even though
it is developed in Linux communities.
Let's stop exporting this unfortunate things to other projects, where
there is no good reason to call this "TMIO". Rename the file to
renesas_sdhi.txt. In fact, all the information in this file is specific
to the Renesas platform.
This commit also removes the first paragraph entirely. The DT-binding
should describe the hardware. It is really strange to talk about Linux
driver internals such as how the drivers are probed, how platform data
are handed off, etc.

-* 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.
