'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

Devicetree-enabled boards should use proper regulators to control the

properties are supported by the MMC core and are described in the

Add fallback compatibility strings for R-Car Gen 1, 2 and 3.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.

This documents the devicetree bindings for the SDIO/MMC host found in

and the eMMC specification v4.41.
It has an internal "mux" which allows connecting up to three MMC devices
to it. The maximum supported bus-width is 4-bits.

Amlogic's GPL kernel sources call it "SDIO" to differentiate it from the
other MMC controller in (at least the Meson8 and Meson8b) the SoCs (they
call the other one "SDHC", which supports a bus-width of up to 8-bits).
