[PATCH 25/54] dt-bindings: mmc: Convert MMC Card binding to a schema

[PATCH 25/54] dt-bindings: mmc: Convert MMC Card binding to a schema

[Maxime Ripard]

MMC Cards can have an optional Device Tree binding to add
non-discoverable properties.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

Some of these properties were already described in the MMC controller
binding, even though they are not generic and do not apply to any
device, so we took the occasion to fix this.

Like what? If there's other properties, then there should really be a 
specific compatible.

I agree.

Maxime, thanks for working on this. I assume you will be sending a new
version that I can pick up?
