[PATCH 3/3] dt-bindings: Fix errors in 'if' schemas

[PATCH 3/3] dt-bindings: Fix errors in 'if' schemas

[Rob Herring]

Properties in if/then schemas weren't getting checked by the meta-schemas.
Enabling meta-schema checks finds several errors.

The use of an 'items' schema (as opposed to the list form) is wrong in
some cases as it applies to all entries. 'contains' is the correct schema
to use in the case of multiple entries.

Single entry, so "contains" not needed?

Missing "contains"?

No, you are misunderstanding how these work. 'contains' means at least 
one entry in an array passes with the subschema. In this case, 
'renesas,usb2-phy-r7s9210' must appear somewhere in the 'compatible' 
values. (Before, it said *every* entry must be 
'renesas,usb2-phy-r7s9210'.) As there is a fallback compatible, we need 
'contains'.

No. In this case, 'compatible' is always a single entry, so no 
'contains' needed (but would work). If compatible is one of these 3 
strings, then the 'if' is true.

The original way would actually work in this case (i.e. is valid 
json-schema), but we require 'items' to have a size (maxItems/minItems) 
in our meta-schema.
