Help. They are, but additionalProperties cannot 'see' into a $ref. You need to use 'unevaluatedProperties: false' instead. Note that 'unevaluatedProperties' is not supported by the underlying jsonschema package, so it doesn't yet have any effect. The other way to solve this is listing all the properties from the above schemas that can be used. I don't think that makes sense in this case. You should however, have 'clocks' here because otherwise 1-32 clock entries is valid. > Cc: devicetree@vger.kernel.org > Cc: Marek Vasut <marex@denx.de> > Signed-off-by: Linus Walleij <linus.walleij@linaro.org> > --- > .../devicetree/bindings/mmc/arm,pl18x.yaml | 208 ++++++++++++++++++ > .../devicetree/bindings/mmc/mmci.txt | 74 ------- > 2 files changed, 208 insertions(+), 74 deletions(-) > create mode 100644 Documentation/devicetree/bindings/mmc/arm,pl18x.yaml > delete mode 100644 Documentation/devicetree/bindings/mmc/mmci.txt > > diff --git a/Documentation/devicetree/bindings/mmc/arm,pl18x.yaml b/Documentation/devicetree/bindings/mmc/arm,pl18x.yaml > new file mode 100644 > index 000000000000..2e1157560d7a > --- /dev/null > +++ b/Documentation/devicetree/bindings/mmc/arm,pl18x.yaml > @@ -0,0 +1,208 @@ > +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/mmc/arm,pl18x.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: ARM PrimeCell MultiMedia Card Interface (MMCI) PL180 and PL181 > + > +maintainers: > + - Linus Walleij <linus.walleij@linaro.org> > + - Ulf Hansson <ulf.hansson@linaro.org> > + > +description: > + The ARM PrimeCells MMCI PL180 and PL181 provides an interface for > + reading and writing to MultiMedia and SD cards alike.
