[PATCH 0/5] sms911x: DTS fixes and DT binding to json-schema conversion

[Geert Uytterhoeven]

	Hi all,

This patch series converts the Smart Mixed-Signal Connectivity (SMSC)
LAN911x/912x Controller Device Tree binding documentation to
json-schema, after fixing a few issues in DTS files.

Thanks for your comments!

[PATCH 5/5] dt-bindings: net: sms911x: Convert to json-schema

[Geert Uytterhoeven]

Convert the Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x
Controller Device Tree binding documentation to json-schema.

Document missing properties.
Make "phy-mode" not required, as many DTS files do not have it, and the
Linux drivers falls back to PHY_INTERFACE_MODE_NA.
Correct nodename in example.

I have listed Shawn as the maintainer, as he wrote the original
bindings.  Shawn: Please scream if this is inappropriate ;-)

I left "additionalProperties: true", as there are lots of bus-specific
properties ("qcom,*", "samsung,*", "fsl,*", "gpmc,*", ...) to be found,
that actually depend on the compatible value of the parent node.

Can you put a comment above additionalProperties to that effect. I need 
to come up with some solution for this, but don't want folks copying 
that when normally not needed.
