The "qcom,paired" schema is all wrong. First, it's a list rather than an
object(dictionary). Second, it is missing a required type. The meta-schema
normally catches this, but schemas under "$defs" was not getting checked.
A fix for that is pending.

Current Linux implementation uses it as a generic pinconf param
pinconf_generic_params which is parsed by:
pinconf_generic_parse_dt_config() -> parse_dt_cfg() ->
of_property_read_u32()
The pinctrl-spmi-mpp.c driver, using this schema, treat it as a bool,
but I still wonder how the code will parse bool with
of_property_read_u32(). Maybe it should be uint32 with value of 0 and 1?
Best regards,
Krzysztof

That should be an error because the length is too short so it should
go with some default from the code.
Looks like there is no user, though no property could mean keep the
default/bootloader setting. Can you sort out which type is really
desired here and hopefully we can get rid of the other type. It's not
the first case of pinctrl properties with multiple types, but we don't
really need more.

Still an issue here. Please sort out what functionality QCom wants here.
dtschema (main br) will now throw a warning on it.

I think we can go with your patch, after double checking my previous
concerns are not relevant here - driver reads it as bool just like other
bool properties.

Linus,
Could you take it for current fixes? The code was wrong and dtschema is
warning now about this.

I have other things ready for 6.4, so I'll add this one.
