Ah, looks like femtofarads got added to property-units.txt but not the schemas. I'll add it, but fine to leave this as-is for now. Reviewed-by: Rob Herring <robh@kernel.org> Rob

There are two registers which can set the load capacitance for XTAL1 and XTAL2. These are optional registers when using an external crystal. Since XTAL1 and XTAL2 will set to the same value, update the binding to support a single property called xtal-load-femtofarads. Signed-off-by: Adam Ford <aford173@gmail.com> --- V3: No Change V2: No Change A couple people suggested that I not use the $ref, but without it, the bindings check failed with errors.
