The device tree command line is located in the bootargs property of the

I think fdt_get_prop_offset() is a better name. The point of this
function is to return the offset in the fdt of the named property. "by"
or "as" confuses the purpose, at least to me.
Compare the existing fdt_get_property_by_offset() which is performing a
property looking by consulting the offset.
