Was this with v2024.02? It should be a bit better there. Though it 
may just have different errors. The limitation is that property 
types and in the case of matrix's (which phandle-array actually is) 
range for dimensions are global. So if there's not correct dimensions 
for a property, the tools aren't going to decode it properly.
