We actually don't need to add these anymore, I fixed our topology
detection :) No harm to keep it though!

I figure this will be no surprise to you:
arch/riscv/boot/dts/thead/th1520-lichee-pi-4a.dtb: soc: cpurst: {'compatible': ['thead,reset-th1520'], 'entry-reg': [[1099494953040]], 'entry-cnt': [[4]], 'control-reg': [[255, 4278276100]], 'control-val': [[28]], 'csr-copy': [[2035, 1984, 1985, 1986, 1987, 1989, 1996]]} should not be valid under {'type': 'object'}
arch/riscv/boot/dts/thead/th1520-lichee-pi-4a.dtb: cpurst: control-reg:0: [255, 4278276100] is too long

^^^^^^^^^^^^^^^^^^^^^^^
These are spaces :(

I think you are trying to copy this from vendor's kernel?
would it be more proper/accurate to set as

~~~~~
probably you are writing this according to the address map?
from UART controller's perspective, it's valid reg range from 0x00 - 0xFF
so I think limiting the address space to 0x100 would be more proper?
less io space consumed, less page table needed?
