This is wrong and should have warned if you tested this on 5.3.

items:
  - const: sifive,fu540-c000-uart
  - const: sifive,uart0

Thanks for the correction, i will update this in v2 patch.

I haven't got any warnings due to my patch.
For your reference, following is the list of warnings when i did "make
dtbs_check" (kernel version - 5.3.0-rc7)
