hmm, I don't really understand this error message.

From a practical point, the dtschema-version I have installed is
2025.3.dev27+g32749b3, which is the topmost commit from
may-13th.

Running the dtbscheck on the rk3562-evb-v10.dtb on the full
linux-next from today, yields no errors.

Checking out the specific commit ceb6ef1ea90026 brings up the
errors from below [1], because they come from different trees.


But in no cases does dtbscheck complain about the PCI memory regions.


The PCIe controller in question of course has 3 memory regions
	reg = <0x0 0xfe000000 0x0 0x400000>,
	      <0x0 0xff500000 0x0 0x10000>,
	      <0x0 0xfc000000 0x0 0x100000>;
	reg-names = "dbi", "apb", "config";

and currently the node-name mimics the "apb" memory region.
Should it always use the first one?
