Sorry, I forgot to follow up on this.  I didn't understand Rob's comment,
because my patch only changed uppercase/lowercase.  I didn't add or remove
any '0x' or '0' prefixes.

From the context, I infer that we should have "v2m10: v2m@a0000" instead of
"v2m10: v2m@0xa0000".

I'll make a second patch that makes that change.  I do notice many other 
DTs that have similar constructs, e.g.,

  arch/arc/boot/dts/abilis_tb10x.dtsi:            spi0: spi@0xFE010000 {
  arch/arc/boot/dts/abilis_tb10x.dtsi:            spi1: spi@0xFE011000 {
  arch/arc/boot/dts/axc001.dtsi:          dw-apb-gpio@0x2000 {
  arch/arc/boot/dts/axc001.dtsi:          debug_uart: dw-apb-uart@0x5000 {
  ...

Maybe more opportunities for cleanup?
