Unfortunately not:

arch/arm64/boot/dts/renesas/r8a779f0-spider.dtb: thermal@e6198000:
reg: [[0, 3860430848, 0, 512], [0, 3860463616, 0, 512], [0,
3860496384, 0, 512]] is too short

As this controls both the presence of interrupts and the number of regs.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
