  13 Changelog:
  14 V1 -> V5: generic settings is shared in bcm283x.dtsi, but disabled
  15           moved the compatible string to the SOC specific dtsi
  16             for arm and arm64
  17 V5 -> V6: fix remove 0x prefix from thermal@0x7e212000
  18
  19 Note: there is no arm/boot/dts/bcm2837.dtsi as of now,
  20       so the 32-bit rpi3 dt is not modified.
