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

19 Note: there is no arm/boot/dts/bcm2837.dtsi as of now,
20       so the 32-bit rpi3 dt is not modified.
