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