This gets us in sync with dts from kernel 4.11. Two patches were already backported earlier. I decided to use 03x prefix as it's kind of similar to the 3xx prefix: 3xx - architecture specific patches It isn't any documented or strict rule though. We don't need to stick to it if we hit any problems. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

Subject: [PATCH] ARM: bcm2835: dts: add thermal node to device-tree of bcm283x
 | 
						|
 | 
						|
Add the node for the thermal sensor of the bcm2835-soc
 | 
						|
to the device tree.

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.
