As before, CC at least the DT binding to the DT binding maintainers. > diff --git a/Documentation/devicetree/bindings/thermal/raspberrypi,bcm2835-thermal.txt b/Documentation/devicetree/bindings/thermal/raspberrypi,bcm2835-thermal.txt > +Raspberry Pi Broadcom BCM2835 thermal control > + > +Required properties: This needs some more explanation of what this is intended to represent and do. For example, what services is this node (the driver instantiated by this node) expected to implement, and what firmware services is it expected to rely upon?
