[PATCH 01/10] dt/bindings: Add binding for BCM2835 mailbox driver

Eric Anholt

From: Lubomir Rintel <lkundrak-NGH9Lh4a5iE@public.gmane.org>

v2: Split into a separate patch for submitting to the devicetree list.
Consistently start node docs with a capital letter. device's
address in the example shouldn't have "0x". Drop machine-specific
interrupt numbers from the docs. (changes by anholt).
