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

Eric Anholt eric at anholt.net
Mon Mar 2 12:54:35 PST 2015


From: Lubomir Rintel <lkundrak at v3.sk>

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).
