[Martin Blumenstingl <martin.blumenstingl@googlemail.com>]

Hi Mohammad,

this patch should be third in the series.
the currently missing patch for the dt-bindings should be patch two.
you can take the following commit as an example:
effdd8a6b6ecb30b088f36ed0a1fb67cdc7610a9 ("dt-bindings: arm: amlogic:
add SEI Robotics SEI610 bindings")

this property seems to be deprecated now, see
Documentation/devicetree/bindings/leds/common.txt
but I'm not sure whether Kevin has made a decision yet when to not
accept "label" properties here anymore

please name this button-reset (even though we've done it wrong for
other boards in the past)
@0 indicates a unit-address, but the button has no address

thank you for switching to the new PHY bindings :)

assuming Kevin still accepts the LED "label" and you rename the button
node then you can add my:

(don't forget that we still need an additional dt-bindings patch though)
