   4 Subject: [PATCH 180/703] overlays: pi3-disable-bt: Clear out bt_pins node
   5
   6 The pi3-disable-bt overlay does not (and cannot) delete the bt_pins
   7 node, but emptying its properties (including brcm,pins) is a way of
   8 signalling to the hciuart systemd service that Bluetooth has been
   9 disabled.
