   4 Subject: [PATCH] ARM: dts: sun7i: add bluetooth module to CubieTruck DTS
   5
   6 The CubieTruck has an AMPAK AP6210 WiFi+Bluetooth module. The
   7 Bluetooth part is a BCM20710 IC connected to UART2 in the A20
   8 SoC. The IC also takes a 32.768 KHz low power clock input, a power
   9 enable signal and a wake signal via GPIO.
  10
  11 The Bluetooth module supports out-of-band interrupt signaling via
  12 GPIO, but this is not supported in this patch.
