   4 Subject: [PATCH] ARM: dts: sun7i: add WiFi module to Cubietruck DTS
   5
   6 The CubieTruck has an AMPAK AP6210 WiFi+Bluetooth module. The WiFi
   7 part is a BCM43362 IC connected to MMC2 in the A20 SoC via SDIO.
   8 The IC also takes a 32.768 KHz low power clock input, and a power
   9 enable signal via GPIO.
  10
  11 The WiFi module supports out-of-band interrupt signaling via GPIO,
  12 but this is not supported in this patch.
