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