From 3e7fc7d394db0783996519f2d5affde5152a628e Mon Sep 17 00:00:00 2001

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.
