From: Akhil Goyal <akhil.goyal@freescale.com>
For platforms like BSC9131 and BSC9132, a Radio framework for supporting various network modes comprise of an Antenna interface controller driver and a phy driver. A combination of AIC lane and phy is called a rf device which can be used to operate on a particular network mode.
This patch explain various device tree properties required for AIC driver
