From: Akhil Goyal <akhil.goyal@xxxxxxxxxxxxx> 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(AD9361 in this case). A combination of AIC lane and AD 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 and AD9361 drivers.
