From: Akhil Goyal <akhil.goyal@xxxxxxxxxxxxx> RF signal path is integral part of any system that transmits/receives RF (radio frequency) signals. In these systems Data is processed/converted to IQ samples (digital representation a RF signal) and passed to a RFIC (RF PHY) which converts the digital RF signal (IQ samples) to analog and transmits over antenna. Typically The signal path consists of multiple components: Antenna controller <-> vector signal processors <-> RFIC <-> Antenna Each of these components have specific functionalities: 1. Antenna controller: Framing of digital IQ data into protocol specific frames. 2. vector signal processors: For conditioning of signal. 3. RFIC : converts digital IQ data to analog signal which is transmitted/received on/from Air. Also it is desirable to control the complete signal path, for example: bringing the complete signal path up/down etc. The radio device framework introduces a way to accommodate the RF signal paths. One signal path is represented as a RF device (rf0, rf1 etc), and it can contain multiple components which have their individual vendor specific drivers. The framework provides mechanism by which individual components can register with RF framework, and the framework will handle the binding of individual component devices to a RF device. RF device exports the control interfaces to user space, and this user space interface is independent of component (vendor specific) drivers. This patch set include 1. RF Interface: Independent of phy or antenna controller. 2. AIC driver: Antenna interface Controller(AIC) of Hetrogenous SOC's like BSC9131, BSC9132 3. AD9361 driver: RF Phy driver for Analog Devices(ADI) chip(AD9361) 4. Device tree bindings for AIC and ADI nodes. 5. Device tree changes for BSC9131 This framework will be re-sent for drivers/ folder after it gets approval for staging.
