    Subject[PATCH v2 3/4] binding: Add device tree bindings for freescale AIC
    Date
    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

    +Freescale Antenna Interface Controller
    +
    +AIC is the antenna interface controller found in bsc913x
    +family of SOCs. It supports NCDMA, WCDMA-FDD, LTE-FDD, LTE-TDD
    +and GSM-SNIFF network modes. AIC has multiple lanes on which RFICs
    +can be connected. And AIC supports 4 RFICs working simultaneously.
    +
    +Required Properties:
    +- #address-cells : should be 1
    +- #size-cells : should be 1
    +- compatible : should be fsl,bsc9131-aic or fsl,bsc9132-aic or both
    +- reg : offset and length of common register set of AIC
    +- interrupts : For AIC, first is capture complete interrupt
    + second is dsp general interrupt
    +aic node can have multiple sub nodes of aiclanes for each lane.
    +- aiclane : Required Properties
    + - reg : offset and length of common register set of AIC lane
    + - lane_id : it can be 0, 1, 2, 3, 4, 5
    + - interrupts : lane specific TTI interrupt line
    +
    +For Example:
    +
    +aic@50000 {
    + #address-cells = <1>;
    + #size-cells = <1>;
    + compatible = "fsl,bsc9131-aic", "fsl,bsc9132-aic";
    + reg = <0x50000 0x200>;
    + interrupts = <49 2 0 0 53 2 0 0>;
    + lane0: aiclane@200 {
    + reg = <0x200 0x200>;
    + lane_id = <0>;
    + interrupts = <45 2 0 0>;
    + };
    +
    + lane1: aiclane@400 {
    + reg = <0x400 0x200>;
    + lane_id = <1>;
    + interrupts = <46 2 0 0>;
    + };
    +
    + lane2: aiclane@600 {
    + reg = <0x600 0x200>;
    + lane_id = <2>;
    + interrupts = <47 2 0 0>;
    + };
    +};
    +
