Subject: [PATCH 4/5] binding: Add device tree bindings for freescale AIC and AD phy
From: Akhil Goyal <akhil.goyal@...escale.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(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.

+- fsl,ad9361-band-grpX : denotes group of LTE/WCDMA bands available for a
+ particular combination of values of pa_en and lna_en gpios.
+ where X can be 1,2,3,4
+ - fsl,ad9361-bands : denotes LTE/WCDMA band numbers for normal DL/UL

+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@...00 {
+ #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>;
+ };
