The MSM AIS IFE driver provides the definitions for enabling

the Camera IFE hadware for Automotive usecase. It provides the

functions for the Client to control the IFE hardware.



=======================

Required Node Structure

=======================

The Camera AIS IFE device is described in one level of device node.



==================================

First Level Node - AIS IFE device

==================================

- compatible

  Usage: required

  Value type: <string>

  Definition: Should be "qcom,ais-ife".



- arch-compat

  Usage: required

  Value type: <string>

  Definition: Should be "ife".



- cell-index

  Usage: required

  Value type: <u32>

  Definition: Should specify the hardware index id.



Example:



	qcom,ais-ife0 {

		compatible = "qcom,ais-ife";

		cell-index = <0>;

		status = "ok";

	};
