+* Qualcomm Technologies, Inc. MSM Camera VFE
+
+Camera VFE device provides the definitions for enabling
+the VFE hardware. It also provides the functions for the client
+to control the VFE hardware.
+
+=======================
+Required Node Structure
+=======================
+The VFE device is described in one level of the device node.
+
+======================================
+First Level Node - CAM VFE device
+======================================
+Required properties:
+- compatible
+  Usage: required
+  Value type: <string>
+  Definition: Should specify the compatibility string for matching the
+	driver. e.g. "qcom,vfe480", "qcom,vfe175", "qcom,vfe170", "qcom,vfe175_130",
+	"qcom,vfe-lite480", "qcom,vfe-lite175", "qcom,vfe-lite175_130", "qcom,vfe-lite170".
+
+- cell-index
+  Usage: required
+  Value type: <u32>
+  Definition: Should specify the hardware index id.
+
+- reg-names
+  Usage: required
+  Value type: <string>
+  Definition: Should specify the name of the register block.
+
+- reg
+  Usage: required
+  Value type: <u32>
+  Definition: Register values.
+
+- interrupt-names
+  Usage: Required
+  Value type: <string>
+  Definition: Name of the interrupt.
+
+- interrupts
+  Usage: Required
+  Value type: <u32>
+  Definition: Interrupt associated with VFE HW.
+
+- regulator-names
+  Usage: required
+  Value type: <string>
+  Definition: Name of the regulator resources for VFE HW.
+
+- xxxx-supply
+  Usage: required
+  Value type: <phandle>
+  Definition: Regulator reference corresponding to the names listed in
+	"regulator-names".
+
+- clock-names
+  Usage: required
+  Value type: <string>
+  Definition: List of clock names required for VFE HW.
+
+- clocks
+  Usage: required
+  Value type: <phandle>
+  Definition: List of clocks used for VFE HW.
+
+- clock-rates
+  Usage: required
+  Value type: <u32>
+  Definition: List of clocks rates.
+
+- src-clock-name
+  Usage: required
+  Value type: <string>
+  Definition: Source clock name.
+
+Optional properties:
+- clock-names-option
+  Usage: optional
+  Value type: <string>
+  Definition: Optional clock names.
+
+- clocks-option
+  Usage: required if clock-names-option defined
+  Value type: <phandle>
+  Definition: List of optinal clocks used for VFE HW.
+
+- clock-rates-option
+  Usage: required if clock-names-option defined
+  Value type: <u32>
+  Definition: List of clocks rates for optional clocks.
+
+- clock-control-debugfs
+  Usage: optional
+  Value type: <string>
+  Definition: Enable/Disable clk rate control.
+
+- qcom,cam-cx-ipeak:
+  Usage: optional
+  Value type: <phandle bit>
+	phandle - phandle of CX Ipeak device node
+	bit     - Every bit corresponds to a client of CX Ipeak
+  Definition: CX Ipeak is a mitigation scheme which throttles camera frequency
+	if all the clients are running at their respective threshold
+	frequencies to limit CX peak current.
+	driver in the relevant register.
