+* Qualcomm Technologies, Inc. MSM Camera FD
+
+The MSM camera Face Detection device provides dependency definitions
+for enabling Camera FD HW. MSM camera FD is implemented in multiple
+device nodes. The root FD device node has properties defined to hint
+the driver about the FD HW nodes available during the probe sequence.
+Each node has multiple properties defined for interrupts, clocks and
+regulators.
+
+=======================
+Required Node Structure
+=======================
+FD root interface node takes care of the handling Face Detection high level
+driver handling and controls underlying FD hardware present.
+
+- compatible
+ Usage: required
+ Value type: <string>
+ Definition: Should be "qcom,cam-fd".
+
+- compat-hw-name
+ Usage: required
+ Value type: <string>
+ Definition: Should be "qcom,fd".
+
+- num-fd
+ Usage: required
+ Value type: <u32>
+ Definition: Number of supported FD HW blocks.
+
+Example:
+ qcom,cam-fd {
+ compatible = "qcom,cam-fd";
+ compat-hw-name = "qcom,fd";
+ num-fd = <1>;
+ };
+
+=======================
+Required Node Structure
+=======================
+FD Node provides interface for Face Detection hardware driver
+about the device register map, interrupt map, clocks, regulators.

+
+- reg-cam-base
+ Usage: optional
+ Value type: <u32>

+ to Camera base register space.
