* Qualcomm Technologies, Inc. MSM Camera OPE

The ope device node has properties defined to hint the driver

about the number of OPE nodes available during the

probe sequence. Each node has multiple properties defined

for interrupts, clocks and regulators.

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

Required Node Structure

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

OPE root interface node takes care of the handling account for number

of OPE devices present on the hardware.

- compatible

  Usage: required

  Value type: <string>

  Definition: Should be "qcom,cam-ope".

- compat-hw-name

  Usage: required

  Value type: <string>

  Definition: Should be "qcom,ope".

- num-ope

  Usage: required

  Value type: <u32>

  Definition: Number of supported OPE HW blocks.

Example:

	qcom,cam-ope {

		compatible = "qcom,cam-ope";

		compat-hw-name = "qcom,ope";

		num-ope = <2>;

		status = "ok";

	};

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

Required Node Structure

OPE Node provides interface for Image Control Processor driver

about the OPE register map, interrupt map, clocks, regulators.

  Usage: optional

  Value type: <u32>

  Definition: Interrupt associated with OPE HW.

- regulator-names

  Usage: required

  Value type: <string>

  Definition: Name of the regulator resources for OPE HW.

- camss-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 CDM HW.

- src-clock-name

  Usage: required

  Value type: <string>

  Definition: Source clock name.

- clock-control-debugfs

  Usage: optional

  Value type: <string>

  Definition: Enable/Disable clk rate control.

- clocks

  Usage: required

  Value type: <phandle>

  Definition: List of clocks used for CDM HW.

- clock-cntl-level

  Usage: required

  Value type: <string>

  Definition: List of strings corresponds clock-rates levels.

  Supported strings: lowsvs, svs, svs_l1, nominal, turbo.
