* Qualcomm Technologies, Inc. MSM Camera CSID PPI

Camera CSID PPI device provides the definitions for enabling
the CSID PPI hardware. It also provides the functions for the client
to control the CSID PPI hardware.

=======================
Required Node Structure
=======================
The CSID PPI device is described in one level of the device node.

Example:

	cam_ppi0: qcom,ppi0@5cb3000 {
		cell-index = <0>;
		compatible = "qcom,ppi100";
		reg-names = "ppi0";
		reg = <0x5cb3000 0x200>;
		interrupt-names = "ppi0";
		interrupts = <GIC_SPI 214 IRQ_TYPE_EDGE_RISING>;
		clocks = <&gcc GCC_CAMSS_CPHY_0_CLK>;
		clock-names = "gcc_camss_cphy_0_clk";
		clock-cntl-level = "svs";
		clock-rates = <0>;
		status = "ok";
	};
