This binding is intended to represent the interconnect hardware present
in some of the modern SoCs. Currently it consists only of a binding for
the interconnect hardware devices (provider).

+Interconnect Provider Device Tree Bindings
+=========================================
+
+The purpose of this document is to define a common set of generic interconnect
+providers/consumers properties.
+
+
+= interconnect providers =
+
+The interconnect provider binding is intended to represent the interconnect
+controllers in the system. Each provider registers a set of interconnect
+nodes, which expose the interconnect related capabilities of the interconnect
+to consumer drivers. These capabilities can be throughput, latency, priority
+etc. The consumer drivers set constraints on interconnect path (or endpoints)
+depending on the usecase. Interconnect providers can also be interconnect
+consumers, such as in the case where two network-on-chip fabrics interface
+directly
+
+Required properties:
+- compatible : contains the interconnect provider vendor specific compatible
+ string
+- reg : register space of the interconnect controller hardware
+
+Examples:
+
+ snoc: snoc@580000 {
+ compatible = "qcom,msm8916-snoc";
+ reg = <0x580000 0x14000>;
+ clock-names = "bus_clk", "bus_a_clk";
+ clocks = <&rpmcc RPM_SMD_SNOC_CLK>, <&rpmcc
RPM_SMD_SNOC_A_CLK>;
+ status = "okay";
+ };
+ bimc: bimc@400000 {
+ compatible = "qcom,msm8916-bimc";
+ reg = <0x400000 0x62000>;
+ clock-names = "bus_clk", "bus_a_clk";
+ clocks = <&rpmcc RPM_SMD_BIMC_CLK>, <&rpmcc
RPM_SMD_BIMC_A_CLK>;
+ status = "okay";
+ };
+ pnoc: pnoc@500000 {
+ compatible = "qcom,msm8916-pnoc";
+ reg = <0x500000 0x11000>;
+ clock-names = "bus_clk", "bus_a_clk";
+ clocks = <&rpmcc RPM_SMD_PCNOC_CLK>, <&rpmcc
RPM_SMD_PCNOC_A_CLK>;
+ status = "okay";
+ };
