1Broadcom iProc Multi Host Bridge (MHB)
2
3Certain Broadcom iProc SoCs have a multi host bridge (MHB) block that controls
4the connection and configuration of 1) internal PCIe serdes; 2) PCIe endpoint
5interface; 3) access to the Nitro (network processing) engine
6
7This node allows access to these MHB registers via syscon.
8
9Required properties:
10- compatible: should contain:
11		"brcm,sr-mhb", "syscon" for Stingray
12- reg: base address and range of the MHB registers
13
14Example:
15	mhb: syscon@60401000 {
16		compatible = "brcm,sr-mhb", "syscon";
17		reg = <0 0x60401000 0 0x38c>;
18	};
