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