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>;
|
|
};
