1DDR PHY Front End (DPFE) for Broadcom STB
2=========================================
3
4DPFE and the DPFE firmware provide an interface for the host CPU to
5communicate with the DCPU, which resides inside the DDR PHY.
6
7There are three memory regions for interacting with the DCPU. These are
8specified in a single reg property.
9
10Required properties:
11  - compatible: must be "brcm,bcm7271-dpfe-cpu", "brcm,bcm7268-dpfe-cpu"
12    or "brcm,dpfe-cpu"
13  - reg: must reference three register ranges
14      - start address and length of the DCPU register space
15      - start address and length of the DCPU data memory space
16      - start address and length of the DCPU instruction memory space
17  - reg-names: must contain "dpfe-cpu", "dpfe-dmem", and "dpfe-imem";
18        they must be in the same order as the register declarations
19
20Example:
21	dpfe_cpu0: dpfe-cpu@f1132000 {
22		compatible = "brcm,bcm7271-dpfe-cpu", "brcm,dpfe-cpu";
23		reg =  <0xf1132000 0x180
24			0xf1134000 0x1000
25			0xf1138000 0x4000>;
26		reg-names = "dpfe-cpu", "dpfe-dmem", "dpfe-imem";
27	};
