-DDR PHY Front End (DPFE) for Broadcom STB
-=========================================
-
-DPFE and the DPFE firmware provide an interface for the host CPU to
-communicate with the DCPU, which resides inside the DDR PHY.
-
-There are three memory regions for interacting with the DCPU. These are
-specified in a single reg property.
-
-Required properties:
- - compatible: must be "brcm,bcm7271-dpfe-cpu", "brcm,bcm7268-dpfe-cpu"
- or "brcm,dpfe-cpu"
- - reg: must reference three register ranges
- - start address and length of the DCPU register space
- - start address and length of the DCPU data memory space
- - start address and length of the DCPU instruction memory space
- - reg-names: must contain "dpfe-cpu", "dpfe-dmem", and "dpfe-imem";
- they must be in the same order as the register declarations
-
-Example:
- dpfe_cpu0: dpfe-cpu@f1132000 {
- compatible = "brcm,bcm7271-dpfe-cpu", "brcm,dpfe-cpu";
- reg = <0xf1132000 0x180
- 0xf1134000 0x1000
- 0xf1138000 0x4000>;
- reg-names = "dpfe-cpu", "dpfe-dmem", "dpfe-imem";
- };
