Marvell Armada AP806 System Controller
|
|
======================================
|
|
|
|
The AP806 is one of the two core HW blocks of the Marvell Armada 7K/8K
|
|
SoCs. It contains a system controller, which provides a number
|
|
registers giving access to numerous features: clocks, pin-muxing and
|
|
many other SoC configuration items. This DT binding allows to describe
|
|
this system controller.
|
|
|
|
The Device Tree node representing the AP806 system controller provides
|
|
a number of clocks:
|
|
|
|
- 0: clock of CPU cluster 0
|
|
- 1: clock of CPU cluster 1
|
|
- 2: fixed PLL at 1200 Mhz
|
|
- 3: MSS clock, derived from the fixed PLL
|
|
|
|
Required properties:
|
|
|
|
- compatible: must be:
|
|
"marvell,ap806-system-controller", "syscon"
|
|
- reg: register area of the AP806 system controller
|
|
- #clock-cells: must be set to 1
|
|
- clock-output-names: must be defined to:
|
|
"ap-cpu-cluster-0", "ap-cpu-cluster-1", "ap-fixed", "ap-mss"
|
|
|
|
Example:
|
|
|
|
syscon: system-controller@6f4000 {
|
|
compatible = "marvell,ap806-system-controller", "syscon";
|
|
#clock-cells = <1>;
|
|
clock-output-names = "ap-cpu-cluster-0", "ap-cpu-cluster-1",
|
|
"ap-fixed", "ap-mss";
|
|
reg = <0x6f4000 0x1000>;
|
|
};
