1 Marvell Armada AP806 System Controller
2 ======================================
4 The AP806 is one of the two core HW blocks of the Marvell Armada 7K/8K
5 SoCs. It contains a system controller, which provides a number
6 registers giving access to numerous features: clocks, pin-muxing and
7 many other SoC configuration items. This DT binding allows to describe
8 this system controller.
10 For the top level node:
11 - compatible: must be: "syscon", "simple-mfd";
12 - reg: register area of the AP806 system controller
18 The Device Tree node representing the AP806 system controller provides
21 - 0: clock of CPU cluster 0
22 - 1: clock of CPU cluster 1
23 - 2: fixed PLL at 1200 Mhz
24 - 3: MSS clock, derived from the fixed PLL
28 - compatible: must be: "marvell,ap806-clock"
29 - #clock-cells: must be set to 1
34 For common binding part and usage, refer to
35 Documentation/devicetree/bindings/pinctrl/marvell,mvebu-pinctrl.txt.
38 - compatible must be "marvell,ap806-pinctrl",

42 only for more detailed description in this document.
