9 Boards with a SoC of the Marvell Berlin family
10 shall have the following properties:
11
12 * Required root node properties:
13 compatible: must contain "marvell,berlin"
14
15 In addition, the above compatible shall be ext
16 SoC and board used. Currently known SoC compat
17 "marvell,berlin2" for Marvell Armada
18 "marvell,berlin2cd" for Marvell Armada
19 "marvell,berlin2ct" for Marvell Armada
20 "marvell,berlin2q" for Marvell Armada
21 "marvell,berlin3" for Marvell Armada

23 * Example:
24
25 / {
26 model = "Sony NSZ-GS7";
27 compatible = "sony,nsz-gs7", "marvell,

29 ...
30 }
31
32 * Marvell Berlin CPU control bindings
33
34 CPU control register allows various operations
35 independently.
36
37 Required properties:
38 - compatible: should be "marvell,berlin-cpu-ct
39 - reg: address and length of the register set
40
41 Example:
42
43 cpu-ctrl@f7dd0000 {
44 compatible = "marvell,berlin-cpu-ctrl"
45 reg = <0xf7dd0000 0x10000>;
46 };
47
48 * Marvell Berlin2 chip control binding
49
50 Marvell Berlin SoCs have a chip control regist
51 individual registers dealing with pinmux, padm
52 CPU boot address. Unfortunately, the individua
53 chip control registers, so there should be a s
54 different functions which are described below.
55
56 Required properties:
57 - compatible:
58 * the first and second values must be:
59 "simple-mfd", "syscon"
60 - reg: address and length of following registe
61 BG2/BG2CD: chip control register set
62 BG2Q: chip control register set and cpu pll
63
64 * Marvell Berlin2 system control binding
65
66 Marvell Berlin SoCs have a system control regi
67 individual registers dealing with pinmux, padm
68
69 Required properties:
70 - compatible:
71 * the first and second values must be:
72 "simple-mfd", "syscon"
73 - reg: address and length of the system contro
74
75 Example:
76
77 chip: chip-control@ea0000 {
78 compatible = "simple-mfd", "syscon";
79 reg = <0xea0000 0x400>;
80
81 /* sub-device nodes */
82 };
83
84 sysctrl: system-controller@d000 {
85 compatible = "simple-mfd", "syscon";
86 reg = <0xd000 0x100>;
87
88 /* sub-device nodes */
89 };
