* Marvell Berlin CPU control bindings
|
||||
|
||||
CPU control register allows various operations on CPUs, like resetting them
|

independently.
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "marvell,berlin-cpu-ctrl"
|
||||
- reg: address and length of the register set
|
||||
|

Example:
|
||||
|
||||
cpu-ctrl@f7dd0000 {
|
||||
compatible = "marvell,berlin-cpu-ctrl";
|
