* 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";
reg = <0xf7dd0000 0x10000>;
};
* Marvell Berlin2 chip control binding
Marvell Berlin SoCs have a chip control register set providing several
