Vincent Donnefort 9d2ea95a59 ARM: mvebu: add broken-idle option
The broken-idle option can be activated from the coherency-fabric DT
node. This property allows to disable the idle capability, when the
hardware doesn't support it, like the Seagate Personal Cloud boards.

Coherency fabric
----------------
Available on Marvell SOCs: Armada 370, Armada 375, Armada 38x and Armada XP
Required properties:
- compatible: the possible values are:
* "marvell,coherency-fabric", to be used for the coherency fabric of
the Armada 370 and Armada XP.
* "marvell,armada-375-coherency-fabric", for the Armada 375 coherency
fabric.
* "marvell,armada-380-coherency-fabric", for the Armada 38x coherency
fabric.
- reg: Should contain coherency fabric registers location and
length.
* For "marvell,coherency-fabric", the first pair for the coherency
fabric registers, second pair for the per-CPU fabric registers.
* For "marvell,armada-375-coherency-fabric", only one pair is needed
for the per-CPU fabric registers.
* For "marvell,armada-380-coherency-fabric", only one pair is needed
for the per-CPU fabric registers.
Optional properties:
- broken-idle: boolean to set when the Idle mode is not supported by the
hardware.
Examples:
coherency-fabric@d0020200 {
compatible = "marvell,coherency-fabric";
reg = <0xd0020200 0xb0>,
<0xd0021810 0x1c>;
};
coherency-fabric@21810 {
compatible = "marvell,armada-375-coherency-fabric";
reg = <0x21810 0x1c>;
};
