This commit improves the Armada XP GP Device Tree description to describe the 3 GPIOs that are used to connect the SoC to the PIC micro-controller that we talk to shutdown the SoC when entering suspend to RAM.

* DT-capable, U-Boot bootloaders provided by Marvell. Some earlier
|
|
* boards were delivered with an older version of the bootloader that
|
|
* left internal registers mapped at 0xd0000000. If you are in this
|
|
* situation, you should either update your bootloader (preferred
|
|
* solution) or the below Device Tree should be adjusted.
