The Calxeda system registers are a collection of MMIO register controlling several more general aspects of the SoC. Beside for some power management tasks this node is also somewhat abused as the container for the clock nodes. Add a binding in DT schema format using json-schema.

|
description: |
|
|
The Calxeda Highbank system has a block of MMIO registers controlling
|
|
several generic system aspects. Those can be used to control some power
|
|
management, they also contain some gate and PLL clocks.
