-Marvell Armada AP806 System Controller
-======================================
-
-The AP806 is one of the two core HW blocks of the Marvell Armada 7K/8K
-SoCs. It contains system controllers, which provide several registers
-giving access to numerous features: clocks, pin-muxing and many other
-SoC configuration items. This DT binding allows to describe these
-system controllers.
-
-For the top level node:
- - compatible: must be: "syscon", "simple-mfd";
- - reg: register area of the AP806 system controller
-
-SYSTEM CONTROLLER 0
-===================
-
-Clocks:
--------
-
-
-The Device Tree node representing the AP806/AP807 system controller
-provides a number of clocks:
-
- - 0: reference clock of CPU cluster 0
- - 1: reference clock of CPU cluster 1
- - 2: fixed PLL at 1200 Mhz
- - 3: MSS clock, derived from the fixed PLL
-
-Required properties:
-
- - compatible: must be one of:
