Marvell Armada CP110 System Controller
======================================

The CP110 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 CP110 system controller

SYSTEM CONTROLLER 0
===================

Clocks:
-------

The Device Tree node representing this System Controller 0 provides a
number of clocks:

 - a set of core clocks
 - a set of gateable clocks

Those clocks can be referenced by other Device Tree nodes using two
cells:
 - The first cell must be 0 or 1. 0 for the core clocks and 1 for the
   gateable clocks.
 - The second cell identifies the particular core clock or gateable
   clocks.

The following clocks are available:
 - Core clocks
   - 0 0	APLL
   - 0 1	PPv2 core
   - 0 2	EIP
   - 0 3	Core
   - 0 4	NAND core
   - 0 5	SDIO core
 - Gateable clocks
   - 1 0	Audio
   - 1 1	Comm Unit
   - 1 2	NAND
   - 1 3	PPv2
   - 1 4	SDIO
   - 1 5	MG Domain
   - 1 6	MG Core
   - 1 7	XOR1
   - 1 8	XOR0
   - 1 9	GOP DP
   - 1 11	PCIe x1 0
   - 1 12	PCIe x1 1
   - 1 13	PCIe x4
   - 1 14	PCIe / XOR
   - 1 15	SATA
   - 1 16	SATA USB
   - 1 17	Main
   - 1 18	SD/MMC/GOP
   - 1 21	Slow IO (SPI, NOR, BootROM, I2C, UART)
   - 1 22	USB3H0
   - 1 23	USB3H1
   - 1 24	USB3 Device
   - 1 25	EIP150
   - 1 26	EIP197

Required properties:

 - compatible: must be:
     "marvell,cp110-clock"
 - #clock-cells: must be set to 2

Pinctrl:
--------

For common binding part and usage, refer to the file
Documentation/devicetree/bindings/pinctrl/marvell,mvebu-pinctrl.txt.

Required properties:

- compatible: "marvell,armada-7k-pinctrl", "marvell,armada-8k-cpm-pinctrl",
  "marvell,armada-8k-cps-pinctrl" or "marvell,cp115-standalone-pinctrl"
  depending on the specific variant of the SoC being used.
