| 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 gatable 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
| gatable clocks.
| - The second cell identifies the particular core clock or gatable
| 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
| - Gatable 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" or "marvell,armada-8k-cps-pinctrl"
| depending on the specific variant of the SoC being used.
|
| Available mpp pins/groups and functions:
| Note: brackets (x) are not part of the mpp name for marvell,function and given
| only for more detailed description in this document.

| ===================
|
| Thermal:
| --------
|
| The thermal IP can probe the temperature all around the processor. It
| may feature several channels, each of them wired to one sensor.
|
| For common binding part and usage, refer to
| Documentation/devicetree/bindings/thermal/thermal.txt
|
| Required properties:
| - compatible: must be one of:
| * marvell,armada-cp110-thermal
| - reg: register range associated with the thermal functions.
|
| Optional properties:
| - #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer
| to this IP and represents the channel ID. There is one sensor per
| channel. O refers to the thermal IP internal channel.
|
| Example:
| CP110_LABEL(syscon1): system-controller@6f8000 {
| compatible = "syscon", "simple-mfd";
| reg = <0x6f8000 0x1000>;
|
| CP110_LABEL(thermal): thermal-sensor@70 {
| compatible = "marvell,armada-cp110-thermal";
| reg = <0x70 0x10>;
| #thermal-sensor-cells = <1>;
| };
| };
