+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.

+SYSTEM CONTROLLER 1
+===================
+
+Thermal:
+--------
+
+The thermal IP can probe the temperature all around the processor. It
+may feature several channels, each of them wired to one sensor.
+
+It is possible to setup an overheat interrupt by giving at least one
+critical point to any subnode of the thermal-zone node.
+
+For common binding part and usage, refer to
+Documentation/devicetree/bindings/thermal/thermal*.yaml
+
+Required properties:
+- compatible: must be one of:
+ * marvell,armada-cp110-thermal
+- reg: register range associated with the thermal functions.
+
+Optional properties:
+- interrupts-extended: overheat interrupt handle. Should point to
+ a line of the ICU-SEI irqchip (116 is what is usually used by the
+ firmware). The ICU-SEI will redirect towards interrupt line #37 of the
+ AP SEI which is shared across all CPs.
+ See interrupt-controller/interrupts.txt
+- #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>;
+ interrupts-extended = <&CP110_LABEL(icu_sei) 116 IRQ_TYPE_LEVEL_HIGH>;
+ #thermal-sensor-cells = <1>;
+ };
+};
