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

===================
|
|
|
|
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>;
