Texas Instruments K3 Interrupt Aggregator
|
||||
=========================================
|
||||
|
||||
The Interrupt Aggregator (INTA) provides a centralized machine
|
||||
which handles the termination of system events to that they can
|
||||
be coherently processed by the host(s) in the system. A maximum
|
||||
of 64 events can be mapped to a single interrupt.
|
||||
|
||||

| +--------------+ +------------+ |
|
||||
| |
|
||||
+-----------------------------------------+
|
||||
|
||||
Configuration of these Intmap registers that maps global events to vint is done
|
||||
by a system controller (like the Device Memory and Security Controller on K3
|
||||
AM654 SoC). Driver should request the system controller to get the range
|
||||
of global events and vints assigned to the requesting host. Management
|
||||
of these requested resources should be handled by driver and requests
|
||||
system controller to map specific global event to vint, bit pair.
|
||||
|
||||
Communication between the host processor running an OS and the system
|
||||
controller happens through a protocol called TI System Control Interface
|
||||
(TISCI protocol). For more details refer:
|
||||
Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
|
||||
|
||||
TISCI Interrupt Aggregator Node:
|
||||
-------------------------------
|
||||
- compatible: Must be "ti,sci-inta".
|
||||
- reg: Should contain registers location and length.
|
||||
- interrupt-controller: Identifies the node as an interrupt controller
|
||||
- msi-controller: Identifies the node as an MSI controller.
|
||||
- interrupt-parent: phandle of irq parent.
|
||||
- ti,sci: Phandle to TI-SCI compatible System controller node.
|
||||
- ti,sci-dev-id: TISCI device ID of the Interrupt Aggregator.
|
||||
- ti,sci-rm-range-vint: Array of TISCI subtype ids representing vints(inta
|
||||
outputs) range within this INTA, assigned to the
|
||||
requesting host context.
|
||||
- ti,sci-rm-range-global-event: Array of TISCI subtype ids representing the
|
||||
global events range reaching this IA and are assigned
|
||||
to the requesting host context.

Texas Instruments K3 Interrupt Router
|
||||
=====================================
|
||||
|
||||
The Interrupt Router (INTR) module provides a mechanism to mux M
|
||||
interrupt inputs to N interrupt outputs, where all M inputs are selectable
|
||||
to be driven per N output. An Interrupt Router can either handle edge triggered
|
||||
or level triggered interrupts and that is fixed in hardware.
|
||||

||||

+----------------------+
|

|
||||
There is one register per output (MUXCNTL_N) that controls the selection.
|
||||
Configuration of these MUXCNTL_N registers is done by a system controller
|
||||
(like the Device Memory and Security Controller on K3 AM654 SoC). System
|
||||
controller will keep track of the used and unused registers within the Router.
|
||||
Driver should request the system controller to get the range of GIC IRQs
|
||||
assigned to the requesting hosts. It is the drivers responsibility to keep
|
||||
track of Host IRQs.
|
||||
|

Communication between the host processor running an OS and the system
|
||||
controller happens through a protocol called TI System Control Interface
|
||||
(TISCI protocol). For more details refer:

TISCI Interrupt Router Node:
|
||||
----------------------------
|
||||
Required Properties:
|
||||
- compatible: Must be "ti,sci-intr".
|
||||
- ti,intr-trigger-type: Should be one of the following:
|
||||
1: If intr supports edge triggered interrupts.
|
||||
4: If intr supports level triggered interrupts.
|
||||
- interrupt-controller: Identifies the node as an interrupt controller
|
||||
- #interrupt-cells: Specifies the number of cells needed to encode an
|
||||
interrupt source. The value should be 2.
|
||||
First cell should contain the TISCI device ID of source
|
||||
Second cell should contain the interrupt source offset
|
||||
within the device.
|
||||
- ti,sci: Phandle to TI-SCI compatible System controller node.
|
||||
- ti,sci-dst-id: TISCI device ID of the destination IRQ controller.
|
||||
- ti,sci-rm-range-girq: Array of TISCI subtype ids representing the host irqs
|
||||
assigned to this interrupt router. Each subtype id
|
||||
corresponds to a range of host irqs.
|
||||
|
||||
For more details on TISCI IRQ resource management refer:

||||

The following example demonstrates both interrupt router node and the consumer
|

ti,sci-dst-id = <56>;
|
||||
ti,sci-rm-range-girq = <0x1>;
|

};

* Sony 1/2.5-Inch 8.51Mp CMOS Digital Image Sensor
|
||||
|
||||
The Sony imx274 is a 1/2.5-inch CMOS active pixel digital image sensor with
|
||||
an active array size of 3864H x 2202V. It is programmable through I2C
|
||||
interface. The I2C address is fixed to 0x1a as per sensor data sheet.
|
||||
Image data is sent through MIPI CSI-2, which is configured as 4 lanes
|
||||
at 1440 Mbps.
|
||||
|
||||
|
||||
Required Properties:
|
||||
- compatible: value should be "sony,imx274" for imx274 sensor
|
||||
- reg: I2C bus address of the device
|
||||
|
||||
Optional Properties:
|
||||
- reset-gpios: Sensor reset GPIO
|
||||
- clocks: Reference to the input clock.
|
||||
- clock-names: Should be "inck".
|
||||
- VANA-supply: Sensor 2.8v analog supply.
|
||||
- VDIG-supply: Sensor 1.8v digital core supply.
|
||||
- VDDL-supply: Sensor digital IO 1.2v supply.
|
||||
|
||||
The imx274 device node should contain one 'port' child node with
|
||||
an 'endpoint' subnode. For further reading on port node refer to
|
||||
Documentation/devicetree/bindings/media/video-interfaces.txt.
|
||||

||||
Example:
|
||||
sensor@1a {
|
||||
compatible = "sony,imx274";
|
||||
reg = <0x1a>;
|
||||
#address-cells = <1>;

This capability enables a guest to set information about its control program

||||
system/firmware service events, providing additional data about the guest
|
||||
environments running on the machine.
|
||||
|
||||
The information is associated with the DIAGNOSE 0x318 instruction, which sets
|
||||
an 8-byte value consisting of a one-byte Control Program Name Code (CPNC) and
|
||||
a 7-byte Control Program Version Code (CPVC). The CPNC determines what
|
||||
environment the control program is running in (e.g. Linux, z/VM...), and the
|
||||
CPVC is used for information specific to OS (e.g. Linux version, Linux
|
||||
distribution...)
|
||||
|
||||
If this capability is available, then the CPNC and CPVC can be synchronized
|
||||
between KVM and userspace via the sync regs mechanism (KVM_SYNC_DIAG318).
