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.
Interrupt Aggregator
+-----------------------------------------+
| Intmap VINT |
| +--------------+ +------------+ |
m ------>| | vint | bit | | 0 |.....|63| vint0 |
. | +--------------+ +------------+ | +------+
. | . . | | HOST |
Globalevents ------>| . . |------>| IRQ |
. | . . | | CTRL |
. | . . | +------+
n ------>| +--------------+ +------------+ |
| | vint | bit | | 0 |.....|63| vintx |
| +--------------+ +------------+ |
| |
+-----------------------------------------+
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.
Example:
--------
main_udmass_inta: interrupt-controller@33d00000 {
compatible = "ti,sci-inta";
reg = <0x0 0x33d00000 0x0 0x100000>;

msi-controller;
interrupt-parent = <&main_navss_intr>;
ti,sci = <&dmsc>;

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.
Interrupt Router
+----------------------+
| Inputs Outputs |
+-------+ | +------+ +-----+ |
| GPIO |----------->| | irq0 | | 0 | | Host IRQ
+-------+ | +------+ +-----+ | controller
| . . | +-------+
+-------+ | . . |----->| IRQ |
| INTA |----------->| . . | +-------+
+-------+ | . +-----+ |
| +------+ | N | |
| | irqM | +-----+ |
| +------+ |
| |
+----------------------+
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:
Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
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:
https://downloads.ti.com/tisci/esd/latest/2_tisci_msgs/rm/rm_irq.html
Example:
--------
The following example demonstrates both interrupt router node and the consumer
node(main gpio) on the AM654 SoC:
main_intr: interrupt-controller0 {
compatible = "ti,sci-intr";
ti,intr-trigger-type = <1>;
interrupt-controller;
interrupt-parent = <&gic500>;
#interrupt-cells = <2>;
ti,sci = <&dmsc>;
ti,sci-dst-id = <56>;
ti,sci-rm-range-girq = <0x1>;
};
main_gpio0: gpio@600000 {
...
interrupt-parent = <&main_intr>;
interrupts = <57 256>, <57 257>, <57 258>,
<57 259>, <57 260>, <57 261>;
...
};
