-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 interrupt controller.
-- ti,interrupt-ranges: Set of triplets containing ranges that convert
- the INTA output interrupt numbers to parent's
- interrupt number. Each triplet has following entries:
- - First entry specifies the base for vint
- - Second entry specifies the base for parent irqs
- - Third entry specifies the limit
-
-
-Example:
---------
-main_udmass_inta: interrupt-controller@...00000 {
- compatible = "ti,sci-inta";
- reg = <0x0 0x33d00000 0x0 0x100000>;
- interrupt-controller;
- msi-controller;
- interrupt-parent = <&main_navss_intr>;
- ti,sci = <&dmsc>;
- ti,sci-dev-id = <179>;
- ti,interrupt-ranges = <0 0 256>;
-};
