* arc-uart platform device now populated dynamically, using
of_platform_populate() - applies to any other device whatsoever.
* uart in turn requires incore arc-intc to be also present in DT
* A irq-domain needs to be instantiated for IRQ requests by DT probed
device (e.g. arc-uart)
TODO: switch over to linear irq domain once all devs have been
transitioned to DT

* ARC700 incore Interrupt Controller
|
|
|
|
The core interrupt controller provides 32 prioritised interrupts (2 levels)
|
|
to ARC700 core.
|
|
|
|
Properties:
|
|
|
|
- compatible: "snps,arc700-intc"
|
|
- interrupt-controller: This is an interrupt controller.
|
|
- #interrupt-cells: Must be <1>.
|
|
|
|
Single Cell "interrupts" property of a device specifies the IRQ number
|
|
between 0 to 31
|
|
|
|
intc accessed via the special ARC AUX register interface, hence "reg" property
|
|
is not specified.
|
|
|
|
Example:
|
|
|
|
intc: interrupt-controller {
|
|
compatible = "snps,arc700-intc";
|
|
interrupt-controller;
|
|
#interrupt-cells = <1>;
|
|
};
