Add a function to initialize the OMAP2/3 interrupt controller (INTC) using a device tree node. This version take advantage of the new irq_domain_add_legacy API. Replace some printk() with the proper pr_ macro.

* OMAP Interrupt Controller
|
|
|
|
OMAP2/3 are using a TI interrupt controller that can support several
|
|
configurable number of interrupts.
|
|
|
|
Main node required properties:
|
|
|
|
- compatible : should be:
|
|
"ti,omap2-intc"
|
|
- interrupt-controller : Identifies the node as an interrupt controller
|
|
- #interrupt-cells : Specifies the number of cells needed to encode an
|
|
interrupt source. The type shall be a <u32> and the value shall be 1.
|
|
|
|
The cell contains the interrupt number in the range [0-128].
|
|
- ti,intc-size: Number of interrupts handled by the interrupt controller.
|
|
- reg: physical base address and size of the intc registers map.
|
|
|
|
Example:
|
|
|
|
intc: interrupt-controller@1 {
|
|
compatible = "ti,omap2-intc";
|
|
interrupt-controller;
|
|
#interrupt-cells = <1>;
|
|
ti,intc-size = <96>;
|
|
reg = <0x48200000 0x1000>;
|
|
};
