On dm81xx we have 128 interrupts like am33xx has. Let's add compatible flags for dm814x and dm816x, and document the existing binding. As the dm81xx are booting in device tree only mode, we can now also remove ti81xx_init_irq() legacy function.

Omap2/3 intc controller
|
|
|
|
On TI omap2 and 3 the intc interrupt controller can provide
|
|
96 or 128 IRQ signals to the ARM host depending on the SoC.
|
|
|
|
Required Properties:
|
|
- compatible: should be one of
|
|
"ti,omap2-intc"
|
|
"ti,omap3-intc"
|
|
"ti,dm814-intc"
|
|
"ti,dm816-intc"
|
|
"ti,am33xx-intc"
|
|
|
|
- interrupt-controller : Identifies the node as an interrupt controller
|
|
- #interrupt-cells : Specifies the number of cells needed to encode interrupt
|
|
source, should be 1 for intc
|
|
- interrupts: interrupt reference to primary interrupt controller
|
|
|
|
Please refer to interrupts.txt in this directory for details of the common
|
|
Interrupt Controllers bindings used by client devices.
|
|
|
|
Example:
|
|
intc: interrupt-controller@48200000 {
|
|
compatible = "ti,omap3-intc";
|
|
interrupt-controller;
|
|
#interrupt-cells = <1>;
|
|
reg = <0x48200000 0x1000>;
|
|
};
