Tony Lindgren 19f92b237b irqchip: omap-intc: Fix support for dm814 and dm816
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>;
};
