Linus Walleij a67202583f ARM: integrator: get the LM interrupts from DT
The OF/DT boot path needs to get the LM (Logical Module)
IRQs from the device tree for coherency. This augments the
DT syscon node to contain these IRQs and alter the DT LM
code to get them from there.

ARM Integrator/AP (Application Platform) and Integrator/CP (Compact Platform)
-----------------------------------------------------------------------------
ARM's oldest Linux-supported platform with connectors for different core
tiles of ARMv4, ARMv5 and ARMv6 type.
Required properties (in root node):
compatible = "arm,integrator-ap"; /* Application Platform */
compatible = "arm,integrator-cp"; /* Compact Platform */
FPGA type interrupt controllers, see the versatile-fpga-irq binding doc.
Required nodes:
In the root node the Integrator/CP must have a /cpcon node pointing
to the CP control registers, and the Integrator/AP must have a
/syscon node pointing to the Integrator/AP system controller.
The AP syscon node must include the logic module interrupts, stated
in order of module instance <module 0, module 1, module 2 ...>
example:
/dts-v1/;
/include/ "integrator.dtsi"
/ {
model = "ARM Integrator/AP";
compatible = "arm,integrator-ap";
syscon {
/* AP system controller registers */
reg = <0x11000000 0x100>;
interrupt-parent = <&pic>;
/* These are the logic module IRQs */
interrupts = <9>, <10>, <11>, <12>;
};
};
ARM Versatile Application and Platform Baseboards
-------------------------------------------------
ARM's development hardware platform with connectors for customizable
core tiles. The hardware configuration of the Versatile boards is
highly customizable.
Required properties (in root node):
compatible = "arm,versatile-ab"; /* Application baseboard */
compatible = "arm,versatile-pb"; /* Platform baseboard */
Interrupt controllers:
- VIC required properties:
compatible = "arm,versatile-vic";
interrupt-controller;
#interrupt-cells = <1>;
- SIC required properties:
compatible = "arm,versatile-sic";
interrupt-controller;
#interrupt-cells = <1>;
