[PATCH 1/6 v3] ARM: integrator: get the LM interrupts from DT

[Linus Walleij]

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.

 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";
