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

Linus Walleij linus.walleij at linaro.org
Thu Oct 3 12:02:57 EDT 2013


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.

 to the CP control registers, and the Integrator/AP must have a
 /syscon node pointing to the Integrator/AP system controller.
