    ARM: imx6: convert GPC to stacked domains · b923ff6a
    Marc Zyngier authored Feb 23, 2015
    
    
    IMX6 has been (ab)using the gic_arch_extn to provide
    wakeup from suspend, and it makes a lot of sense to convert
    this code to use stacked domains instead.
    
    This patch does just this, updating the DT files to actually
    reflect what the HW provides.
    
    BIG FAT WARNING: because the DTs were so far lying by not
    exposing the fact that the GPC block is actually the first
    interrupt controller in the chain, kernels with this patch
    applied wont have any suspend-resume facility when booted
    with old DTs, and old kernels with updated DTs won't even boot.
