    MIPS: SEAD-3: Fix GIC interrupt specifiers · d3f61634
    Paul Burton authored
    The various interrupt specifiers in the device tree are not in a valid
    format for the MIPS GIC interrupt controller binding. Where each
    interrupt should provide 3 values - GIC_LOCAL or GIC_SHARED, the
    pin number & the type of interrupt - the device tree was only providing
    the pin number. This causes interrupts for those devices to not be used
    when a GIC is present. SEAD-3 systems without a GIC are unaffected since
    the DT fixup code generates interrupt specifiers that are valid for the
    CPU interrupt controller.
    Fix this by adding the GIC_SHARED & IRQ_TYPE_LEVEL_HIGH values to each
    interrupt specifier.
