    ARM: shmobile: INTC External IRQ pin driver on r8a7779 · 8e56e6d5
    Magnus Damm authored
    Update the r8a7779 IRQ code to make use of the
    INTC External IRQ pin driver for external
    interrupt pins IRQ0 -> IRQ3.
    
    The r8a7779 SoC can like older SH SoCs configure
    to use the IRQ0 -> IRQ3 signals as individual
    interrupts or a combined IRL mode.
    
    Without this patch the r8a7779 SoC code does
    not fully support external IRQ pins in individual
    IRQ mode. The r8a7779 PFC code does not yet have
    gpio_to_irq() support so no need to update such
    code.
    
    At this point the DT reference implementations
    are not covered. In the future such code shall
    tie in the INTC External IRQ pin driver via
    DT, so this kind of verbose code is not needed
    for the long term DT case.
