I think it mostly holds: GPIOLIB_IRQCHIP should always be used if there is a reasonably straight-forward interrupts whether cascaded or hierarchical. Very few exceptions there. If there is one IRQ line per GPIO line, the hierarchical support should be used as outlined. GPIO_REGMAP should be mostly (famous last words) orthogonal.
