This patchset add support for GPIO interrupt controller of Meson-S4 SoC Which has something different with current other meson chips. To support the new chips, current gpio irqchip driver need to rework as below: 1. support more than 8 gpio irq lines. 2. add a set trigger type callback function. With above work, add support for S4 gpio irqchip Changes since v2 at [1]: - rework nr channels allocations - move old controller set_type to a callback Changes since v1 at [0]: - fix leaking issue - fix some typos - change implementation of new feature.
