This patch reworks wake-up interrupt handling in pinctrl-exynos driver,
so each pin bank, which provides wake-up interrupts, has its own IRQ
domain.
Information about whether given pin bank provides wake-up interrupts,
how many and whether they are separate or muxed are parsed from device
tree.
It gives following advantages:
- interrupts can be specified in device tree in a more readable way,
e.g. :
device {
/* ... */
interrupt-parent = <&gpx2>;
interrupts = <4 0>;
/* ... */
};
- the amount and layout of interrupts is not hardcoded in the code
anymore, but defined in SoC-specific structure
- bank and pin of each wake-up interrupt can be easily identified, to
allow operations, such as setting the pin to EINT function, from
irq_set_type() callback
