pinctrl: samsung: Use per-bank IRQ domain for wake-up interrupts
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 Signed-off-by:Tomasz Figa <t.figa@samsung.com> Reviewed-by:
