pinctrl: exynos: Use one IRQ domain per pin bank
Instead of registering one IRQ domain for all pin banks of a pin controller, this patch implements registration of per-bank domains. At a cost of a little memory overhead (~2.5KiB for all GPIO interrupts of Exynos4x12) it simplifies driver code and device tree sources, because GPIO interrupts can be now specified per banks. Example: device { /* ... */ interrupt-parent = <&gpa1>; interrupts = <3 0>; /* ... */ }; Signed-off-by: Tomasz Figa <t.figa@samsung.com> Reviewed-by: Kyungmin Park <kyungmin.park@samsung.com> Acked-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
