Hi Linus,

This patch add EINT support to the pinctrl driver. We've surveyed
GPIOLIB_IRQCHIP, but we didn't use it because:

- Not every GPIO pin support interrupt.
- EINT use a different numbering to GPIO. eg, from the mt8135 table,
GPIO29 is EINT158. It is more nature & efficient to use EINT number as
hwirq.

+               MTK_EINT_FUNCTION(2, 158),
+               MTK_FUNCTION(0, "GPIO29"),

Joe.C
