This patch we can now make a bit more generic with the recent addition
of interrupts-extended property that's now merged in mainline tree :)
We can optionally pass two interrupts to omap_hsmmc.c where the second
interrupt is either the pinctrl-single wake-up interrupt, or the GPIO
interrupt.
Both the iochain wake interrupt or the GPIO interrupt are available with
request_irq as long as configured in the .dts file. And can both use the
SDIO interrupt handler. The only difference is that the GPIO wake-up
still needs to do the dynamic remuxing of pins.
So omap3 can use:
mmc: mmc@4800abcd {
compatible = "ti,omap3-hsmmc";
...
interrupts-extended = <&intc 83 &omap3_pmx_core 0x11a>;
...
};
And am33xx can use:
mmc: mmc@4810abcd {
compatible = "ti,omap33xx-hsmmc";
...
interrupts-extended = <&intc 64 &gpio3 28>;
...
};
Then the logic of enabling the dynamic remuxing can be done based
on the ti,omap33xx-hsmmc compatible flag if there are two interrupts
and the needed pin states are defined.

We should just add the two interrupts to the host, not to the pdata.
