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>;
...
};
Hi Tony,
I made similar changes for omap4 panda-es as below, but get WARNING for no irq
domain [1]
omap3 beagle seems to be OK.
mmc1: mmc@4809c000 {
compatible = "ti,omap4-hsmmc";
reg = <0x4809c000 0x400>;
+ interrupts-extended = <&gic GIC_SPI 83 IRQ_TYPE_LEVEL_HIGH
&omap4_pmx_core 0xa8>;
ti,hwmods = "mmc1";
