newbie: phy platform interrupt config

Hi

I would like to set the interrupt for the phy on the i.mx35 pcm43 in the file 
arch/arm/mach-imx/mach-pcm043.c. Unfortunatly i didn't find a way to specify 
it. So i want to set the field (struct phy_device*)->irq.

What i managed so far is to request the gpio for the interrupt:
#define IMX_PHY_IRQ IMX_GPIO_NR(2,7)
gpio_request(IMX_PHY_IRQ, "FEC PHY irq");
gpio_direction_input(IMX_PHY_IRQ);

Now i guess the result of "gpio_to_irq(IMX_PHY_IRQ)" should go into some kind 
of argument to imx35_add_fec(pdata) which is a macro 
imx_add_fec(&imx35_fec_data, pdata).
pdata is of type (?) struct fec_platform_data which contains phy_interface_t 
and unsigned char array. So i don't see a way to set the phy interrupt there.

I tried search for a driver which set the phy irq but i didn't find any and 
setting the phy in the phy_fixup function is also not working since the 
interrupt seems not get registered when opening the device.

So how do i set the phy interrupt line in the platform file?

Best regards
Tim

The cc list is from scripts/get_maintainer.pl -f drivers/net/phy/ which are 
hopefully the right maintainers plus Andy Fleming which commited the 
documentation for libphy.
