Problem specifying which gpio_126 to use on omap353x

On my board I have an isp1760 hooked up using gpio_126 (pin P27 -
MMC1_DAT4/SIM_IO/GPIO_126). From the schematics (and TRM), there is a
2nd gpio_126 on pin D25 (CAM_STROBE/GPIO_126).

I tried to use:

#define ISP1760_IRQ 126

omap_mux_init_gpio(ISP1760_IRQ, OMAP_PIN_INPUT_PULLUP);
if (gpio_request(ISP1760_IRQ, "isp1760 IRQ") < 0) {
printk(KERN_ERR "Failed to request GPIO%d for isp1760IRQ\n", ISP1760_IRQ);
return;
}

And in the log I see:

mux: Multiple gpio paths for gpio126
mux: Multiple gpio paths for gpio126
Failed to request GPIO126 for isp1760 IRQ

How do I tell gpio_request()and friends that I want to use GPIO_126 on
pin P27, not GPIO_126 on pin D25?

Thanks in advance!
