GPIO IRQ triggering continually?

[conradmenchine]

Hi,
I have an interrupt set up for a SPI device that looks like this in the device tree:

spi@0{
        ...
	interrupt-parent = <&tegra_main_gpio>;
	interrupts = <TEGRA234_MAIN_GPIO(G, 03) IRQ_TYPE_LEVEL_LOW>;
}

For some reason, the irq is triggering continuously even with the pin tied high. I have verified that the signal is getting into the SOM by using /sys/class/gpio to read that exact pin and checked that high and low pin states are working. If I change it to edge-triggered, it never triggers. It's almost as if the kernel is reading the GPIO as low all the time, regardless of the real state. Has anyone seen this?
Thanks
