imx7d fec0 interrupt pin - how to define/check

Hi, I'm using UART3_RXD for the fec0 interrupt on the imx7d and cannot find any specific reference to this pin in the device tree. Googling MX7D_PAD_UART3_RX_DATA__ENET1_1588_EVENT0_IN ( being my pad ) nothing turns up which gives me the impression I'm missing something. 

 

There are a few interrupts defined in the dtsi, but I have no idea how these relate to pads.

interrupts = <GIC_SPI 118 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 119 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 120 IRQ_TYPE_LEVEL_HIGH>; 

 

Any help would be appreciated, a simple explanation instead of linking a pdf would be appreciated!
