Hi all,

In the schematic of imx6-sabresd reference board. I found 2 pins (ENET_TX_EN and ENET_RXD1) but i cannot find how these pins are mapped in device tree (file imx6qdl-sabresd.dtsi). My question is: "Are these pins used by driver? If yes, please show me how to map these pin in device tree".

Here is pin map for enet that is available in device tree for imx6-sabresd.

Hi Thinh

if these signals can not be found in dts, seems they are not used in particular bsp.

In general this depends on used bsp, as different vendors improve or add additional bsp capabilities

FSL Community BSP Release Notes 2.2 documentation 

For example on below case ENET_TX_EN was used as wake on lan
