You can look at
"36.4.316 Pad Control Register
(IOMUXC_SW_PAD_CTL_PAD_ENET_TX_DATA1)" in the mx6quad reference manual.

For GPIO functionality the default power-on-reset value should work fine.

You can confirm this by reading address 0x20E0500 in the bootloader:
mw.l 0x20E0500 1

and then use this value on the dts. This way the kernel will always
have a sane value instead of relying in the value passed from the
bootloader.
