Ok, I assume that arch/arm/mach-mx28/mx28evk_pins.orig.c is the
original imx28-evk pinmux
and arch/arm/mach-mx28/mx28evk_pins.c contains the specific pinmux for
the imx28-wink-hub-v1 board.

The first thing I noticed is that the duart pins are different between
the two boards.

imx28-wink-hub-v1 uses the I2C0 pads for duart.

Can you try the attached two patches that I generated against 6.1.34?

It is a super minimal device tree for imx28-wink-hub-v1 and should
allow you to boot until it searches for the rootfs.

I am glad you managed to start seeing kernel console using a mainline kernel :-)
