Don't add timing parameters in the device tree. Add the panel support
in the simple panel driver and use the drm mxsfb bindings.

Keep the node names sorted . Except iomuxc that can go as the last one.

The unit address and reg values do not match. This would trigger a dtc
warning if you build it with W=1.
Please make sure that you get no dtc warning in v2

Node names should be generic and label names should be specific, so:

There is no need for this imx6ul-evk. Just place the pinctrl nodes
outside of it.

These should go to the LED pinctrl group instead of hog.

This should go to enet2 pin group instead of hog.

Is this for Wifi? If so you could add a pwrseq entry that could take care of it.

The subject says "board", but here you add the "UL-ULL" common dtsi.
Here should be only the "SoM" specific nodes,
please look at the arch/arm/boot/dts/imx6qdl-var-dart.dtsi and
arch/arm/boot/dts/imx6q-var-dt6customboard.dts files for the
namings and separations between the SoM and Board DTs.
Especially, all HW on the "SoM" must go in the SoM dtsi and
the hardware on the Variscite provided "Board" in the board dts.
For example, the display must be in the board, you could have some
board based on this SoM without a display for example.
WiFi/BT should go in the SoM, Ethernet in the SoM, but the ethernet
PHY in the board, because another board could use a different PHY.
For audio, the codec should go in the SoM, but the audio card node
should go in the board, since the routing is board specific because
the board could have some other HW behind like amplifier, ...
Finally, the "board" should be named "6ulcustomboard" because it's
the actual board name used by variscite :
