You could remove bootargs and let the bootloader pass it.
We usually don't pass bootargs in the i.MX dts files.

otherwise you will get dtc build warnings with W=1.

No need for this 'regulators' container.

Remove the reg = <0>
Same applies to other regulators.

Why passing 'enable-active-high' when this is not gpio controlled?

You should add xea to the vendor prefix in a separate patch.
You also need to add thie board to
Documentation/devicetree/bindings/arm/fsl.yaml

You can drop this one.

You could remove bootargs and let the bootloader pass it.
We usually don't pass bootargs in the i.MX dts files.

otherwise you will get dtc build warnings with W=1.

No need for this 'regulators' container.

Remove the reg = <0>
Same applies to other regulators.

Why passing 'enable-active-high' when this is not gpio controlled?

Same here.

Node names should be generic
flash@0

compatible = "xea,imx20-lwe", "fsl,imx28";
You should add xea to the vendor prefix in a separate patch.
You also need to add thie board to
Documentation/devicetree/bindings/arm/fsl.yaml
