You are using the deprecated bindings.

Please switch to the DRM bindings as stated at
Documentation/devicetree/bindings/display/mxsfb.txt

You should also add your panel to the simple panel driver.

That would be the best solution :)

The status line can be dropped.

Where is the phandle?

Also this phandle.. I saw this a few times within this dts. Please make
sure that your dts(i) files are self-contained so move the muxing to
this dts. This happens a few time, I don't list all phandles.

Do you need the cpu_dai phandle?

This is the only place where you use this regulator so can we move the
regulator to this dts instead of the common dtsi?

Can this go to the common dtsi file?

ok thx for you comments, coming back to this. I now added this to
panel-simple.c. Is this the way to go?
