</span>Can you try to use the existing<br>
arch/arm/boot/dts/imx6qdl-<wbr>wandboard.dtsi instead?<br>
<br>
I don't have access to a imx6qp wandboard and don't know the hardware<br>
changes that would justify a different dtsi.<br>
<br>
Anyway, I would start with the existing dtsi in mainline and then make<br>
the adjustments inside the imx6qp-wandboard.dts if needed.<br>
<br>
It would also be nice if you could submit the dts changes upstream.<br>
