ECSPI2 on i.MX8M Mini EVK

I see that the ECSPI2 pins are brought out on J1003 on the imx8mmevk board, but I can't seem to make SPI work. I try running the ECSPI unit test, but it fails suggesting the device isn't present. Can someone please provide direction on what needs to be done (modify the device tree maybe?) and how to do it using yocto on top of the fsl-validation-image-imx image?
