i.MX8QXP LPSPI device

I'm trying to access the lpspi channels on my i.MX8QXP.  From the baseboard schematics, I found where LPSPI0 connects to the Arduino/MikroBus connector.  I have this wired to a spi slave device (an STM32H743ZI development board from ST Micro).  My question is how to get our (Yocto) Linux to recognize the spi device and enumerate it as /dev/spidev0.0 (or something like that).  Once I can actually access the device, I should be able to test with it...


Thanks in advance,
