How to control ECSPI2 on i.MX8M Mini EVK

I want to use the ECSPI2 interface (available on J1003) on a i.MX8M Mini EVK to send data to a D/A chip and to receive data from an A/D chip. I am running a yocto 4.19.35 linux build, although I could shift to a different release if necessary.

 

Can someone point me to information that would allow me to exercise the ECSPI2 interface from a C program, ideally in user space? Any associated command line tools would also be welcome.

 

Thank you,

Eric
