It appears to be a very old driver with no support for FDT data. But it's the only thing that exists right now for freebsd. https://socsvn.freebsd.org/socsvn/soc2015/mihai/bhyve-on-arm-head/sys/arm/lpc/lpc_spi.c It might be worth checking whether netbsd or openbsd has a driver, those can often be ported to freebsd without much trouble. -- Ian > > On Fri, May 1, 2020 at 1:59 PM Kamal R.
