Just to make sure: this patch should be already under FreeBSD 12.1 =
release ? Correct ?=20

I see correctly the device:

% dmesg | grep nxp
nxprtc0: <NXP PCF2129 RTC> at addr 0xa2 on iicbus0
nxprtc0: registered as a time-of-day clock, resolution 0.015625s


% sysctl -b hw.fdt.dtb | dtc -I dtb -O dts | grep pcf
			pcf2129@51 {
				compatible =3D "nxp,pcf2129";

Thanks,
