How to powerd in FREEBSD 12.1 STABLE over RPI-B

[Miguel]

Hi all, I hope you can help me with this

I have used powerd since FREEBSD 10.2 on my RPI-B, but when
upgrading to FREEBSD 12 I can't get it to work. If i run:
	powerd
	powerd: no cpufreq (4) support - aborting: No such file or
	directory

it seems that this feature is not enabled by default
I also can't find any CPU when running

dmesg | grep cpu
(show nothing)

however if I run these same commands under FreeBSD 11.2 I get
different results:

	dmesg | grep cpu

cpulist0: <Open Firmware CPU Group> on ofwbus0
cpu0: <Open Firmware CPU> on cpulist0
bcm2835_cpufreq0: <CPU Frequency Control> on cpu0
bcm2835_cpufreq0: ARM 700MHz, Core 250MHz, SDRAM 400MHz, Turbo OFF 


  and the powerd daemon works

powerd
	powerd: powerd already running, pid: 789

Maybe something missing in dts?

regards,

Miguel
