The diff below exposes voltage regulators as sensors. This makes it easy to look at the current settings of these regulators. The downside is that these aren't really sensors as the voltages are not actually measured. The functionality is optional; callers can pass NULL in the regulator_register() if the regulators aren't particularly interesting. This is what it looks like on the rk3399-firefly: milhaud$ sysctl hw.sensors hw.sensors.rktemp0.temp0=23.89 degC (CPU) hw.sensors.rktemp0.temp1=28.75 degC (GPU) hw.sensors.rkpmic0.volt0=0.90 VDC (vdd_cpu_l) hw.sensors.rkpmic0.volt1=1.80 VDC (vcc1v8_dvp) hw.sensors.rkpmic0.volt2=1.80 VDC (vcc1v8_pmu) hw.sensors.rkpmic0.volt3=3.00 VDC (vcc_sd) hw.sensors.rkpmic0.volt4=1.80 VDC (vcca1v8_codec) hw.sensors.rkpmic0.volt5=3.00 VDC (vcc_3v0) thoughts?
As someone who does hardware stuff, having easy access to these sensorts can't hurt, and might be useful in some situations. I've measured voltages before and found during extreme temperature conditions things changed. So it's possibly useful and doesn't cost much.
