Improve pp_od_clk_voltage OD_RANGE for RX 6800 XT
Right now /sys/class/hwmon/hwmon3/subsystem/hwmon4/device/pp_od_clk_voltage only contains minimum and maximum values (OD_RANGE) for core and memory frequencies on my RX 6800 XT. Kernel 5.12
Wouldn't it be useful to add the voltate range here as well? I can't seem to volt my card below 868 mV, would be nice to know if this is the actual limit.
