drm/amd/pm: implement processor fine grain feature for vangogh (v3)
This patch is to implement the processor fine grain feature for vangogh.
It's similar with gfx clock, the only difference is below:
echo "p core_id level value" > pp_od_clk_voltage
1. "p" - set the cclk (processor) frequency
2. "core_id" - 0/1/2/3, represents which cpu core you want to select
2. "level" - 0 or 1, "0" represents the min value, "1" represents the
max value
3. "value" - the target value of cclk frequency, it should be limited in
the safe range
v2: fix some missing changes as Evan's suggestion.
v3: add version check and fix the restore.
