[PATCH 0/5] 0 MHz is not a valid current frequency

[Luben Tuikov]

Some ASIC support low-power functionality for the whole ASIC or just
an IP block. When in such low-power mode, some sysfs interfaces would
report a frequency of 0, e.g.,

$cat /sys/class/drm/card0/device/pp_dpm_sclk
0: 500Mhz 
1: 0Mhz *
2: 2200Mhz 
$_

An operating frequency of 0 MHz doesn't make sense, and this interface
is designed to report only operating clock frequencies, i.e. non-zero,
and possibly the current one.

When in this low-power state, round to the smallest
operating frequency, for this interface, as follows,

$cat /sys/class/drm/card0/device/pp_dpm_sclk
0: 500Mhz *
1: 2200Mhz 
$_

Luben Tuikov (5):
  drm/amd/pm: Slight function rename
  drm/amd/pm: Rename cur_value to curr_value
  drm/amd/pm: Rename freq_values --> freq_value
  dpm/amd/pm: Sienna: 0 MHz is not a current clock frequency
  dpm/amd/pm: Navi10: 0 MHz is not a current clock frequency
