* Xe's Freq provides a sysfs API for frequency management:
*
* device/tile#/gt#/freq0/<item>_freq *read-only* files:
*
* - act_freq: The actual resolved frequency decided by PCODE.
* - cur_freq: The current one requested by GuC PC to the PCODE.
* - rpn_freq: The Render Performance (RP) N level, which is the minimal one.
* - rpa_freq: The Render Performance (RP) A level, which is the achiveable one.
* Calculated by PCODE at runtime based on multiple running conditions
* - rpe_freq: The Render Performance (RP) E level, which is the efficient one.
* Calculated by PCODE at runtime based on multiple running conditions
* - rp0_freq: The Render Performance (RP) 0 level, which is the maximum one.
*
* device/tile#/gt#/freq0/<item>_freq *read-write* files:
*
* - min_freq: Min frequency request.
* - max_freq: Max frequency request.
* If max <= min, then freq_min becomes a fixed frequency request.
