 * 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.
