Currently ALPM LFPS and silence period are hardcoded for different
link rates. This patch set implements calculation for these
parameters.

Also AUXLess wake time is optimized by using actual LFPS cycles and
silence period instead of maximum values.

v2: replace hardcoded 20 with 2 * LFPS_CYCLE_COUNT

Jouni Högander (4):
  drm/i915/alpm: Calculate silence period
  drm/i915/alpm: Add own define for LFPS count
  drm/i915/alpm: Replace hardcoded LFPS cycle with proper calculation
  drm/i915/alpm: Use actual lfps cycle and silence periods in wake time
