There are some changes in LunarLake IO and Fast Wake configuration:

IO Wake Lines configuration is now 6 bits wide
Fast Wake Lines configuration is now 6 bits wide and in ALPM_CTL register
PSR2_CTL[Block count number] is not valid for LunarLake and onwards

This patch set modifies the driver accordingly.

v2: maximum line count is 68 (6 bits + 5 lines added by HW)

Jouni Högander (3):
  drm/i915/psr: LunarLake IO and Fast Wake time line count maximums are
    68
  drm/i915/psr: LunarLake PSR2_CTL[IO Wake Lines] is 6 bits wide
  drm/i915/psr: PSR2_CTL[Block Count Number] not needed for LunarLake
