c66c670ded drm/i915/psr: Split intel_psr2_config_valid for panel replay 
Part of intel_psr2_config_valid is valid for panel replay. rename it as
intel_sel_update_config_valid. Split psr2 specific part and name it as
intel_psr2_config_valid.

v3:
  - move early transport check to psr2 specific check
  - check intel_psr2_config_valid only for non-Panel Replay case
v2:
  - use psr2_global_enabled for panel replay as well
  - goto unsupported instead of return when global enabled check fails

d210d8c0df drm/i915/psr: Modify intel_dp_get_su_granularity to support panel replay 
Currently intel_dp_get_su_granularity doesn't support panel replay.
This fix modifies it to support panel replay as well.

v4:
  - use drm_dp_dpcd_readb instead of drm_dp_dpcd_read
  - ensure return value is 0 if drm_dp_dpcd_readb fails
v3: use correct offset for DP_PANEL_PANEL_REPLAY_CAPABILITY

1d81ee5562 drm/i915/psr: Calculate IO wake and fast wake lines for DISPLAY_VER < 12 
Bspec mentions 50 us for IO wake time and 32 us for fast wake time. 32 us
is most probably wrong as it doesn't meet the specification as fast wake
time is calculated in Bspec like this:

10..16 us (precharge) + 8 us (preamble) + 4 us (phy_wake) + 20 us
(tfw_exit_latency)

Instead of using these constants calculate IO wake and fast wake for
DISPLAY_VER < 12 as well.

v3:
  - do not handle < 9 separately
  - add own helper for skl and tgl io buffer wake times
v2:
  - initialize io/fast_wake_time for display version < 9

fe10e7c681 drm/i915/psr: Improve fast and IO wake lines calculation 
Current fast and IO wake lines calculation is assuming fast wake sync
length is 18 pulses. Let's improve this by checking actual length.

Add getter for IO buffer wake time and return 10 us there which was assumed
with static 42 us IO wake time. Upcoming patches will extent this for
different display versions.

Bspec: 65450

v3:
  - s/get_io_buffer_wake_time/io_buffer_wake_time/ and use it directly in
    calculation.
v2:
  - rename io_wake_time in if block to io_buffer_wake_time
  - rename get_io_wake_time to get_io_buffer_wake_time
