b1d43e6fb3 drm/i915/dp: Flush modeset commits during connector detection 
Make sure that a DP connector detection doesn't happen in parallel
with an ongoing modeset on the connector. The reasons for this are:

- Besides reading the capabilities, EDID etc. the detection may change
  the state of the sink (via the AUX bus), for instance by setting the
  LTTPR mode or the source OUI (the latter introduced by an upcoming
  patch). It's better to avoid such changes affecting an onging modeset
  in any way.

- During a modeset's link training any access to DPCD registers, besides
  the registers used for link training should be avoided, at least in
  the LTTPR non-transparent and transparent link training modes.

  Such asynchronous accesses - besides connector detection - can also
  happen via the AUX device node for instance, for those a parallel
  modeset will have to be avoided in a similar way to the change in this
  patch. (A topic for a follow-up change.)

- The source OUI written to an eDP sink is valid only while the panel
  power is enabled. A modeset on eDP will enable/disable the panel power
  synchronously; this should be prevented in the middle of the connector
  detection, to ensure a consistent sink state (which depends on the
  source OUI) for the whole duration of detection. The panel power could
  still get disabled during detection after an idle period (1 sec), this
  will be prevented by the next patch.

- Get drm_device using an intel_display instead of drm_i915_private ptr.

5eb2e78559 drm/i915/display: use x100 version for full version and release 
Use x100, or ver * 100 + rel, versions for full IP version checks,
similar to what xe driver does:

- Replace IP_VER(14, 1) inline with 1401, etc.

- Convert DISPLAY_VER_FULL() to DISPLAY_VERx100()

- Convert IS_DISPLAY_VER_FULL() to IS_DISPLAY_VERx100()

- Convert IS_DISPLAY_VER_STEP() to IS_DISPLAY_VERx100_STEP()

This makes ver.rel versions easier to use, follows the xe driver
pattern, and drops the dependency on the IP_VER() macro.

v2: Rebase, drop IP_VER() from xe compat headers

v3: Rebase

96670b2b0f drm/i915/display: add subplatform group for HSW/BDW ULT 
Add support for defining aliases for subplatform groups, such as HSW/BDW
ULT that covers both ULT and ULX.

ULT is a special case, because we slightly abuse the ULT subplatform
both as a subplatform and group, but with the way this is defined, it
should be fairly clear.

This follows i915 core and IS_HASWELL_ULT()/IS_BROADWELL_ULT()
conventions, i.e. "is ULT" also matches ULX platforms.

Note: Pedantically, this should have been done earlier, but it's only
feasible now that we no longer have a subplatform enum and can actually
initialize multiple subplatforms.

v2: Use the subplatform group idea

ae03d70748 drm/i915/xe3lpd: Update pmdemand programming 
There are some minor changes to pmdemand handling on Xe3:
 - Active scalers are no longer tracked.  We can simply skip the readout
   and programming of this field.
 - Active dbuf slices are no longer tracked.  We should skip the readout
   and programming of this field and also make sure that it stays 0 in
   our software bookkeeping so that we won't erroneously return true
   from intel_pmdemand_needs_update() due to mismatches.
 - Even though there aren't enough pipes to utilize them, the size of
   the 'active pipes' field has expanded to four bits, taking over the
   register bits previously used for dbuf slices.  Since the lower bits
   of the mask have moved, we need to update our reads/writes to handle
   this properly.

v2: active pipes is no longer always max 3, add in the ability to go to
4 for PTL.
v3: use intel_display for display_ver check, use INTEL_NUM_PIPES
v4: add a conditional for number of pipes macro vs using 3.
v5: reverse conditional order of v4.
v6: undo v5 and fix num_pipes assignment
v7: pass display struct instead of i915, checkpatch fix
v8: Alignment issue
