[Intel-gfx] [PATCH v4 1/6] drm/i915/dp: Some reshuffling in mode_valid as prep for bigjoiner modes

[Manasi Navare]

No functional changes. This patch just moves some mode checks
around to prepare for adding bigjoiner related mode validation

[Intel-gfx] [PATCH v4 2/6] drm/i915: Move encoder->get_config to a new function

[Manasi Navare]

No functional changes, create a separate intel_encoder_get_config()
function that calls encoder->get_config hook.
This is needed so that later we can add beigjoienr related
readout here.

[Intel-gfx] [PATCH v4 3/6] drm/i915: Add hw.pipe_mode to allow bigjoiner pipe/transcoder split

[Manasi Navare]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

With bigjoiner, there will be 2 pipes driving 2 halves of 1 transcoder,
because of this, we need a pipe_mode for various calculations, including
for example watermarks, plane clipping, etc.

v8:
* Add pipe_mode in readout in verify_crtc_state (Ville)
v7:
* Remove redundant comment (Ville)
* Just keep mode instead of pipe_mode (Ville)
v6:
* renaming in separate function, only pipe_mode here (Ville)
* Add description (Maarten)
v5:
* Rebase (Manasi)
v4:
* Manual rebase (Manasi)
v3:
* Change state to crtc_state, fix rebase err  (Manasi)
v2:
* Manual Rebase (Manasi)

[Intel-gfx] [PATCH v4 4/6] drm/i915: Pass intel_atomic_state instead of drm_atomic_state

[Manasi Navare]

No functional changes, to align with previous cleanups pass
intel_atomic_state instead of drm_atomic_state.
Also pass this intel_atomic_state with crtc_state to
some of the atomic_check functions.

[Intel-gfx] [PATCH v4 5/6] drm/i915/dp: Prep for bigjoiner atomic check

[Manasi Navare]

No functional changes here. Just pass intel_atomic_state
along with crtc_state to certain atomic_check functions.
This will lay the foundation for adding bigjoiner master/slave
states in atomic check.

v2:
* More prep with intel_atomic_state (Ville)

[Intel-gfx] [PATCH v4 6/6] drm/i915/dp: Allow big joiner modes in intel_dp_mode_valid(), v3.

[Manasi Navare]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

Small changes to intel_dp_mode_valid(), allow listing modes that
can only be supported in the bigjoiner configuration, which is
not supported yet.

v12:
* slice_count logic simplify (Ville)
* Fix unnecessary changes in downstream_mode_valid (Ville)
v11:
* Make intel_dp_can_bigjoiner non static
so it can be used in intel_display (Manasi)
v10:
* Simplify logic (Ville)
* Allow bigjoiner on edp (Ville)
v9:
* Restric Bigjoiner on PORT A (Ville)
v8:
* use source dotclock for max dotclock (Manasi)
v7:
* Add can_bigjoiner() helper (Ville)
* Pass bigjoiner to plane_size validation (Ville)
v6:
* Rebase after dp_downstream mode valid changes (Manasi)
v5:
* Increase max plane width to support 8K with bigjoiner (Maarten)
v4:
* Rebase (Manasi)

Changes since v1:
- Disallow bigjoiner on eDP.
Changes since v2:
- Rename intel_dp_downstream_max_dotclock to intel_dp_max_dotclock,
  and split off the downstream and source checking to its own function.
  (Ville)
v3:
* Rebase (Manasi)
