Since the beginning there is a missunderstanding on the meaning of this
dpcd bit.
This bit shouldn't indicate whether to use link standby or not, but just
be used to configure TP1, TP2 and TP3 times and tell hw aux should be skiped
since HW is the responsible one.
Even with help of frontbuffer tracking, HW is still fully responsible for
PSR exit logic with/without DP training.
DP_PSR_NO_TRAIN_ON_EXIT means the source doesn't need to do the training, but
it doesn't tell to avoid TP patterns, so we will send minimal TP1 and avoid
TP2. It also means that sink itself can take up to 5 idle frames for training.
6 in our case since we might be off by 1. So we also increment idle_frames by 4
here.
v2: Fix and improve commit message (Durga).
v3: Use minimal TP1 time avoiding TP2 and increase idle frame.

This wrong logic and useless define came from first versions and
came along with all rework. Just now I notice how ugly, wrong and
useless this is.
val is already defined as 0 anyway and logic is completelly wrong
and useless. So let's starting the link_standby fix with this
cleaning.

GMBUS interrupt has been moved to CPU side in BXT.
What this patch does is:
1. Enable GMBUS IRQ in de_post_install function
2. Handle this interrupt as a port interrupt in display irq
handler
v2: Rebase on top of the for_each_pipe() change adding dev_priv as
first argument (Damien).
v3: read BXT_DE_PORT_GMBUS IIR flag only on BXT on other platforms
it's reserved (imre)
v4: (jani)
- remove redundant 'BXT GMBUS' comment
- fix formatting of BXT_DE_PORT_GMBUS definition

This patch adds conditional checks in gen8_irq functions
to support BXT. Most of the checks just look for PCH split
availability, and block the call to PCH interrupt functions if
not available.
v2: (jani)
- drop redundant TODO comment about PCH IRQ flags on BXT
- check HAS_PCH_SPLIT instead of IS_BROXTON when handling PCH specific
IRQ events in gen8_irq_handler()
- check HAS_PCH_SPLIT before calling the function instead of a
corresponding early return within the called function for
ibx_irq_reset(), ibx_irq_pre_postinstall(), ibx_irq_postinstall()
v3: (jani)
- in ironlake_irq_postinstall() and ironlake_irq_reset() HAS_PCH_SPLIT
is always true, so drop the check for it

This patch adds a hot plug interrupt handler function for BXT.
What this function typically does is:
1. Check if hot plug is enabled from hot plug control register.
2. Call hpd_irq_handler with appropriate trigger to detect a
plug storm and schedule a bottom half.
3. Clear sticky status bits in hot plug control register..
v2: (jani)
- drop redundant unlikely()
- s/Todo/FIXME:/ in code comment
- declare 'found' var in the scope where it's used
- check for IS_BROXTON before handling BXT_DE_PORT_HOTPLUG_MASK

In BXT, DDI hotplug control has been moved to CPU from PCH.
This patch adds a new IRQ setup function for BXT which:
1. Checks which HPD ports are requested to be enabled by encoders.
2. Enables those ports in the hot plug control register.
3. Un-masks these port interrupts in the IMR register.
4. Enables these port interrupts in the IER register.
V3: Kept the default HPD filter count to default (500 us) as per
satheesh's comment
v4: Remove unused HPD filter defines (Damien)
v5: warn if trying to setup HPD on port A (imre)
v6: fix order of definitions for register bitfields (Daniel)
v7: (jani)
- define the size of the hpd_bxt array explicitly for bound checking
- use for_each_intel_encoder instead of open coding it
- fix format/order of definitions for BXT_HOTPLUG_CTL reg bitfields

For BXT gmbus is pulled from PCH to CPU. From implementation point of
view only pin pair configuration will change. The existing
implementation supports all platforms previous to GEN8 and also SKL. But
for BXT pin pair configuration is completely different than SKL or other
previous GEN's. This patch introduces the new pin pair configuration
structure specific to BXT and also ensures every real gmbus port has a
gpio pin.
v3 by Jani: with the platform independent prep work in place, the bxt
enabling reduces to a fairly trivial patch. Credits are due Sunil for
giving me the ideas (with his patches) what the platform independent
parts should look like.
v4: Fix intel_hdmi_init_connector() for bxt. Abstract gmbus_pin access
more. s/GPU/PCH/ in commit message.
v5: Rebase.

For BXT, DDI buf idle timeout delay needs to be increased to 16us.
Since this is a timeout value and we return as soon as the condition is
realized, no penalty incurred for other platforms.
v2:
- remove TIMEOUT macro used only at a single place (Daniel)

This provides a nice boost to mesa in swap bound scenarios (as mesa
throttles itself to the previous frame and given the scenario that will
complete shortly). It will also provide a good boost to systems running
with semaphores disabled and so frequently waiting on the GPU as it
switches rings. In the most favourable of microbenchmarks, this can
increase performance by around 15% - though in practice improvements
will be marginal and rarely noticeable.
v2: Account for user timeouts
v3: Limit the spinning to a single jiffie (~1us) at most. On an
otherwise idle system, there is no scheduler contention and so without a
limit we would spin until the GPU is ready.
v4: Drop forcewake - the lazy coherent access doesn't require it, and we
have no reason to believe that the forcewake itself improves seqno
coherency - it only adds delay.

Added intel_atomic_setup_scalers to setup scalers based on
staged scaling requests from a crtc and its planes. If staged
requests are supportable, this function assigns scalers to
requested planes and crtc. Note that the scaler assignement
itself is staged into crtc_state and respective plane_states
for later commit after all checks have been done.
overall high level flow:
- scaler requests are staged into crtc_state by planes/crtc
- check whether staged scaling requests can be supported
- add planes using scalers that aren't in current transaction
- assign scalers to requested users
- as part of plane commit, scalers will be committed
(i.e., either attached or detached) to respective planes in hw
- as part of crtc_commit, scaler will be either attached or detached
to crtc in hw
crtc_compute_config calls intel_atomic_setup_scalers() to start
scaler assignments as per scaler state in crtc config. This call
should be moved to atomic crtc once it is available.
v2:
-removed a log message (me)
-changed input parameter to crtc_state (me)

skylake scaler structure definitions. scalers live in crtc_state as
they are pipe resources. They can be used either as plane scaler or
panel fitter.
scaler assigned to either plane (for plane scaling) or crtc (for panel
fitting) is saved in scaler_id in plane_state or crtc_state respectively.
scaler_id is used instead of scaler pointer in plane or crtc state
to avoid updating scaler pointer everytime a new crtc_state is created.
v2:
-made single copy of min/max values for scalers (Matt)
v3:
-updated commentary for scaler_id (me)
v4:
-converted src/dst ranges to #defines, dropped ratios (Matt)

When RC6 along with Render power gating is enabled, GPU hang
happens due to lack of synchronization between GTI and Render
power gating.

Connector states were being allocated in intel_setup_outputs() in loop
over all connectors. That meant hot-added connectors would have a NULL
state. Since the change to use a struct drm_atomic_state for the legacy
modeset, connector states are necessary for the i915 driver to function
properly, so that would lead to oopses.
v2: Fix test for intel_connector_init() success in lvds and sdvo (PRTS)
