Looks like cut/paste error from the other device cfgs (which do support

If the bottom-most layer is not fullscreen, we need to use the BASE
mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT). The
blend_setup() code pretty much handled this already, we just had to
figure this out in _atomic_check() and assign the stages appropriately.
Also fix the case where there are zero enabled planes, where we also
need to enable BORDER_OUT.

send_mutex is used to serialise communication with GuC via
intel_guc_send().
Since functions that utilize it are no longer limited to submission,
initialization should be handled as a part of general setup.

guc_send(), guc_recv() and related functions were introduced in the
i915_guc_submission.c and their scope was limited only to that file.
Those are not submission specific though.
This patch moves moves them to intel_uc.c with intel_ prefix added.

To facilitate code reorganization we are renaming everything that
contains guc2host or host2guc.
host2guc_action() and host2guc_action_response() become guc_send()
and guc_recv() respectively.
Other host2guc_*() functions become simply guc_*().
Other entities are renamed basing on context they appear in:
- HOST2GUC_ACTIONS_& become INTEL_GUC_ACTION_*
- HOST2GUC_{INTERRUPT,TRIGGER} become GUC_SEND_{INTERRUPT,TRIGGER}
- GUC2HOST_STATUS_* become INTEL_GUC_STATUS_*
- GUC2HOST_MSG_* become INTEL_GUC_RECV_MSG_*
- action_lock becomes send_mutex
v2: drop unnecessary backslashes and use BIT() instead of '<<'
v3: shortened enum names and INTEL_GUC_STATUS_*

If hdlcd_drm_bind() fails at drm_fbdev_cma_init(), its cleanup will call
drm_mode_config_cleanup() as if to balance drm_mode_config_reset(). The
net result is that drm_connector_cleanup() will clean up the active
connectors long before component_unbind_all() gets called, so when the
connector later tries to clean up itself after being unbound, Bad Things
can happen:

The check in __intel_uncore_early_sanitize() to disable decoupled mmio
would disable it for every platform that is not broxton. While that's
not a problem now since only broxton supports that, simply setting
.has_decoupled_mmio in a new platform's device info wouldn't suffice. So
avoid future confusion and change the workaround to only change the
value of has_decoupled_mmio for broxton.
v2: git add compile fix. (Ander)

Pass dev_priv to intel_setup_outputs() and functions called by it, since
those are all intel i915 specific functions. Also, in the majority of
the functions dev_priv is used more often than dev. In the rare cases
where there are a few calls back into drm core, a local dev variable was
added.
v2: Don't convert dev to &dev_priv->drm in intel_dsi_init. (Ville)

* improve the compliance for sending infoframes and audio
* re-organise the function order in the driver to group like functions

The i915_next_seqno read value is to be the next seqno used by the
kernel. However, in the conversion to atomics ops for gt.next_seqno, in
commit 28176ef4cfa5 ("drm/i915: Reserve space in the global seqno during
request allocation"), this was changed from a post-increment to a
pre-increment. This increment was missed from the value reported by
debugfs, so in effect it was reporting the current seqno (last
assigned), not the next seqno.

i915_hws_info() has not been kept upto date (missing new engines) and so
I consider it to be unused. HWS is included in the error state, which
would be an avenue to retrieving it if required in future (possibly via
i915_engine_info). As it is currently oopsing with an rpm testcase, just
remove it.

Current dw-hdmi is supporting sound via AHB bus, but it has
I2S audio feature too. This patch adds I2S audio support to dw-hdmi.
This HDMI I2S is supported by using ALSA SoC common HDMI encoder

inserting a node into this hole requires any additional space, and so if

The probe function requests the interrupt before initializing
the ddp component. Which leads to a null pointer dereference at boot.
Fix this by requesting the interrput after all components got
initialized properly.

Tune dsi frame rate by pixel clock, dsi add some extra signal (i.e.
Tlpx, Ths-prepare, Ths-zero, Ths-trail,Ths-exit) when enter and exit LP
mode, those signals will cause h-time larger than normal and reduce FPS.
So need to multiply a coefficient to offset the extra signal's effect.
coefficient = ((htotal*bpp/lane_number)+Tlpx+Ths_prep+Ths_zero+
Ths_trail+Ths_exit)/(htotal*bpp/lane_number)

For 64bit bar while reading the higher 32bit the value should be returned

In the current implementation the higher 32bit value was discarded and not
written to the cfg space of vgpu which lead to an incorrect bar size.

A modeset on one pipe can update dev_priv->atomic_cdclk_freq without
actually touching the hardware, in which case we won't force a modeset
on all the pipes, and thus won't lock any of the other pipes either.
That means a parallel plane update on another pipe could be looking at
a stale dev_priv->atomic_cdcdlk_freq and thus fail to notice when the
plane configuration is invalid, or potentially reject a valid update.
To overcome this we must protect writes to atomic_cdclk_freq with
all the crtc locks, and thus for reads any single crtc lock will
be sufficient protection.

When we end up not recomputing the cdclk, we need to populate
intel_state->cdclk with the "atomic_cdclk_freq" instead of the
current cdclk_freq. When no pipes are active, the actual cdclk_freq
may be lower than what the configuration of the planes and
pipes would require from the point of view of the software state.
This fixes bogus WARNS from skl_max_scale() which is trying to check
the plane software state against the cdclk frequency. So any time
it got called during DPMS off for instance, we might have tripped
the warn if the current mode would have required a higher than
minimum cdclk.
