drm/imx: i.MX5 regression fix and i.MX6QP PRE/PRG stability fixes
- Disable channel burst locking on IPUv3EX (i.MX51) and IPUv3M (i.MX53).
This fixes a regression introduced by commit 790cb4c7c954 ("drm/imx: lock
scanout transfers for consecutive bursts").
- Give PRG a head start. Waiting for both double buffers to fill up before
enabling the IPU improves startup reliability.
- Avoid PRE control register updates during unsafe window, workaround for
ERR009624.

While converting mdp5_enable/disable() calls to pm_runtime_get/put() API,
an extra call to pm_runtime_put_autosuspend() crept in
mdp5_crtc_cursor_set(). This results in calling the suspend handler
twice, and therefore clk_disables twice, which isn't a nice thing to do.

The DSI runtime PM suspend/resume callbacks check whether
msm_host->cfg_hnd is non-NULL before trying to enable the bus clocks.
This is done to accommodate early calls to these functions that may
happen before the bus clocks are even initialized.
Calling pm_runtime_put_autosuspend() in dsi_host_init() can result in
racy behaviour since msm_host->cfg_hnd is set very soon after. If the
suspend callback happens too late, we end up trying to disable clocks
that were never enabled, resulting in a bunch of WARN_ON splats.
Use pm_runtime_put_sync() so that the suspend callback is called
immediately.

While technically CHV isn't DDI, we do look at the VBT based DDI port
info for HDMI DDC pin and DP AUX channel. (We call these "alternate",
but they're really just something that aren't platform defaults.)
In commit e4ab73a13291 ("drm/i915: Respect alternate_ddc_pin for all DDI
ports") Ville writes, "IIRC there may be CHV system that might actually
need this."
I'm not sure why there couldn't be even more platforms that need this,
but start conservative, and parse the info for CHV in addition to DDI.

The PRE has a bug where a software write to the CTRL register can block
the setting of the ENABLE bit by the hardware in auto repeat mode. When
this happens the PRE will fail to handle new jobs. To work around this
software must not write to CTRL register when the PRE store engine is
inside the unsafe window, where a hardware update to the ENABLE bit
may happen.

Wait for both double buffer to be filled when first starting a channel.
This makes channel startup a lot more reliable, probably because it allows
the internal state machine to settle before the requests from the IPU are
coming in.

intel_crtc->config->cpu_transcoder isn't yet filled out when
intel_crtc_mode_get() gets called during output probing, so we should
not use it there. Instead intel_crtc_mode_get() figures out the correct
transcoder on its own, and that's what we should use.
If the BIOS boots LVDS on pipe B, intel_crtc_mode_get() would actually
end up reading the timings from pipe A instead (since PIPE_A==0),
which clearly isn't what we want.
It looks to me like this may have been broken by
commit eccb140bca67 ("drm/i915: hw state readout&check support for cpu_transcoder")
as that one removed the early initialization of cpu_transcoder from
intel_crtc_init().

crtc_state_is_legacy_gamma also checks for CTM, which was missing from
intel_color_check. By using the same condition for commit and check
we reduce the chance of mismatches.
This was spotted by KASAN while trying to rework kms_color igt test.

For this specific PCI device, the eDP panel requires a higher panel
power cycle delay of 1300ms where the minimum spec requirement of panel
power cycle delay is 500ms. This fix in combination with correct
timestamp at which we get the panel power off time fixes the dP AUX CH
timeouts seen on various IGT tests.

Kernel stores the time in jiffies at which the eDP panel is turned
off. This should be obtained after the panel is off (after the
wait_panel_off). When we next attempt to turn the panel on, we use the
difference between the timestamp at which we want to turn the panel on
and timestamp at which panel was turned off to ensure that this is equal
to panel power cycle delay and if not we wait for the remaining
time. Not waiting for the panel power cycle delay can cause the panel to
not turn on giving rise to AUX timeouts for the attempted AUX
transactions.

According to BSpec GLK like BXT needs to ignore the idle state of cores
before starting the DMC firmware's DC state handler.

The common lane power down flag of a DPIO PHY has a funky semantic:
after the initial enabling of the PHY (so from a disabled state) this
flag will be clear. It will be set only after the PHY will be used for
the first time (for instance due to enabling the corresponding pipe) and
then become unused (due to disabling the pipe). During the initial PHY
enablement we don't know which of the above phases we are in, so move
the check for the flag where this is known, the HW readout code. This is
where the rest of lane power down status checks are done anyway.
This fixes at least a problem on GLK where after module reloading, the
common lane power down flag of PHY1 is set, but the PHY is actually
powered-on and properly set up. The GRC readout code for other PHYs will
hence think that PHY1 is not powered initially and disable it after the
GRC readout. This will cause the AUX power well related to PHY1 to get
disabled in a stuck state, timing out when we try to enable it later.

drm/i915 fixes for 4.14-rc3
Couple fixes for stable:
- Fix ELD connector types and consequently audio on DP (Jani).
- Ignore HDMI on Port A and consequently fix an ops on i915 probe
when VBT advertises HDMI on Port A (Jani).
And a small fix:
- That removes a reduntant hw_check on modeset. (Colin)

The HDMI driver enables the bus and mod clocks in the bind function, but
does not disable them if it then bails our due to any errors. Neither
does it disable the clocks in the unbind function.
Fix this by adding a proper error path to the bind function, and
clk_disable_unprepare calls to the unbind function.
Also rename the err_cleanup_connector label to err_cleanup_encoder,
since it is the encoder that gets cleaned up.

drm_edid_to_eld() initializes the connector ELD to zero, overwriting the
ELD connector type initialized in intel_audio_codec_enable(). If
userspace does getconnector and thus get_modes after modeset, a
subsequent audio component i915_audio_component_get_eld() call will
receive an ELD without the connector type properly set. It's fine for
HDMI, but screws up audio for DP.
Always set the ELD connector type at intel_connector_update_modes()
based on the connector type. We can drop the connector type update from
intel_audio_codec_enable().

Commit 7d902c05b480 ("drm: Nuke drm_atomic_helper_connector_dpms")
removed drm_atomic_helper_connector_dpms() helper saying that it was a dead
code. It was however indirectly used by Exynos DRM driver for implementing
suspend/resume support. To fix this regression (after that patch Exynos DRM
suspend/resume functions became no-ops and hardware fails to suspend),
this patch rewrites them with drm_atomic_helper_suspend/resume() helpers.

replaced unsafe drm_for_each_connector() with drm_for_each_connector_iter()
and removed surrounding drm_modeset_lock calls. However, that lock was
there not only to protect unsafe drm_for_each_connector(), but it was also
required to be held by the dpms code which was called from the loop body.
This patch restores those drm_modeset_lock calls to fix broken suspend
and resume of Exynos DRM subsystem in v4.13 kernel.

This reverts commit bbdf0b2ff32a ("drm/i915/bxt: Disable device ready
before shutdown command").
Disable device ready before shutdown command was added previously to
avoid a split screen issue seen on dual link DSI panels. As of now, dual
link is not supported and will need some rework in the upstream
code. For single link DSI panels, the change is not required. This will
cause failure in sending SHUTDOWN packet during disable. Hence reverting
the change. Will handle the change as part of dual link enabling in
upstream.
