It's better to perform the sync at the very last of the suspend
instead of the pipe-disable function, so that we can catch all pending
URBs (if any).
While we're at it, drop the error code from udl_sync_pending_urb()
since we basically ignore it; instead, give a clear error message
indicating a problem.

In the current design, udl_get_urb() may be called asynchronously
during the driver freeing its URL list via udl_free_urb_list().
The problem is that the sync is determined by comparing the urbs.count
and urbs.available fields, while we clear urbs.count field only once
after udl_free_urb_list() finishes, i.e. during udl_free_urb_list(),
the state becomes inconsistent.
For fixing this inconsistency and also for hardening the locking
scheme, this patch does a slight refactoring of the code around
udl_get_urb() and udl_free_urb_list(). Now urbs.count is updated in
the same spinlock at extracting a URB from the list in
udl_free_url_list().

Restore the display mode whne resuming from suspend. Currently, the
display remains dark.
On resume, the CRTC's mode does not change, but the 'active' flag
changes to 'true'. Taking this into account when considering a mode
switch restores the display mode.
The bug is reproducable by using Gnome with udl and observing the
adapter's suspend/resume behavior.
Actually, the whole check added in udl_simple_display_pipe_enable()
about the crtc_state->mode_changed was bogus. We should drop the
whole check and always apply the mode change in this function.
[ tiwai -- Drop the mode_changed check entirely instead, per Daniel's
suggestion ]

While we have multiple test cases, most of them check multiple
conditions, calling the function that is tested multiple times with
different arguments (with comments that indicate test case boundary).
This usually means that it can be easily converted into multiple test
cases.

Fix gnome-shell (and other page-flip users) hanging after suspend/resume
because of the gma500's IRQs not working.
This fixes 2 problems with the IRQ handling:
1. gma_power_off() calls gma_irq_uninstall() which does a free_irq(), but
gma_power_on() called gma_irq_preinstall() + gma_irq_postinstall() which
do not call request_irq. Replace the pre- + post-install calls with
gma_irq_install() which does prep + request + post.
2. After fixing 1. IRQs still do not work on a Packard Bell Dot SC (Intel
Atom N2600, cedarview) netbook.
Cederview uses MSI interrupts and it seems that the BIOS re-configures
things back to normal APIC based interrupts during S3 suspend. There is
some MSI PCI-config registers save/restore code which tries to deal with
this, but on the Packard Bell Dot SC this is not sufficient to restore
MSI IRQ functionality after a suspend/resume.
Replace the PCI-config registers save/restore with pci_disable_msi() on
suspend + pci_enable_msi() on resume. Fixing e.g. gnome-shell hanging.

VPP_WRAP_OSD1_MATRIX_COEF22.Coeff22 is documented as being bits 0-12,
not 16-28.
Without this the output tends to have a pink hue, changing it results
in better color accuracy.
The vendor kernel doesn't use this register. However the code which
sets VIU2_OSD1_MATRIX_COEF22 also uses bits 0-12. There is a slightly
different style of registers for configuring some of the other matrices,
which do use bits 16-28 for this coefficient, but those have names
ending in MATRIX_COEF22_30, and this is not one of those.

Commit 52824ca450 ("drm/panel-edp: Better describe eDP panel delays")
clarified the various delays used for eDP panels, tying them to the eDP
panel timing diagram.
For Innolux N116BCA-EA1, .prepare_to_enable would be:
t4_min + t5_min + t6_min + max(t7_max, t8_min)
Since t4_min and t5_min are both 0, the panel can use either .enable or
.prepare_to_enable.
As .enable is better defined, switch to using .enable for this panel.
Also add .disable = 50, based on the datasheet's t9_min value. This
effectively makes the delays the same as delay_200_500_e80_d50.

On BDW+ M/N are double buffered and so we can easily reprogram them
during a fastset. So for eDP panels that support seamless DRRS we
can just change these without a full modeset.
For earlier platforms we'd need to play tricks with M1/N1 vs.
M2/N2 during the fastset to make sure we do the switch atomically.
Not sure the added complexity is worth the hassle, so leave it
alone for now.
The slight downside is that we have to keep the link running at
a link rate capable of supporting the highest refresh rate we
want to use. For the moment we just pick the highest mode the
panel reports and calculate the link based on that. This might
need further refinement (eg. if we run into bandwidth
restrictions)...
v2: Only use the high link rate if the platform really supports
the seamless M/N change uring fastset (ie. bdw+)
v3: Rebase due to HAS_DOUBLE_BUFFERED_M_N()

Add a function to get the fixed_mode with the highest clock.
The plan is to use this for the link bw calculation on seamless
DRRS panels so that we alwasy end up with the same link params
regardless of the requested refresh rate. This will allow fastset
to do seamless refresh rate changes based on userspace request
instead of having to go for a full modeset.

To make the fastboot checks at least somewhat sensible let's mark
the expected DPLL as the active one right after we finished the
state computation. Otherwise intel_pipe_config_compare() will
always be comparing things against NULL/0.
TODO: This is still not really right. If the previous commit
had to fall back to the other PLL then the comparisong will
now fail. I guess intel_pipe_config_compare() should rather
be comparing port_dplls[] instead. But to do that we really
should just unify every platform to use the port_dplls[]
approach whether they have any need for PLL fallbacks or not.
