misc i915 fixes.
* tag 'drm-intel-fixes-2015-05-08' of git://anongit.freedesktop.org/drm-intel:
drm/i915: Drop PIPE-A quirk for 945GSE HP Mini
drm/i915: Sink rate read should be saved in deca-kHz
drm/i915/dp: there is no audio on port A
drm/i915: Add missing MacBook Pro models with dual channel LVDS
drm/i915: Assume dual channel LVDS if pixel clock necessitates it
Since commit 844b03f277 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

Tegra would not only need a hardware vblank counter that
increments at leading edge of vblank, but also support
for instantaneous high precision vblank timestamp queries, ie.
a proper implementation of dev->driver->get_vblank_timestamp().
Without these, there can be off-by-one errors during vblank
disable/enable if the scanout is inside vblank at en/disable
time, and additionally clients will never see any useable
vblank timestamps when querying via drmWaitVblank ioctl. This
would negatively affect swap scheduling under X11 and Wayland.

Single channel LVDS maxes out at 112 MHz. The 15" pre-retina models
shipped with 1440x900 (106 MHz) by default or 1680x1050 (119 MHz)
as a BTO option, both versions used dual channel LVDS even though
the smaller one would have fit into a single channel.
Notes:
Bug report showing that the MacBookPro8,2 with 1440x900 uses dual
channel LVDS (this lead to it being hardcoded in intel_lvds.c by
Daniel Vetter with commit 618563e394):
https://bugzilla.kernel.org/show_bug.cgi?id=42842
If i915.lvds_channel_mode=2 is missing even though the machine needs
it, every other vertical line is white and consequently, only the left
half of the screen is visible (verified by myself on a MacBookPro9,1).
Forum posting concerning a MacBookPro6,2 with 1440x900, author is
using i915.lvds_channel_mode=2 on the kernel command line, proving
that the machine uses dual channels:
https://bbs.archlinux.org/viewtopic.php?id=185770
Chi Mei N154C6-L04 with 1440x900 is a replacement panel for all
MacBook Pro "A1286" models, and that model number encompasses the
MacBookPro6,2 / 8,2 / 9,1. Page 17 of the panel's datasheet shows it's
driven with dual channel LVDS:
http://www.ebay.com/itm/-/400690878560http://www.everymac.com/ultimate-mac-lookup/?search_keywords=A1286http://www.taopanel.com/chimei/datasheet/N154C6-L04.pdf
Those three 15" models, MacBookPro6,2 / 8,2 / 9,1, are the only ones
with i915 graphics and dual channel LVDS, so that list should be
complete. And the 8,2 is already in intel_lvds.c.
Possible motivation to use dual channel LVDS even on the 1440x900
models: Reduce the number of different parts, i.e. use identical logic
boards and display cabling on both versions and the only differing
component is the panel.

Single channel LVDS maxes out at 112 MHz, anything above must be dual
channel. This avoids the need to specify i915.lvds_channel_mode=2 on
all 17" MacBook Pro models with i915 graphics since they had 1920x1200
(193 MHz), plus those 15" pre-retina models which had a resolution
of 1680x1050 (119 MHz) as a BTO option.
Source for 112 MHz limit of single channel LVDS is section 2.3 of:
https://01.org/linuxgraphics/sites/default/files/documentation/ivb_ihd_os_vol3_part4.pdf
v2: Avoid hardcoding 17" models by assuming dual channel LVDS if the

WaIdleLiteRestore is an execlists-only workaround, and requires the driver
to ensure that any context always has HEAD!=TAIL when attempting lite
restore.
Add two extra MI_NOOP instructions at the end of each request, but keep
the requests tail pointing before the MI_NOOPs. We may not need to
executed them, and this is why request->tail is sampled before adding
these extra instructions.
If we submit a context to the ELSP which has previously been submitted,
move the tail pointer past the MI_NOOPs. This ensures HEAD!=TAIL.
v2: Move overallocation to gen8_emit_request, and added note about
sampling request->tail in commit message (Chris).
v3: Remove redundant request->tail assignment in __i915_add_request, in
