Enable stereoscopic output for HDMI and DisplayPort connectors on
NV50+ (G80+) hardware.  We do not enable stereoscopy on older
hardware in case there is some older board that still has HDMI
output but for which we have no logic for setting the Vendor
InfoFrame.

With this, I get an obvious 3D output when using the "testdisplay"
program from intel-gpu-tools with the "-3" parameter and outputting
to a 3D-capable HDMI display, for all available 3D modes (be they
TB, SBSH, or FP) on all four G80+ DISPs.

Frame-packing modes add an extra vtotal raster lines to each frame
above and beyond what the basic mode description calls for.
Account for this during scaler configuration (possibly a bit of a
hack), during CRTC configuration (clearly not a hack), and when
checking that a mode is valid for a given connector (cribbed from
the i915 driver).

HDMI InfoFrames are passed to NVKM as bags of bytes, but the
hardware needs them to be packed into words.  Rather than having
four (or more) copies of the packing logic introduce a single copy
now, in a central place.

We currently need these for AVI and Vendor InfoFrames, but we may
also expect to need them for Audio InfoFrames at some point.

The nouveau driver, in the Linux 3.7 days, used to try and set the
AVI InfoFrame based on the selected display mode.  These days, it
uses a fixed set of InfoFrames.  Start to correct that, by
providing a mechanism whereby InfoFrame data may be passed to the
NVKM functions that do the actual configuration.

At this point, only establish the new parameters and their parsing,
don't actually use the data anywhere yet (since it's not supplied
anywhere).

drm_mode_set_crtcinfo() does compensation for interlace and
doublescan timing effects already, so do it first and use the
compensated figures instead of the constant "vscan / ilace" terms
that we had before.

And then it turns out that the hardware model for how the timing
parameters are configured is basically the standard model, but
starting one clock before the sync pulse rather than at the start
of the display area, which lets us drastically simplify the
overall timing calculations (verifying the changes by algebraic
operations is left as an exercise for the reader).

Finally, there were a couple of issues with the computation of
m->v.blankus that are addressed here.  Interlaced modes would
generate a negative intermediate result.  Double scan modes would
generate an overestimate rather than an underestimate.  And when
enabling frame-packing modes, a rather extreme overestimate would
be generated.  Fixed, by using the timings as adjusted for the
CRTC to find the length of the vertical blanking period instead of
mixing adjusted and pre-adjustment timing parameters.

Linux 4.12-rc5 for nouveau fixes

imx-drm: cleanups and YUV 4:2:0 memory read/write reduction support

- Remove counter load enable form PRE, which has no effect.
- Add support for setting the double read/write reduction flag in channel
  parameter memory. This can be used to save some memory bandwidth when
  capturing in YUV 4:2:0 chroma subsampled formats.
- Allocate DMA channel structures as needed, most of the 64 channels are
  unused or even reserved.
- Remove unused interrupt busy waiting routine.
- Set VDIC field order for both AUTO and MAN inputs simultaneously as
  both can't be active at the same time.

sun4i-drm changes for 4.13

An unusually big pull request for this merge window, with three notable
features:
  - V3s display engine support. This is especially notable because it uses
    a different display engine used on the newer Allwinner SoCs (H3, A64
    and the likes) that will be quite easily supported now.
  - HDMI support for the old Allwinner SoCs. This is enabled only on the
    A10s for now, but should be really easy to extend to deal with A10, A20
    and A31
  - Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3,
    etc.). It currently ignores the second pipeline, but we can use the
    dual-pipelines bindings. This will be useful to enable the display
    pipeline while we work on the dual-pipeline.

According to the eLCDIF initialization steps listed in the MX6SX
Reference Manual the eLCDIF block reset is mandatory.

Without performing the eLCDIF reset the display shows garbage content
when the kernel boots.

In earlier tests this issue has not been observed because the bootloader
was previously showing a splash screen and the bootloader display driver
does properly implement the eLCDIF reset.

Add the eLCDIF reset to the driver, so that it can operate correctly
independently of the bootloader.

Tested on a imx6sx-sdb board.
