Seems to be stable on them.  There are still some issues
with the performance states staying in the highest levels
on certain cards when multiple monitors are attached, but
being that the the cards are always in their highest power
state at boot up anyway, this doesn't really change anything
and improves things in all other cases.

On SI asics, the SMC will automatically force the performance
level to the lowest level if there are no displays active.  This
prevents automatic performance scaling on PowerXpress systems or
for offscreen rendering or compute when displays are disabled.

Going forward, it would be best to dynamically change this, but
for now leave scaling enabled.

The FMT blocks control how data is sent from the backend
of the display pipe to to monitor.  Proper set up of the
FMT blocks are required for 30bpp formats.  Additionally,
dithering can be enabled on for better display with 18 and
24bpp displays.  The exception is LVDS/eDP which atom
takes care of in the SelectCRTC_Source table.  For now
just enable truncation until we test dithering more.

  the maintainer this is really big.
- HDMI audio fix from Jani.
- VLV dpll computation code refactoring from Ville.
- Fixups for the gpu booster from last time around (Chris).
- Some cleanups in the context code from Ben.
- More watermark work from Ville (we'll be getting there ...).
- vblank timestamp improvements from Ville.
- CONFIG_FB=n support, including drm core changes to make the fbdev
  helpers optional.
- DP link training improvements (Jani).
- mmio vtable from Ben, prep work for future hw.

To disable a monitor, a Spice client sends a monitor config with the
monitor resolution to 0x0.

However, before qxl_crtc_disable() is reached after the hotplug event,
it can happen that another monitor is reconfigured, and
qxl_send_monitors_config() is called with the old config, which will
re-enable the monitor on the client.

Reset config if monitor is found disconnected, during
drm_helper_hpd_irq_event().

By default, 1024x768 is the preferred resolution. However, when a
monitor config is given, it should be the only preferred resolution.

Note that the monitor config resolution is passed to
qxl_add_common_modes() to avoid adding a duplicate mode without the
preferred resolution. That would discard the previous monitor config
preferred bit.

In commit 38d5487d, Keith explained:
    This patch simply merges the two mode type bits together; that seems
    reasonable to me, but perhaps only a subset of the bits should be
    used? None of these can be user defined as they all come from
    looking at just the hardware.

However, merging the bits means that a flag becomes sticky. It is not
possible, for example to update the mode type to remove the
DRM_MODE_TYPE_PREFERRED bit.

After a brief discussion with Dave Airlie on irc, it was agreed to
propose that change, instead of introducing another function to remove a
bit from exisiting modes type.

This adds support for the Armada 510 display subsystem found on the
Marvell Dove devices.  This IP is re-used across several different Marvell
SoCs with various tweaks, and this driver has been structured to allow
the other IPs to re-use the bulk of this code; further work in this area
is expected from interested parties.

This has been extensively tested on the SolidRun Cubox platform and
appears to work well there.
