commit 64912e997f upstream.
Polarity needs to be set accordingly to connector status (connected
or disconnected). Set it up in hpd_init() so first hotplug works
reliably no matter what is the initial set of connector. hpd_init()
also covers resume so HPD will work correctly after resume as well.

commit a18cee15ed upstream.
Allow the user to override whether MSIs are enabled
or not on supported ASICs. MSIs are disabled by default
on IGP chips as they tend not to work. However certain
IGP chips only seem to work with MSIs enabled.
I suspect this is a chipset or bios issue, but I'm not sure
what the proper fix is. This will at least make diagnosing
and working around the problem much easier.

commit 340764465a upstream.
Since force handling rework of d0d0a225e6
we could end up bouncing connector status btw disconnected and unknown.
When connector status change a call to output_poll_changed happen which
in turn ask again for detect but with force set.
So set the load detect flags whenever we report the connector as
connected or unknown this avoid bouncing btw disconnected and unknown.

Commit 9b9fe724 accidentally used RADEON_GPIO_EN_* where

commit d0d0a225e6 upstream.
When force == false, we don't do load detection in the connector
detect functions. Unforunately, we also return the previous
connector state so we never get disconnect events for DVI-I, DVI-A,
or VGA. Save whether we detected the monitor via load detection
previously and use that to determine whether we return the previous
state or not.

commit 5f0a26128d upstream.
DVI-D and HDMI-A are digital only, so there's no need to
attempt analog load detect. Also, skip bail before the
!force check, or we fail to get a disconnect events.
The next patches in the series attempt to fix disconnect
events for connectors with analog support (DVI-I, HDMI-B,
DVI-A).

commit f52c619a59 upstream.
The commit 47356eb672 introduced a
mechanism to record the backlight level only at disabling time, but it
also introduced a regression. Since intel_lvds_enable() may be called
without disabling (e.g. intel_lvds_commit() calls it unconditionally),
the backlight gets back to the last recorded value. For example, this
happens when you dim the backlight, close the lid and open the lid,
then the backlight suddenly goes to the brightest.
This patch fixes the bug by recording the backlight level always
when changed via intel_panel_set_backlight(). And,
intel_panel_{enable|disable}_backlight() call the internal function not
to update the recorded level wrongly.

Most asics just use the hw default value which requires
no explicit programming. For those that need a different
value, the vbios will program it properly. As such,
there's no need to program these registers explicitly
in the driver. Changing MC_SHARED_CHREMAP requires a reload
of all data in vram otherwise its contents will be scambled.

I was seeing a nasty 5 frame glitch every 10 seconds, caused by the
poll for connection on DVI attached by SDVO.
As my SDVO DVI supports hotplug detect interrupts, the fix is to
enable them, and hook them in to the various bits of driver
infrastructure so that they work reliably.
Note that this is only tested on single-function DVI-D SDVOs, on two
platforms (965GME and 945GSE), and has not been checked against a
specification document.

We want to enable dithering on any pipe where the frame buffer has
more color resolution than the output device.
The previous code was incorrectly clamping the frame buffer bpc to the
display bpc, effectively disabling dithering all of the time as the
computed frame buffer bpc would never be larger than the display bpc.
