commit b52b6738cc2d50d2a8f4d0095bcb5a86716008a5 upstream.

Some power features rely on the driver loaded version so always
load the MC firmware from the driver even if the vbios loaded
a version already.

[ Upstream commit 69756c6ff0de478c10100481f16c966dde3b5339 ]

[Why]
Many panels support more than 8bpc but some modes are unavailable while
running at greater than 8bpc due to DP/HDMI bandwidth constraints.

Support for more than 8bpc was added recently in the driver but it
defaults to the maximum supported bpc - locking out these modes.

This should be a user configurable option such that the user can select
what bpc configuration they would like.

[How]
This patch introduces the "max bpc" amdgpu driver specific connector
property so the user can limit the maximum bpc. It ranges from 8 to 16.

This doesn't directly set the preferred bpc for the panel since it
follows Intel's existing driver conventions.

This proprety should be removed once common drm support for max bpc
lands.

[ Upstream commit c837243ff4017f493c7d6f4ab57278d812a86859 ]

The bug limits the IH ring wptr address to 40bit. When the system memory
is bigger than 1TB, the bus address is more than 40bit, this causes the
interrupt cannot be handled and cleared correctly.

Due to lack of MODULE_FIRMWARE() with hainan_mc.bin, the driver
doesn't work properly in initrd.  Let's add it.

commit 582f58de36834096a91cc1de2540c2f7269f850d upstream.

Currently we return NOTIFY_DONE for any event which we don't think is
ours. However, many laptops will send more then just an ATIF event and
will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't
check for this, we return NOTIFY_DONE which causes a keypress for the
ACPI event to be propogated to userspace. This is the equivalent of
someone pressing the display key on a laptop every time there's a
hotplug event.

So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses
from them.
