commit f71800228dc74711c3df43854ce7089562a3bc2d upstream.
The TVE200 will occasionally print a bunch of lost interrupts
and similar dmesg messages, sometimes during boot and sometimes
after disabling and coming back to enablement. This is probably
because the hardware is left in an unknown state by the boot
loader that displays a logo.
This can be fixed by bringing the controller into a known state
by resetting the controller while enabling it. We retry reset 5
times like the vendor driver does. We also put the controller
into reset before de-clocking it and clear all interrupts before
enabling the vblank IRQ.
This makes the video enable/disable/enable cycle rock solid
on the D-Link DIR-685. Tested extensively.

[ Upstream commit d98299885c9ea140c1108545186593deba36c4ac ]
On my R9 390, the voltage was reported as a constant 1000 mV.
This was due to a bug in smu7_hwmgr.c, in the smu7_read_sensor()
function, where some magic constants were used in a condition,
to determine whether the voltage should be read from PLANE2_VID
or PLANE1_VID. The VDDC mask was incorrectly used, instead of
the VDDGFX mask.
This patch changes the code to use the correct defined constants
(and apply the correct bitshift), thus resulting in correct voltage reporting.

[ Upstream commit 168f09cdadbd547c2b202246ef9a8183da725f13 ]
[Why]
These aren't stable on some platform configurations when driving
multiple displays, especially on higher resolution.
In particular the delay in asserting p-state and validating from
x86 outweights any power or performance benefit from the hardware
composition.
Under some configurations this will manifest itself as extreme stutter
or unresponsiveness especially when combined with cursor movement.
[How]
Disable these for now. Exposing overlays to userspace doesn't guarantee
that they'll be able to use them in any and all configurations and it's
part of the DRM contract to have userspace gracefully handle validation
failures when they occur.
Valdiation occurs as part of DC and this in particular affects RV, so
disable this in dcn10_global_validation.

this state change is enough to trigger the required TS cache flush. As
the BLT engine is completely asychronous, we also need a few more stall
