105f20706f drm/ttm: Provide ttm_bo_global_{init/release}() for struct ttm_bo_global
So far, struct ttm_bo_global_ref was the only way of initializing a struct
ttm_bo_global. Providing separate initializer and release functions for
struct ttm_bo_global gives drivers the option of implementing their own
init and release callbacks for drm_global_references of type
DRM_GLOBAL_TTM_BO.

The original functions for initializing and releasing via struct
ttm_bo_global_ref are wrappers around the new interfaces.

e55a5c9b5f drm/ttm: Rename ttm_bo_global_{init,release}() to ttm_bo_global_ref_{,}()
The functions ttm_bo_global_init() and ttm_bo_global_release() do not
receive an argument of type struct ttm_bo_global. Both take a struct
drm_global_reference that contains points to a struct ttm_bo_global_ref.

98e90a34cc drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part2
[Why]
In DCN we want direct DAL to SMU calls, with as little as possible
interference by pplib. The reason for each pp_smu interface mapping to
1 SMU message is so we can have the sequencing of different SMU message
in dal and shared across different OS. This will also simplify
debugging as DAL owns this interaction and there's no confusion about
division of ownership.

[How]
Part 2: Separate set_min_deep_sleep_dcfclk message from the SMU
messages that are sent as part of dm_pp_apply_clock_for_voltage_request.

9d064be1e6 drm/amdgpu: revert "enable gfxoff in non-sriov and stutter mode by default"
This is still completely breaking my Raven system.

This reverts commit cdf2f910fa969adca1b0e3ad2b487821233dc038.

Revert until we sort out the sbios and firmware combinations that work
correctly.

734afd4b21 drm/amdgpu: Fix skipping hangged job reset during gpu recover.
Problem:
During GPU recover DAL would hang in
amdgpu_pm_compute_clocks->amdgpu_fence_wait_empty

Fix:
Turns out there was a typo introduced by
3320b8d drm/amdgpu: remove job->ring which caused skipping
amdgpu_fence_driver_force_completion and so the hangged job
was never force signaled and this would cause the hang later in DAL.

0cafc82fae drm/amd/display: set backlight level limit to 1
This patch will work as workaround for silicon limitation
related to PWM dutycycle when the backlight level goes to 0.

Actually PWM value is 16 bit value and valid range from 1-65535.
when ever user requested to set this PWM value to 0 which is not
fall in the range, in VBIOS taken care this by limiting to 1.
This patch here will do the same. Either driver or VBIOS can not
pass 0 value as it is not a valid range for PWM and it will
give a high PWM pulse which is not the intended behaviour as
per HW constraints.

8f054b6f53 drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1
As far as I can tell the panel that was added in commit da50bd4258
("drm/panel: simple: Add Innolux TV123WAM panel driver support")
wasn't actually an Innolux TV123WAM but was actually an Innolux
P120ZDG-BF1.

As far as I can tell the Innolux TV123WAM isn't a real panel and but
it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1.
Let's unmosh.

Here's my evidence:

* Searching for TV123WAM on the Internet turns up a TI panel.  While
  it's possible that an Innolux panel has the same model number as the
  TI Panel, it seems a little doubtful.  Looking up the datasheet from
  the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm.

* As far as I know, the patch adding the Innolux Panel was supposed to
  be for the board that's sitting in front of me as I type this
  (support for that board is not yet upstream).  On the back of that
  panel I see Innolux P120ZDZ-EZ1 rev B1.

* Someone pointed me at a datasheet that's supposed to be for the
  panel in front of me (sorry, I can't share the datasheet).  That
  datasheet has the string "p120zdg-bf1"

* If I search for "P120ZDG-BF1" on the Internet I get hits for panels
  that are 2160x1440.  They don't have datasheets, but the fact that
  the resolution matches is a good sign.

In any case, let's update the name and also the physical size to match
the correct panel.

c2bfc22388 drm/bridge: ti-sn65dsi86: Remove the mystery delay
Let's solve the mystery of commit bf1178c989 ("drm/bridge:
ti-sn65dsi86: Add mystery delay to enable()").  Specifically the
reason we needed that mystery delay is that we weren't paying
attention to HPD.

Looking at the datasheet for the same panel that was tested for the
original commit, I see there's a timing "t3" that times from power on
to the aux channel being operational.  This time is specced as 0 - 200
ms.  The datasheet says that the aux channel is operational at exactly
the same time that HPD is asserted.

Scoping the signals on this board showed that HPD was asserted 84 ms
after power was asserted.  That very closely matches the magic 70 ms
delay that we had.  ...and actually, in my testing the 70 ms wasn't
quite enough of a delay and some percentage of the time the display
didn't come up until I bumped it to 100 ms (presumably 84 ms would
have worked too).

To solve this, we tried to hook up the HPD signal in the bridge.
...but in doing so we found that that the bridge didn't report that
HPD was asserted until ~280 ms after we powered it (!).  This is
explained by looking at the sn65dsi86 datasheet section "8.4.5.1 HPD
(Hot Plug/Unplug Detection)".  Reading there we see that the bridge
isn't even intended to report HPD until 100 ms after it's asserted.
...but that would have left us at 184 ms.  The extra 100 ms
(presumably) comes from this part in the datasheet:

> The HPD state machine operates off an internal ring oscillator. The
> ring oscillator frequency will vary [ ... ]. The min/max range in
> the HPD State Diagram refers to the possible times based off
> variation in the ring oscillator frequency.

Given that the 280 ms we'll end up delaying if we hook up HPD is
_slower_ than the 200 ms we could just hardcode, for now we'll solve
the problem by just hardcoding a 200 ms delay in the panel driver
using the patch in this series ("drm/panel: simple: Support panels
with HPD where HPD isn't connected").

If we later find a panel that needs to use this bridge where we need
HPD then we'll have to come up with some new code to handle it.  Given
the silly debouncing in the bridge chip, though, it seems unlikely.

One last note is that I tried to solve this through another way: In
ti_sn_bridge_enable() I tried to use various combinations of
dp_dpcd_writeb() and dp_dpcd_readb() to detect when the aux channel
was up.  In theory that would let me detect _exactly_ when I could
continue and do link training.  Unfortunately even if I did an aux
transfer w/out waiting I couldn't see any errors.  Possibly I could
keep looping over link training until it came back with success, but
that seemed a little overly hacky to me.

2ed3e9510f drm/panel: simple: Support panels with HPD where HPD isn't connected
Some eDP panels that are designed to be always connected to a board
use their HPD signal to signal that they've finished powering on and
they're ready to be talked to.

However, for various reasons it's possible that the HPD signal from
the panel isn't actually hooked up.  In the case where the HPD isn't
hooked up you can look at the timing diagram on the panel datasheet
and insert a delay for the maximum amount of time that the HPD might
take to come up.

Let's add support in simple-panel for this concept.

At the moment we will co-opt the existing "prepare" delay to keep
track of the delay and we'll use a boolean to specify that a given
panel should only apply the delay if the "no-hpd" property was
specified.
