drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1

As far as I can tell the panel that was added in commit da50bd4258db
("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.

drm/bridge: ti-sn65dsi86: Remove the mystery delay

Let's solve the mystery of commit bf1178c98930 ("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.

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.

drm/i915/dp: Link train Fallback on eDP only if fallback link BW can fit panel's native mode

This patch fixes the original commit c0cfb10d9e1de49 ("drm/i915/edp:
Do not do link training fallback or prune modes on EDP") that causes
a blank screen in case of certain eDP panels (Eg: seen on Dell XPS13 9350)
where first link training fails and a retraining is required by falling
back to lower link rate/lane count.
In case of some panels they advertise higher link rate/lane count
than whats required for supporting the panel's native mode.
But we always link train at highest link rate/lane count for eDP
and if that fails we can still fallback to lower link rate/lane count
as long as the fallback link BW still fits the native mode to avoid
pruning the panel's native mode yet retraining at fallback values
to recover from a blank screen.

v3:
* Add const for fixed_mode (Ville)
v2:
* Send uevent if link failure on eDP unconditionally

drm/i915: Fix intel_dp_mst_best_encoder()

Currently, i915 appears to rely on blocking modesets on
no-longer-present MSTB ports by simply returning NULL for
->best_encoder(), which in turn causes any new atomic commits that don't
disable the CRTC to fail. This is wrong however, since we still want to
allow userspace to disable CRTCs on no-longer-present MSTB ports by
changing the DPMS state to off and this still requires that we retrieve
an encoder.

So, fix this by always returning a valid encoder regardless of the state
of the MST port.

Changes since v1:
- Remove mst atomic helper, since this got replaced with a much simpler
  solution

drm/i915: Skip vcpi allocation for MSTB ports that are gone

Since we need to be able to allow DPMS on->off prop changes after an MST
port has disappeared from the system, we need to be able to make sure we
can compute a config for the resulting atomic commit. Currently this is
impossible when the port has disappeared, since the VCPI slot searching
we try to do in intel_dp_mst_compute_config() will fail with -EINVAL.

Since the only commits we want to allow on no-longer-present MST ports
are ones that shut off display hardware, we already know that no VCPI
allocations are needed. So, hardcode the VCPI slot count to 0 when
intel_dp_mst_compute_config() is called on an MST port that's gone.

drm/i915: Don't unset intel_connector->mst_port

Currently we set intel_connector->mst_port to NULL to signify that the
MST port has been removed from the system so that we can prevent further
action on the port such as connector probes, mode probing, etc.
However, we're going to need access to intel_connector->mst_port in
order to fixup ->best_encoder() so that it can always return the correct
encoder for an MST port to prevent legacy DPMS prop changes from

always set and instead just check the status of
drm_connector->regustered to signify whether or not the connector has
disappeared from the system.

drm/i915: Use the correct crtc when sanitizing plane mapping

When we decide that a plane is attached to the wrong pipe we try
to turn off said plane. However we are passing around the crtc we
think that the plane is supposed to be using rather than the crtc
it is currently using. That doesn't work all that well because
we may have to do vblank waits etc. and the other pipe might
not even be enabled here. So let's pass the plane's current crtc to
intel_plane_disable_noatomic() so that it can its job correctly.

To do that semi-cleanly we also have to change the plane readout
to record the plane's visibility into the bitmasks of the crtc
where the plane is currently enabled rather than to the crtc
we want to use for the plane.

One caveat here is that our active_planes bitmask will get confused
if both planes are enabled on the same pipe. Fortunately we can use
plane_mask to reconstruct active_planes sufficiently since
plane_mask still has the same meaning (is the plane visible?)
during readout. We also have to do the same during the initial
plane readout as the second plane could clear the active_planes
bit the first plane had already set.

v2: Rely on fixup_active_planes() to populate active_planes fully (Daniel)
    Add Daniel's proposed comment to better document why we do this
    Drop the redundant intel_set_plane_visible() call

drm/i915: Check fb stride against plane max stride

commit 4e0b83a567e2 ("drm/i915: Extract per-platform plane->check()
functions") removed the plane max stride check for sprite planes.
I was going to add it back when introducing GTT remapping for the
display, but after further thought it seems better to re-introduce
it separately.

So let's add the max stride check back. And let's do it in a nicer
form than what we had before and do it for all plane types (easy
now that we have the ->max_stride() plane vfunc).

Only sprite planes really need this for now since primary planes
are capable of scanning out the current max fb size we allow, and
cursors have more stringent stride checks elsewhere.

drm/amd/amdgpu: Fix debugfs error handling

The error handling is wrong and "ent" could be NULL we when dereference
it to get "ent->d_inode".

The thing is that normally debugfs_create_file() is not supposed to
require (or have) any error handling.  That function does return error
pointers if debugfs is turned off but we know it's enable here.  When
it's enabled, then it returns NULL on error.

So what I did was I stripped out all the error handling except around
the i_size_write().  I could have just used a NULL check instead of an
IS_ERR_OR_NULL() but I figured this was more clear because that way you
don't have to look at the surrounding code to see whether debugfs is
enabled or not.

drm/nouveau: Start using new drm_dev initialization helpers

Per the documentation in drm_get_pci_dev(), this function is deprecated
and shouldn't be used anymore. As it turns out, we're going to need to
stop using drm_get_pci_dev() anyway in order to allow us to turn off the
card before full system shutdowns, otherwise we'll hit race conditions
with userspace while trying to tear down the card on shutdown.

So, start using drm_dev_get() and drm_dev_put(), and just turn our
load/unload callbacks into open coded init/fini() functions.

drm/nouveau: Refactor nvXX_backlight_init()

There's literally no difference between any of the backlight init
functions besides the backlight properties they set and the backlight
callbacks that they set, so move all of the duplicated backlight init
code out of there and into nouveau_backlight_init().

This gets rid of a lot of copy pasta!

Changes since v1:
- Some of the pre-refactor callbacks were storing nv_encoder in callback
  data for the backlight devices that they registered, as opposed to
  nouveau_drm. This got missed and caused some bugs that didn't
  originally appear on my setup (NULL kernel derefs) for some reason.
  So, fix this by finding the nouveau_encoder in
  nouveau_backlight_init(), and using that as the callback data for all
  gens instead even if they don't care about the encoder.

While I haven't actually gone into the details of what's causing this to
happen (maybe the kernel removes the backlight device in the device core
before we get to it?), it doesn't really matter anyway because the way
nouveau handles backlights has long since been deprecated.

According to the documentation on the drm_connector->late_register()
hook, the ->late_register() hook should be used for adding extra
connector-related devices. Vice versa, the ->early_unregister() hook is
meant to be used for removing those devices.

So: gut nouveau_drm->bl_list and nouveau_drm->backlight, and replace
them with per-connector backlight structures. Additionally, move
backlight registration/teardown into the ->late_register() and
->early_unregister() hooks so that DRM can give us a chance to remove
the backlight before the connector is even removed. This appears to fix
the problem once and for all.

Changes since v2:
- Use NV_INFO_ONCE for printing GMUX information, since otherwise this
  will end up printing that message for as many times as we have
  connectors

drm/amdgpu: Suppress keypresses from ACPI_VIDEO events

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.

   so check status.hw instand of status.valid in late_init.

drm/amdgpu: Limit the max mc address to hole start

For the vram_start is 0 case, the gart range will be from 0x0000FFFF00000000
to 0x0000FFFF1FFFFFFF, which will cause the engine hang.

So to avoid the hole, limit the max mc address to AMDGPU_GMC_HOLE_START.:wq
