Pull documentation build warning fixes from Jonathan Corbet:
"This contains a series of warning fixes from Mauro; once applied, the
number of warnings from the once-noisy docs build process is nearly
zero.
Getting to this point has required a lot of work; once there,
hopefully we can keep things that way.
I have packaged this as a separate pull because it does a fair amount
of reaching outside of Documentation/. The changes are all in comments
and in code placement. It's all been in linux-next since last week"

While I thought I had this correct (since it actually did reject modes
like I expected during testing), Ville Syrjala from Intel pointed out
that the logic here isn't correct. max_clock refers to the max data rate
supported by the DP encoder. So, limiting it to the output of ds_clock (which
refers to the maximum dotclock of the downstream DP device) doesn't make any
sense. Additionally, since we're using the connector's bpc as the canonical BPC
we should use this in mode_valid until we support dynamically setting the bpp
based on bandwidth constraints.
https://lists.freedesktop.org/archives/dri-devel/2020-September/280276.html
For more info.
So, let's rewrite this using Ville's advice.
v2:
* Ville pointed out I mixed up the dotclock and the link rate. So fix that...
* ...and also rename all the variables in this function to be more appropriately
labeled so I stop mixing them up.
* Reuse the bpp from the connector for now until we have dynamic bpp selection.
* Use use DIV_ROUND_UP for calculating the mode rate like i915 does, which we
should also have been doing from the start

Ville also pointed out that I got a lot of the logic here wrong as well, whoops.
While I don't think anyone's likely using 3D output with nouveau, the next patch
will make nouveau_conn_mode_valid() make a lot less sense. So, let's just get
rid of it and open-code it like before, while taking care to move the 3D frame
packing calculations on the dot clock into the right place.

Not entirely sure why this never came up when I originally tested this
(maybe some BIOSes already have this setup?) but the ->caps_init vfunc
appears to cause the display engine to throw an exception on driver
init, at least on my ThinkPad P72:
nouveau 0000:01:00.0: disp: chid 0 mthd 008c data 00000000 0000508c 0000102b
This is magic nvidia speak for "You need to have the DMA notifier offset
programmed before you can call NV507D_GET_CAPABILITIES." So, let's fix
this by doing that, and also perform an update afterwards to prevent
racing with the GPU when reading capabilities.
v2:
* Don't just program the DMA notifier offset, make sure to actually
perform an update
v3:
* Don't call UPDATE()
* Actually read the correct notifier fields, as apparently the
CAPABILITIES_DONE field lives in a different location than the main
NV_DISP_CORE_NOTIFIER_1 field. As well, 907d+ use a different
CAPABILITIES_DONE field then pre-907d cards.
v4:
* Don't forget to check the return value of core507d_read_caps()
v5:
* Get rid of NV50_DISP_CAPS_NTFY[14], use NV50_DISP_CORE_NTFY
* Disable notifier after calling GetCapabilities()

Restore RPS for ILK-M. We lost it when an extra HAS_RPS()
check appeared in intel_rps_enable().
Unfortunaltey this just makes the performance worse on my
ILK because intel_ips insists on limiting the GPU freq to
the minimum. If we don't do the RPS init then intel_ips will
not limit the frequency for whatever reason. Either it can't
get at some required information and thus makes wrong decisions,
or we mess up some weights/etc. and cause it to make the wrong
decisions when RPS init has been done, or the entire thing is
just wrong. Would require a bunch of reverse engineering to
figure out what's going on.

We are incorrectly limiting the max allocation size as per the mm
max_order, which is effectively the largest power-of-two that we can fit
in the region size. However, it's normal to setup the region or
allocator with a non-power-of-two size(for example 3G), which we should
already handle correctly, except it seems for the early too-big-check.
v2: make sure we also exercise the I915_BO_ALLOC_CONTIGUOUS path, which
is quite different, since for that we are actually limited by the
largest power-of-two that we can fit within the region size. (Chris)

Most of the helpers to retrieve vc4 structures from the DRM base structures
rely on the fact that the first member of the vc4 structure is the DRM one
and just cast the pointers between them.
However, this is pretty fragile especially since there's no check to make
sure that the DRM structure is indeed at the offset 0 in the structure, so
let's use container_of to make it more robust.

When we forward an mmap to the dma_buf exporter, they get to own
everything. Unfortunately drm_gem_mmap_obj() overwrote
vma->vm_private_data after the driver callback, wreaking the
exporter complete. This was noticed because vb2_common_vm_close blew
up on mali gpu with panfrost after commit 26d3ac3cb04d
("drm/shmem-helpers: Redirect mmap for imported dma-buf").
Unfortunately drm_gem_mmap_obj also acquires a surplus reference that
we need to drop in shmem helpers, which is a bit of a mislayer
situation. Maybe the entire dma_buf_mmap forwarding should be pulled
into core gem code.
Note that the only two other drivers which forward mmap in their own
code (etnaviv and exynos) get this somewhat right by overwriting the
gem mmap code. But they seem to still have the leak. This might be a
good excuse to move these drivers over to shmem helpers completely.

When running the trigger hook, ALSA by default will take a spinlock, and
thus will run the trigger hook in atomic context.
However, our HDMI driver will send the infoframes as part of the trigger
hook, and part of that process is to wait for a bit to be cleared for up to
100ms. To be nicer to the system, that wait has some usleep_range that
interact poorly with the atomic context.
There's several ways we can fix this, but the more obvious one is to make
ALSA take a mutex instead by setting the nonatomic flag on the DAI link.
That doesn't work though, since now the cyclic callback installed by the
dmaengine helpers in ALSA will take a mutex, while that callback is run by
dmaengine's virt-chan code in a tasklet where sleeping is not allowed
either.
Given the delay we need to poll the bit for, changing the usleep_range for
a udelay and keep running it from a context where interrupts are disabled
is not really a good option either.
However, we can move the infoframe setup code in the hw_params hook, like
is usually done in other HDMI controllers, that isn't protected by a
spinlock and thus where we can sleep. Infoframes will be sent on a regular
basis anyway, and since hw_params is where the audio parameters that end up
in the infoframes are setup, this also makes a bit more sense.

- Unify the kgdb_breakpoint() call
- Drop the non-existing CONFIG_HAVE_KGDB
Also align the behavior of ASSERT() macro in both cases with and
without CONFIG_DEBUG_KERNEL_DC.

ASSERT_CRITICAL() invokes kgdb_breakpoint() whenever either
CONFIG_KGDB or CONFIG_HAVE_KGDB is set. This, however, may lead to a
kernel panic when no kdb stuff is attached, since the
kgdb_breakpoint() call issues INT3. It's nothing but a surprise for
normal end-users.
For avoiding the pitfall, make the kgdb_breakpoint() call only when
CONFIG_DEBUG_KERNEL_DC is set.

Currently both error code paths handled in dal_gpio_open_ex() issues
ASSERT_CRITICAL(), and this leads to a kernel panic unnecessarily if
CONFIG_KGDB is enabled. Since basically both are non-critical errors
and can be recovered, drop those assert calls and use a safer one,
BREAK_TO_DEBUGGER(), for allowing the debugging, instead.

When using the scaler on the A10-like frontend with single-planar formats,
the current code will setup the channel 0 filter (used for the R or Y
component) with a different phase parameter than the channel 1 filter (used
for the G/B or U/V components).
This creates a bleed out that keeps repeating on of the last line of the
RGB plane across the rest of the display. The Allwinner BSP either applies
the same phase parameter over both channels or use a separate one, the
condition being whether the input format is YUV420 or not.
Since YUV420 is both subsampled and multi-planar, and since YUYV is
subsampled but single-planar, we can rule out the subsampling and assume
that the condition is actually whether the format is single or
multi-planar. And it looks like applying the same phase parameter over both
channels for single-planar formats fixes our issue, while we keep the
multi-planar formats working properly.

The scaler filter phase setup in the allwinner kernel has two different
cases for setting up the scaler filter, the first one using different phase
parameters for the two channels, and the second one reusing the first
channel parameters on the second channel.
The allwinner kernel has a third option where the horizontal phase of the
second channel will be set to a different value than the vertical one (and
seems like it's the same value than one used on the first channel).
However, that code path seems to never be taken, so we can ignore it for
now, and it's essentially what we're doing so far as well.
Since we will have always the same values across each components of the
filter setup for a given channel, we can simplify a bit our frontend
structure by only storing the phase value we want to apply to a given
channel.

will stay blank. Deassert in prepare() and assert in unprepare() to keep
