Now that we've extracted i915's code for reading both the normal DPCD
caps and extended DPCD caps into a shared helper, let's start using this
in nouveau to enable us to start checking extended DPCD caps for free.

Since DP 1.3, it's been possible for DP receivers to specify an
additional set of DPCD capabilities, which can take precedence over the
capabilities reported at DP_DPCD_REV.
Basically any device supporting DP is going to need to read these in an
identical manner, in particular nouveau, so let's go ahead and just move
this code out of i915 into a shared DRM DP helper that we can use in
other drivers.
v2:
* Remove redundant dpcd[DP_DPCD_REV] == 0 check
* Fix drm_dp_dpcd_read() ret checks

Currently in nouveau_connector_ddc_detect() and
nouveau_connector_detect_lvds(), we start the connector probing process
by releasing the previous EDID and informing DRM of the change. However,
since commit 5186421cbfe2 ("drm: Introduce epoch counter to
drm_connector") drm_connector_update_edid_property() actually checks
whether the new EDID we've specified is different from the previous one,
and updates the connector's epoch accordingly if it is. But, because we
always set the EDID to NULL first in nouveau_connector_ddc_detect() and
nouveau_connector_detect_lvds() we end up making DRM think that the EDID
changes every single time we do a connector probe - which isn't needed.
So, let's fix this by not clearing the EDID at the start of the
connector probing process, and instead simply changing or removing it
once near the end of the probing process. This will help prevent us from
sending unneeded hotplug events to userspace when nothing has actually
changed.

This is another bit that we never implemented for nouveau: dongle
detection. When a "dongle", e.g. an active display adaptor, is hooked up
to the system and causes an HPD to be fired, we don't actually know
whether or not there's anything plugged into the dongle without checking
the sink count. As a result, plugging in a dongle without anything
plugged into it currently results in a bogus EDID retrieval error in the kernel log.
Additionally, most dongles won't send another long HPD signal if the
user suddenly plugs something in, they'll only send a short HPD IRQ with
the expectation that the source will check the sink count and reprobe
the connector if it's changed - something we don't actually do. As a
result, nothing will happen if the user plugs the dongle in before
plugging something into the dongle.
So, let's fix this by checking the sink count in both
nouveau_dp_probe_dpcd() and nouveau_dp_irq(), and reprobing the
connector if things change.

And of course, we'll also need to read the sink count from other drivers
as well if we're checking whether or not it's supported. So, let's

Since other drivers are also going to need to be aware of the sink count
in order to do proper dongle detection, we might as well steal i915's
DP_SINK_COUNT helpers and move them into DRM helpers so that other
dirvers can use them as well.
Note that this also starts using intel_dp_has_sink_count() in
intel_dp_detect_dpcd(), which is a functional change.

This adds support for querying the maximum clock rate of a downstream
port on a DisplayPort connection. Generally, downstream ports refer to
active dongles which can have their own pixel clock limits.
Note as well, we also start marking the connector as disconnected if we
can't read the DPCD, since we wouldn't be able to do anything without
DPCD access anyway.

We're going to be doing the same probing process in nouveau for
determining downstream DP port capabilities, so let's deduplicate the
work by moving i915's code for handling this into a shared helper:
drm_dp_read_downstream_info().
Note that when we do this, we also do make some functional changes while
we're at it:
* We always clear the downstream port info before trying to read it,
just to make things easier for the caller
* We skip reading downstream port info if the DPCD indicates that we
don't support downstream port info
* We only read as many bytes as needed for the reported number of
downstream ports, no sense in reading the whole thing every time
v2:
* Fixup logic for calculating the downstream port length to account for
the fact that downstream port caps can be either 1 byte or 4 bytes
long. We can actually skip fixing the max_clock/max_bpc helpers here
since they all check for DP_DETAILED_CAP_INFO_AVAILABLE anyway.
* Fix ret code check for drm_dp_dpcd_read
v5:
* Change name from drm_dp_downstream_read_info() to
drm_dp_read_downstream_info()
* Also, add "See Also" sections for the various downstream info
functions (drm_dp_read_downstream_info(), drm_dp_downstream_max_clock(),
drm_dp_downstream_max_bpc())

Currently we perform both short IRQ handling for DP, and connector
reprobing in the HPD IRQ handler. However since we need to grab
connection_mutex in order to reprobe a connector, in theory we could
accidentally block ourselves from handling any short IRQs until after a
modeset completes if a connector hotplug happens to occur in parallel
with a modeset.
I haven't seen this actually happen yet, but since we're cleaning up
nouveau's hotplug handling code anyway and we already have a hpd worker,
we can simply fix this by only relying on the HPD worker to actually
reprobe connectors when we receive a HPD IRQ. We also add a mask to
nouveau_drm to keep track of which connectors are waiting to be reprobed
in response to an HPD IRQ.

For whatever reason we currently unset the EDID for DP CEC support when
responding to the connector being unplugged, instead of just doing it in
nouveau_connector_detect() where we set the CEC EDID. This isn't really
needed and could even potentially cause us to forget to unset the EDID
if the connector is removed without a corresponding hpd event, so let's
fix that.

First some backstory here: Currently, we keep track of whether or not
we've enabled MST or not by trying to piggy-back off the MST helpers.
This means that in order to check whether MST is enabled or not, we
actually need to grab drm_dp_mst_topology_mgr.lock.
Back when I originally wrote this, I did this piggy-backing with the
intention that I'd eventually be teaching our MST helpers how to recover
when an MST device has stopped responding, which in turn would require
the MST helpers having a way of disabling MST independently of the
driver. Note that this was before I reworked locking in the MST helpers,
so at the time we were sticking random things under &mgr->lock - which
grabbing this lock was meant to protect against.
This never came to fruition because doing such a reset safely turned out
to be a lot more painful and impossible then it sounds, and also just
risks us working around issues with our MST handlers that should be
properly fixed instead. Even if it did though, simply calling
drm_dp_mst_topology_mgr_set_mst() from the MST helpers (with the
exception of when we're tearing down our MST managers, that's always OK)
wouldn't have been a bad idea, since drivers like nouveau and i915 need
to do their own book keeping immediately after disabling MST.
So-implementing that would likely require adding a hook for
helper-triggered MST disables anyway.
So, fast forward to now - we want to start adding support for all of the
miscellaneous bits of the DP protocol (for both SST and MST) we're
missing before moving on to supporting more complicated features like
supporting different BPP values on MST, DSC, etc. Since many of these
features only exist on SST and make use of DP HPD IRQs, we want to be
able to atomically check whether we're servicing an MST IRQ or SST IRQ
in nouveau_connector_hotplug(). Currently we literally don't do this at
all, and just handle any kind of possible DP IRQ we could get including
ESIs - even if MST isn't actually enabled.
This would be very complicated and difficult to fix if we need to hold
&mgr->lock while handling SST IRQs to ensure that the MST topology
state doesn't change under us. What we really want here is to do our own
tracking of whether MST is enabled or not, similar to drivers like i915,
and define our own locking order to decomplicate things and avoid
hitting locking issues in the future.
So, let's do this by refactoring our MST probing/enabling code to use
our own MST bookkeeping, along with adding a lock for protecting DP
state that needs to be checked outside of our connector probing
functions. While we're at it, we also remove a bunch of unneeded steps
we perform when probing/enabling MST:
* Enabling bits in MSTM_CTRL before calling drm_dp_mst_topology_mgr_set_mst().
I don't think these ever actually did anything, since the nvif methods
for enabling MST don't actually do anything DPCD related and merely
indicate to nvkm that we've turned on MST.
* Checking the MSTM_CTRL bit is intact when checking the state of an
enabled MST topology in nv50_mstm_detect(). I just added this to be safe
originally, but now that we try reading the DPCD when probing DP
connectors it shouldn't be needed as that will abort our hotplug probing
if the device was removed well before we start checking for MST..
* All of the duplicate DPCD version checks.
This leaves us with much nicer looking code, a much more sensible
locking scheme, and an easy way of checking whether MST is enabled or
not for handling DP HPD IRQs.
v2:
* Get rid of accidental newlines
v4:
* Fix uninitialized usage of mstm in nv50_mstm_detect() - thanks kernel

While the way we find the associated connector for an encoder is just
fine for legacy modesetting, it's not correct for nv50+ since that uses
atomic modesetting. For reference, see the drm_encoder kdocs.
Fix this by removing nouveau_encoder_connector_get(), and replacing it
with nv04_encoder_get_connector(), nv50_outp_get_old_connector(), and
nv50_outp_get_new_connector().
v2:
* Don't line-wrap for_each_(old|new)_connector_in_state in
nv50_outp_get_(old|new)_connector() - sravn
v3:
* Fix potential uninitialized usage of nv_connector (needs to be
initialized to NULL at the start). Thanks kernel test robot!
v4:
* Actually fix uninitialized nv_connector usage in
nv50_audio_component_get_eld(). The previous fix wouldn't have worked
since we would have started out with nv_connector == NULL, but
wouldn't clear it after a single drm_for_each_encoder() iteration.

Since commit fa3cdf8d0b09 ("drm/nouveau: Reset MST branching unit before

It's writing too much data. regmap_bulk_write expects number of
register sized chunks to write, not a byte sized length of the
bounce buffer. Bounce buffer needs to be padded too, so that
regmap_bulk_write will not read past the end of the buffer.

While reviewing a separate patch, I noticed that the formatting of the
commands, variables, and arguments was not in a monospaced font like the
rest of the Kbuild documentation (see kbuild/kconfig.rst for an
example). This is due to a lack of "::" before indented command blocks
and single backticks instead of double backticks for inline formatting.
Add those so that the document looks nicer in an HTML format, while not
ruining the look in plain text.
As a result of this, we can remove the escaped backslashes in the last
code block and move them to single backslashes.

First set of IIO fixes for the 5.9 cycle
Most of the fixes this time are for a long term issue that Lars-Peter
Clausen identified recently.
IIO assumes that any data pushed to the buffer interface (either kfifo
or another in kernel consumer) are naturally aligned. Unfortunately
this isn't true in a number of drivers, mostly by failing to ensure
the buffer used is aligned suitably for an s64 timestamp.
For the ones covered this time we use a structure to enforce this
alignment, with the added need for __aligned(8) to ensure 8 byte
alignment of the timestamp on x86_32 and similar platforms where
it would be 4 byte aligned giving different padded from some other
architectures.
Patches to make this requirement clearer and potentially cause an
error print will follow once we've cleaned up existing cases.
Note that it is a very hard to hit problem and as a result of this
as we only have one bug report despite the problem being present
for many years.
Other fixes:
* cros_ec:
- set gyroscope default frequency. For some older boards not having
this set can lead to a choice that doesn't work.
* counter,microchip-tcb-capture:
- Fix a wrong value check in error check.
* mcp3422
- Fix locking to protect against race condition.
* meson-adc

* rockchip-adc

The basic permission bits (protection bits in AmigaOS) have been broken
in Linux' AFFS - it would only set bits, but never delete them.
Also, contrary to the documentation, the Archived bit was not handled.
Let's fix this for good, and set the bits such that Linux and classic
AmigaOS can coexist in the most peaceful manner.
Also, update the documentation to represent the current state of things.

On the older-gen 32-bit SoCs the meson-saradc driver is used to read the
SoC temperature. This requires reading calibration data from the eFuse.
Looking up the calibration data nvmem-cell requires the OF device_node
pointer to be available in the struct device which is passed to
devm_nvmem_cell_get(). This however got lost with commit 8cb631ccbb1952
("iio: Remove superfluous of_node assignments") from indio_dev->dev. As
devm_nvmem_cell_get() is called in the initialization phase the
device_node is not yet available because the NVMEM cell is looked up
before iio_device_register() is called (which would then set the
device_node automatically).
Use the parent device to look up the NVMEM cell instead to fix this
issue.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart
from previous readings.
The explicit alignment of ts is necessary to ensure correct padding
on architectures where s64 is only 4 bytes aligned such as x86_32.

dev_pm_opp_remove_table() should drop a reference to the OPP table only
if the DT OPP table was parsed earlier with a call to
dev_pm_opp_of_add_table() earlier. Else it may end up dropping the
reference to the OPP table, which was added as a result of other calls
like dev_pm_opp_set_clkname(). And would hence result in undesirable
behavior later on when caller would try to free the resource again.

The Saitek X52 family of joysticks has a pair of axes that were
originally (by the Windows driver) used as mouse pointer controls. The
corresponding usage page is the Game Controls page, which is not
recognized by the generic HID driver, and therefore, both axes get
mapped to ABS_MISC. The quirk makes the second axis get mapped to
ABS_MISC+1, and therefore made available separately.
One Saitek X52 device is already fixed. This patch fixes the other two
