Deep Majumder c116fe1e18 Docs: Fixes link to I2C specification
The link to the I2C specification is broken. Although
"https://www.nxp.com" hosts Rev 7 (2021) of this specification, it is
behind a login-wall. Thus, an additional link has been added (which
doesn't require a login) and the NXP official docs link has been
updated.

  No regressions on our radar at this point. The igc problem fixed here

Linus Torvalds 93db8300f6 ARM: SoC fixes for v5.16, part 3
There are a number of DT fixes, mostly for mistakes found through
 static checking of the dts files again, as well as a couple of
 minor changes to address incorrect DT settings.
 
 For i.MX, there is yet another series of devitree changes to update
 RGMII delay settings for ethernet, which is an ongoing problem after
 some driver changes.
 
 For SoC specific device drivers, a number of smaller fixes came up:
 
  - i.MX SoC identification was incorrectly registered non-i.MX
    machines when the driver is built-in
 
  - One fix on imx8m-blk-ctrl driver to get i.MX8MM MIPI reset work
    properly
 
  - a few compile fixes for warnings that get in the way of -Werror
 
  - a string overflow in the scpi firmware driver
 
  - a boot failure with FORTIFY_SOURCE on Rockchips machines
 
  - broken error handling in the AMD TEE driver
 
  - a revert for a tegra reset driver commit that broke HDA

Robert Schlabbach 271225fd57 ixgbe: Document how to enable NBASE-T support
Commit a296d665ea ("ixgbe: Add ethtool support to enable 2.5 and 5.0
Gbps support") introduced suppression of the advertisement of NBASE-T
speeds by default, according to Todd Fujinaka to accommodate customers
with network switches which could not cope with advertised NBASE-T
speeds, as posted in the E1000-devel mailing list:

https://sourceforge.net/p/e1000/mailman/message/37106269/

However, the suppression was not documented at all, nor was how to
enable NBASE-T support.

Properly document the NBASE-T suppression and how to enable NBASE-T
support.

HP speaker amplifier initialization fixup to devices that are not already
known by passing "hda_model=alc285-hp-amp-init" to the

Linus Torvalds 5b46fb0383 sound fixes for 5.16-rc5
Another collection of small fixes.  It's still not quite calm yet,
 but nothing looks scary.
 
 ALSA core got a few fixes for covering the issues detected by fuzzer
 and the 32bit compat problem of control API, while the rest are all
 device-specific small fixes, including the continued fixes for Tegra.

Geert Uytterhoeven c4cb38b54b dt-bindings: input: gpio-keys: Fix interrupts in example
The "interrupts" property in the example looks weird:
  - The type is not in the last cell,
  - Level interrupts don't work well with gpio-keys, as they keep the
    interrupt asserted as long as the key is pressed, causing an
    interrupt storm.

Use a more realistic falling-edge interrupt instead.

This binding was already documented in phy.txt, commit 252ae5330d
("Documentation: devicetree: Add PHY no lane swap binding"), but got
accidently removed during YAML conversion in commit d8704342c1
("dt-bindings: net: Add a YAML schemas for the generic PHY options").

Note: 'enet-phy-lane-no-swap' and the absence of 'enet-phy-lane-swap' are
not identical, as the former one disable this feature, while the latter
one doesn't change anything.

Pull arm64 fixes from Will Deacon:
 "Three arm64 fixes for -rc4.

  One of them is just a trivial documentation fix, whereas the other two
  address a warning in the kexec code and a crash in ftrace on systems
  implementing BTI.

  The latter patch has a couple of ugly ifdefs which Mark plans to clean
  up separately, but as-is the patch is straightforward for backporting
  to stable kernels.

  Summary:

   - Add missing BTI landing instructions to the ftrace*_caller
     trampolines

   - Fix kexec() WARN when DEBUG_VIRTUAL is enabled

   - Fix PAC documentation by removing stale references to compiler
     flags"

Rob Herring b54472a02c dt-bindings: media: nxp,imx7-mipi-csi2: Drop bad if/then schema
The if/then schema for 'data-lanes' doesn't work as 'compatible' is at a
different level than 'data-lanes'. To make it work, the if/then schema
would have to be moved to the top level and then whole hierarchy of
nodes down to 'data-lanes' created. I don't think it is worth the
complexity to do that, so let's just drop it.

The error in this schema is masked by a fixup in the tools causing the
'allOf' to get overwritten. Removing the fixup as part of moving to
json-schema draft 2019-09 revealed the issue:

Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@30750000: ports:port@0:endpoint:data-lanes:0: [1] is too short
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml
Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.example.dt.yaml: mipi-csi@32e30000: ports:port@0:endpoint:data-lanes:0: [1, 2, 3, 4] is too long
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx7-mipi-csi2.yaml

The if condition was always true because 'compatible' did not exist in
'endpoint' node and a non-existent property is true for json-schema.

Sebastian Andrzej Siewior 6a631c0432 Documentation/locking/locktypes: Update migrate_disable() bits.
The initial implementation of migrate_disable() for mainline was a
wrapper around preempt_disable(). RT kernels substituted this with
a real migrate disable implementation.

Later on mainline gained true migrate disable support, but the
documentation was not updated.

Update the documentation, remove the claims about migrate_disable()
mapping to preempt_disable() on non-PREEMPT_RT kernels.

Akira Yokosawa 5c81691bb6 docs: admin-guide/blockdev: Remove digraph of node-states
While node-states-8.dot has two digraphs, the dot(1) command can
not properly handle multiple graphs in a DOT file and the
kernel-doc page at

    https://www.kernel.org/doc/html/latest/admin-guide/blockdev/drbd/figures.html

fails to render the graphs.

It turned out that the digraph of node_states can be removed.

Quote from Joel's reflection:

    On reflection, the digraph node_states can be removed entirely.
    It is too basic to contain any useful information. In addition
    it references "ioctl_set_state". The ioctl configuration
    interface for DRBD has long been removed. In fact, it was never
    in the upstream version of DRBD.

Remove node_states and rename the DOT file peer_states-8.dot.

As described at:
	https://stackoverflow.com/questions/23211695/modifying-content-width-of-the-sphinx-theme-read-the-docs

since Sphinx 1.8, the standard way to setup a custom theme is
to use html_css_files. While using html_context is OK with RTD
0.5.2, it doesn't work with 1.0.0, causing the theme to not load,
producing a very weird html.

Tested with:
	- Sphinx 1.7.9 + sphinx-rtd-theme 0.5.2
	- Sphinx 2.4.4 + sphinx-rtd-theme 0.5.2
	- Sphinx 2.4.4 + sphinx-rtd-theme 1.0.0

Takashi Iwai 9222ba68c3 Input: i8042 - add deferred probe support
We've got a bug report about the non-working keyboard on ASUS ZenBook
UX425UA.  It seems that the PS/2 device isn't ready immediately at
boot but takes some seconds to get ready.  Until now, the only
workaround is to defer the probe, but it's available only when the
driver is a module.  However, many distros, including openSUSE as in
the original report, build the PS/2 input drivers into kernel, hence
it won't work easily.

This patch adds the support for the deferred probe for i8042 stuff as
a workaround of the problem above.  When the deferred probe mode is
enabled and the device couldn't be probed, it'll be repeated with the
standard deferred probe mechanism.

The deferred probe mode is enabled either via the new option
i8042.probe_defer or via the quirk table entry.  As of this patch, the
quirk table contains only ASUS ZenBook UX425UA.

The deferred probe part is based on Fabio's initial work.
