dt-bindings: Validate DT binding schema in a single call

As the number of binding schemas has grown, the time to run
dt_binding_check has gotten pretty slow. A large part of this is due to
the slow startup time of Python (a well documented problem). There's not
currently any benefit to running dt-doc-validate one file at a time, so
let's switch it to run a single rule. Doing this means we loose the make
parallelism, but we can use xargs instead. This speeds up the validation
time from several minutes to <10 sec.

Since the validation is a single step with no output, we move running it
as part of the processed-schema-examples.json target. We also need to
reorder the extra-y entries so the validation is run first rather than
after all the examples are extracted.

Signed-off-by: Rob Herring <robh@kernel.org>

dt-bindings: Use json for processed-schema*

Change the format of processed-schema* from yaml to json to speed up
validation. With json output, using xargs and appending the output won't
work since json has explicit list begin and end characters. Instead,
we pass the schema files as a list in a temp file.

The parsing time for the processed schema goes down from ~2sec to 70ms.
Also, 'make dtbs_check' becomes 33% faster.

Some error messages are affected by this change. For example, "True was
expected" becomes "... is not of type 'boolean'". The order of messages
is also changed.

dt-bindings: Bump minimum version of dtschema to 2020.8.1

dtschema release 2020.8.1 gained several additions to help performance.
dt-doc-validate can now take a list of files and directories, and
dt-mk-schema can store the processed schema in JSON which is much faster
to parse than YAML. Utilizing both of these changes results in a 3-4x
speed improvement in running dt_binding_check.

of: platform: Destroy child devices symmetrically

Iterate over child devices in reverse when unpopulating a platform
device to make this step symmetrical with the population step. This
fixes an issue in the Tegra DRM driver where upon module unload the
DPAUX controller tries to unregister an I2C controller but will end
up waiting indefinitely because one of the SOR devices is keeping a
reference to it. Since the SOR devices are instantiated after the
DPAUX devices, they would only be removed (and hence release their
reference to the I2C controller) after the DPAUX devices have been
removed.

While destroying the child devices in reverse order helps in this
situation, it isn't fully safe to do so either. An even better way
would be for the child devices to be reordered to match the probe
order, which would work irrespective of the instantiation order.

However, reordering by probe order would be fairly complicated and
doesn't fix any known issues, so we'll go with the simpler fix for
now.

io_uring: short circuit -EAGAIN for blocking read attempt

One case was missed in the short IO retry handling, and that's hitting
-EAGAIN on a blocking attempt read (eg from io-wq context). This is a
problem on sockets that are marked as non-blocking when created, they
don't carry any REQ_F_NOWAIT information to help us terminate them
instead of perpetually retrying.

io_uring: sanitize double poll handling

There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.

Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().

Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.
