* don't enable ipv6 by default due to privacy concerns
* move list of board support for ipv6 to socketpool documentation
* removed wifi.supports_ipvx properties
* throw an exception when start_dhcp_client(ipv6=True) but not supported
It is enabled on:
* SAMD51 boards with 1MB flash (SKU ending in 20A)
* Feather RP2040 DVI. Others have PIO usb host.
* All ESP32 boards.
* All nRF boards
Fixes#8676
Greedily grab as much RMT memory as we can. It blocks other RMT
transmit channels but we only use it temporarily anyway. The more
we can grab, the fewer interrupts are needed to keep the transmit
going.
Flickers may still happen due to file system writes but most of the
time the animation just pauses.
On ESP32, move CircuitPython to the second core. This helps NeoPixel
by moving the RMT interrupt to the second core as well.
When testing ESP32 I noticed that settings.toml writes won't apply
until after hard reset. This removes that constraint but still
requires the password to enable the web workflow.
Fixes#3835
I've identified that this is a bottleneck when I am
refining documentation; by returning a bare minimum of data
to allow the doc build to complete, I can do more builds in less time.
To use, `env NO_BINDINGS_MATRIX= make html`
This changes storage.mount() to require that a mount point exist
on the parent file system.
A bug in background tasks is also fixed where the function
parameter is cleared on pending callbacks during "reset".
Disk usage is shown on the directory listing and changes based on
the mounted file system. Writable is also loaded per-directory.
Fixes#8108. Fixes#8690. Fixes#8107.
Add `load_cert_chain`, `load_verify_locations`, `get_ciphers` and
`set_ciphers` SSLContext methods in ssl library, and update asyncio
`open_connection` and `start_server` methods with ssl support.

* Disable Nagle at the end of error messages so they are sent before
the socket is closed.
* Correctly discard file contents when the PUT file is too large.
* Correctly reset file size after failure to setting it too large.
* Change diskinfo.json to be list of disks in preparation of supporting
multiple disks.
* Bump version to 3 for the above change.
* Document diskinfo.json.
Fixes#8109
The behaviour described in the docs was not correct for either port.

If you have a variable frequency and pulse width, and you want to optimize
pulse resolution, then you must do a calculation beforehand to ensure you
normalize the array to keep all list values within bound. That calculation
requires RMT.source_freq(), RMT.clock_div(), and this 32767 constant.

To create an esp32.RMT() instance with an optimum (i.e. highest resolution)
clock_div is currently awkward because you need to know the source clock
frequency to calculate the best clock_div, but unfortunately that is only
currently available as an source_freq() method on the instance after you
have already created it. So RMT.source_freq() should really be a class
method, not an instance method. This change is backwards compatible for
existing code because you can still reference that function from an
instance, or now also, from the class.

This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings. At this stage only esp32 implements
this class, so the code for the bindings comes from that port.
The documentation is also updated to reflect the esp32's behaviour of
ADCBlock.connect().

This is just scaffolding for now, but the idea is that there should be an
addition to this file for every commit that uses the
`MICROPY_PREVIEW_VERSION_2` macro.
