This can be used to select the output buffer behaviour of the DAC. The
default values are chosen to retain backwards compatibility with existing
behaviour.
Thanks to @peterhinch for the initial idea to add this feature.
Reading into a bytearray will truncate values to 0xff so the assertions
checking read_timed() would previously always succeed.
Thanks to @peterhinch for finding this problem and providing the solution.
This event queue has UART events posted to it and they need to be drained
for it to operate without error. The queue is not used by the uPy UART
class so it should be removed to prevent the IDF emitting errors.
Fixes#3704.
Instead of emitnative.c having configuration code for each supported
architecture, and then compiling this file multiple times with different
macros defined, this patch adds a file per architecture with the necessary
code to configure the native emitter. These files then #include the
emitnative.c file.
This simplifies emitnative.c (which is already very large), and simplifies
the build system because emitnative.c no longer needs special handling for
compilation and qstr extraction.
Keeping all the stress related tests in one place makes it easier to
stress-test a given port, and to also not run such tests on ports that
can't handle them.
The 2nd and 3rd args of the ternary operator are treated like they are in
the same expression and must have similar types. void is not compatible
with int so that's why the compiler is complaining.
This patch moves the implementation of stream closure from a dedicated
method to the ioctl of the stream protocol, for each type that implements
closing. The benefits of this are:
1. Rounds out the stream ioctl function, which already includes flush,
seek and poll (among other things).
2. Makes calling mp_stream_close() on an object slightly more efficient
because it now no longer needs to lookup the close method and call it,
rather it just delegates straight to the ioctl function (if it exists).
3. Reduces code size and allows future types that implement the stream
protocol to be smaller because they don't need a dedicated close method.
Code size reduction is around 200 bytes smaller for x86 archs and around
30 bytes smaller for the bare-metal archs.
This caused a fatal compiler diagnostic after #750. This compiler
flag is already specified in the atmel-samd builds, so it makes
sense to do it here for the same reasons.

these are function prototypes not used in circuitpython. The
declarations began to conflict with ones in the upstream SDK
at some point, so delete them.
Recent vendor SDKs ship libs with code in .text section, which previously
was going into .irom0.text. Adjust the linker script to route these
sections back to iROM (follows upstream change).
