98d1c50159 esp32/network_wlan: Use esp_wifi_set/get_channel to config wifi channel.
Set the channel with esp_wifi_set_channel(), which adds support for setting
the channel of the STA interface

Get the channel with esp_wifi_get_channel() which returns the actual wifi
channel of the radio, rather than the configured channel.

fbe9417b90 extmod/ntptime: Factor out ntptime module from esp8266 port.
The ntptime module was previously only included in the ESP8266 port.  This
commit factors that module out into the extmod directory, makes it support
different epochs, and includes it in the rp2 port.

19f5da9e1b esp32/Makefile: Force micropython-lib as a required submodule.
Also use mkrules.mk's submodule target rather than duplicating the call to
`submodule sync`.

Until we can find a way to use idf.py/cmake to discover submodules we have
no way to discover optional or board-specific submodules so need to err on
the side of including everything.

f63b4f85aa py/parse: Work around xtensa esp-2020r3 compiler bug.
This commit works around a bug in xtensa-esp32-elf-gcc version esp-2020r3.

The bug is in generation of loop constructs.  The below code is generated
by the xtensa-esp32 compiler.  The first extract is the buggy machine code
and the second extract is the corrected machine code.  The test
`basics/logic_constfolding.py` fails with the first code and succeeds with
the second.

- the duplicate built-in "input" is removed from the esp32 port

665f0e2a68 esp32: Sleep one tick in MICROPY_EVENT_POLL_HOOK.
If MicroPython threads are enabled, loops waiting for an incoming event
should release the GIL and suspend, allowing other tasks to run while they
wait.

Prior to this commit, the problem can easily be observed by running a
thread that is both busy and regularly releases the GIL (for example a loop
doing something then sleeping a few ms after each iteration).  When the
main task is at the REPL, the thread is significantly stalled.  If the main
task is manually made to release the GIL (for example, by calling
utime.sleep_ms(500)) the other thread can be seen immediately working at
the expected speed again.

Additionally, there are various instances in where blocking functions run
MICROPY_EVENT_POLL_HOOK in a loop while they wait for a certain event/
condition.  For example the uselect methods poll objects to determine
whether data is available, but uses 100% of CPU while it does, constantly
calling MICROPY_EVENT_POLL_HOOK in the process.

The MICROPY_EVENT_POLL_HOOK macro is only ever used in waiting loops, where
(if threads are enabled) it makes sense to yield for a single tick so that
these loops do not consume all CPU cycles but instead other threads may
execute.  (In fact, the thing these loops wait for may even indirectly or
directly depend on another task being able to run.)

This change moves the sleep that was inside the REPL input function to
inside the MICROPY_EVENT_POLL_HOOK macro, where the GIL is already being
released, solving both the blocking REPL issue and the 100% CPU use issue
at the same time.

eae2e3516c esp32/main: Automatically size SPIRAM heap when allocated using malloc.
This change allows the same heap allocation rules to be used when using
malloc regardless if the board has SPRAM or normal RAM.

Integrating with the esp32-camera for example requires that ESP32 SPRAM be
allocatable using the esp-idf capabilities aware allocation functions.  In
the case of esp32-camera it's for the framebuffer.

Detect when CONFIG_SPIRAM_USE_MALLOC is in use and use the standard
automatic configuration of leaving 1/2 of the SPRAM available to other
FreeRTOS tasks.

This follows up on #5489, where we changed the esp32 core pinning to core 0
in order to work around an issue with IDF < 4.2.0.  Now that IDF > 4.2.0 is
available, we allow pinning back to core 1, which eliminates some
problematic callback latency with WiFi enabled.

NimBLE is also pinned to core 1 - the same core as MicroPython - when using
IDF >=4.2.

something else, or if bit-banging is more stable in certain applications.

e754c2e84f esp32/esp32_rmt: Install RMT driver on core 1.
MicroPython currently runs on core 0 of the esp32.  Calling
rmt_driver_install will mean that the RMT interrupt handler is also
serviced on core 0.  This can lead to glitches in the RMT output if
WiFi is enabled (for esp32.RMT and machine.bitstream).

This patch calls rmt_driver_install on core 1, ensuring that the RMT
interrupt handler is serviced on core 1.  This prevents glitches.

79ae7098ca esp32/machine_bitstream: Fix signal duplication on output pins.
After changing the bitstream implementation to use the RMT driver in
commit 72d86158121e32bbabaeade08f449d507bf40f9a
("esp32/machine_bitstream.c: Replace with RMT-based driver."), using
multiple `Neopixel` instances shows signal duplication between the
instances (i.e. a `write()` on one instance is written to all instances).

On invocation, the rmt driver configures the GPIO matrix to route the
output signal to the respective GPIO pin.  When called for a different
`NeoPixel` instance using a different pin, the new route is established,
but the old route still exists.  Now, the RMT output signal is sent to both
pins.

Fix this by setting the standard GPIO output function for the current pin
after uninstalling the RMT driver.
