Jonathan Hogg 21d0599bd1 esp32/modesp32: Add new gpio_deep_sleep_hold function.
Add a new function to control whether held pins will retain their function
through deep-sleep.

Also document this function and explain how to use this in quickref to
retain pin configuration during deep-sleep.

Damien George 106a83de22 esp32/esp32_partition: Add support for specifying block_size.
To support filesystems that use a block size different from the native
erase-page size.

Damien George a3bbd5332b esp32/machine_bitstream: Reinstate bitstream bit-bang implementation.
The bit-bang implementation was replaced with the RMT implementation in
599b61c086.  This commit brings back that
bit-bang code, and allows it to be selected via the new static method:

    esp32.RMT.bitstream_channel(None)

The bit-bang implementation may be useful if the RMT needs to be used for
something else, or if bit-banging is more stable in certain applications.

Jim Mussared c737cde947 docs: Replace ufoo with foo in all docs.
Anywhere a module is mentioned, use its "non-u" name for consistency.

The "import module" vs "import umodule" is something of a FAQ, and this
commit intends to help clear that up.  As a first approximation MicroPython
is Python, and so imports should work the same as Python and use the same
name, to a first approximation.  The u-version of a module is a detail that
can be learned later on, when the user wants to understand more and have
finer control over importing.

Existing Python code should just work, as much as it is possible to do that
within the constraints of embedded systems, and the MicroPython
documentation should match the idiomatic way to write Python code.

With universal weak links for modules (via MICROPY_MODULE_WEAK_LINKS) users
can consistently use "import foo" across all ports (with the exception of
the minimal ports).  And the ability to override/extend via "foo.py"
continues to work well.

Jonathan Hogg 0b3332c8e1 docs/library: Document new esp32.RMT features and fix wait_done.
Add new API for specifying the idle level and TX carrier output level, and
new write_pulses modes of operation.  Also fix wait_done documentation
which was inverted and wrong about timing.

Thorsten von Eicken c10d431819 esp32: Add basic support for Non-Volatile-Storage in esp32 module.
This commit implements basic NVS support for the esp32.  It follows the
pattern of the esp32.Partition class and exposes an NVS object per NVS
namespace.  The initial support provided is only for signed 32-bit integers
and binary blobs.  It's easy (albeit a bit tedious) to add support for
more types.

See discussions in: #4436, #4707, #6780

Zenix27 e76c7466b6 docs: Change `\*` to `*` in argument lists.
Latest versions of Sphinx (at least 3.1.0) do not need the `*` escaped and
will render the `\` in the output if it is there, so remove it.

Fixes issue #6209.

wait_done().

Jon Rob 1678f41744 esp32/esp32_rmt: Extend RMT to support carrier feature.
The ESP32 RMT peripheral has hardware support for a carrier frequency, and
this commit exposes it to Python with the keyword arguments carrier_freq
and carrier_duty_percent in the constructor.  Example usage:

    r = esp32.RMT(0, pin=Pin(2), clock_div=80, carrier_freq=38000, carrier_duty_percent=50)

David Lechner 1e6d18c915 docs: Fix Sphinx 3.x warnings, and enable warnings-as-errors on build.
This enables warnings as errors and fixes all current errors, namely:

- reference to terms in the glossary must now be explicit (:term:)
- method overloads must not be declared as a separate method or must
  use :noindex:
- 2 cases where `` should have been used instead of `

Thorsten von Eicken 952ff8a8ea esp32: Improve support for OTA updates.
This commit adds several small items to improve the support for OTA
updates on an esp32:

- a partition table for 4MB flash modules that has two OTA partitions ready
  to go to do updates
- a GENERIC_OTA board that uses that partition table and that enables
  automatic roll-back in the bootloader
- a new esp32.Partition.mark_app_valid_cancel_rollback() class-method to
  signal that the boot is successful and should not be rolled back at the
  next reset
- an automated test for doing an OTA update
- documentation updates

Thorsten von Eicken a177831c46 esp32/modesp32: Add idf_heap_info(capabilities) to esp32 module.
This commit adds an idf_heap_info(capabilities) method to the esp32 module
which returns info about the ESP-IDF heaps.  It's useful to get a bit of a
picture of what's going on when code fails because ESP-IDF can't allocate
memory anymore.  Includes documentation and a test.
