Martin Fischer 5873390226 rp2/mphalport: Fix USB CDC RX handling to not block when unprocessed.
Prior to this commit, the USB CDC OUT endpoint got NACK'd if a character
was received but not consumed by the application, e.g. via
sys.stdin.read().  This meant that USB CDC was blocked and no additional
characters could be sent from the host.  In particular a ctrl-C could not
interrupt the application if another character was pending.

To fix the issue, the approach in this commit uses a callback tud_cdc_rx_cb
which is called by the TinyUSB stack on reception of new CDC data.  By
consuming the data immediately, the endpoint does not stall anymore.  The
previous handler tud_cdc_rx_wanted_cb was made obsolete and removed.

In addition some cleanup was done along the way: by adding interrupt_char.c
and removing the existing code mp_hal_set_interrupt_char().  Also, there is
now only one (stdin) ringbuffer.

Fixes issue #7996.

Mike Teachman b6dbbbe82f rp2/machine_i2s: Add I2S protocol support.
This commit adds I2S protocol support for the rp2 port:
- I2S API is consistent with STM32 and ESP32 ports
- I2S configurations supported:
  - master transmit and master receive
  - 16-bit and 32-bit sample sizes
  - mono and stereo formats
  - sampling frequency
  - 3 modes of operation:
    - blocking
    - non-blocking with callback
    - uasyncio
  - internal ring buffer size can be tuned
- DMA IRQs are managed on an I2S object basis, allowing other
  RP2 entities to use DMA IRQs when I2S is not being used
- MicroPython documentation
- tested on Raspberry Pi Pico development board
- build metric changes for this commit: text(+4552), data(0), bss(+8)

Damien George af64c2ddbd extmod/machine_pwm: Factor out machine.PWM bindings to common code.
This commit refactors machine.PWM and creates extmod/machine_pwm.c.  The
esp8266, esp32 and rp2 ports all use this and provide implementations of
the required PWM functionality.  This helps to reduce code duplication and
keep the same Python API across ports.

This commit does not make any functional changes.

Krzysztof Adamski 37d01d4be3 rp2/machine_rtc: Add initial support for RTC.
Initial support for machine.RTC on rp2 port. It only supports datetime()
method and nothing else. The method gets/returns a tuple of 8 items, just
like esp32 port, for example, but the usec parameter is ignored as the RP2
RTC only works up to seconds precision.

The Pico RTC isn't very useful as the time is lost during reset and there
seems to be no way to easily power up just the RTC clock with a low current
voltage, but still there seems to be use-cases for that, see issues #6831,
and a Thonny issue #1592. It was also requested for inclusion on v1.15
roadmap on #6832.

jahr 7ca686684e rp2: Add support for building different board configurations.
This change allows to build firmware for different rp2-based boards,
following how it is done in other ports like stm32 and esp32.  So far only
the original Pico and Adafruit Feather RP2040 are added.  Board names
should match (sans case) those in pico-sdk/src/boards/include/boards/.

Usage: Pico firmware can be build either using make as previously (it is
the default board) or by `make BOARD=PICO`.  Feather is built by `make
BOARD=ADAFRUIT_FEATHER_RP2040`.  Only the board name and flash drive size
is set, pin definition is taken from the appropriate pico-sdk board
definition.  Firmware is saved in the directory build-BOARD_NAME.

Phil Howard 0cf12dd59c rp2: Add support for USER_C_MODULES to CMake build system.
The parts that are generic are added to py/ so they can be used by other
ports that use CMake.

py/usermod.cmake:

* Creates a usermod target to hang user C/CXX modules from.
* Gathers sources from user C/CXX modules and libs for QSTR scan.

ports/rp2/CMakeLists.txt:

* Includes py/usermod.cmake.
* Links the resulting usermod library to the MicroPython target.

py/mkrules.cmake:

Add cxxflags to qstr.i.last custom command for CXX modules:

* MICROPY_CPP_FLAGS so CXX modules will find includes.
* -DNO_QSTR to fix fatal error missing "genhdr/qstrdefs.generated.h".

Usage:

The rp2 port can be linked against user C modules by running:

make USER_C_MODULES=/path/to/module/micropython.cmake

CMake will print a list of included modules.

Damien George 469345e728 rp2: Add new port to Raspberry Pi RP2 microcontroller.
This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040
microcontroller.

The build system uses pure cmake (with a small Makefile wrapper for
convenience).  The USB driver is TinyUSB, and there is a machine module
with most of the standard classes implemented.  Some examples are provided
in the examples/rp2/ directory.

Work done in collaboration with Graham Sanderson.
