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. Signed-off-by: Damien George <damien@micropython.org>

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) Signed-off-by: Mike Teachman <mike.teachman@gmail.com>

rp2/machine_i2s: Deinit all active I2S instances on soft reset. Add `machine_i2s_deinit_all` to teardown any active I2S instances on soft reset. Prior to this fix, code using I2S required a try/finally in order to avoid a hard fault on soft reset. Fixes issue #14339. Signed-off-by: Phil Howard <phil@gadgetoid.com>

rp2/machine_pwm: Enable keyword args in constructor and add init method. This adds support for freq/duty_u16/duty_ns keyword arguments in the PWM constructor, and adds the PWM.init() method. Using init() without arguments enables a previously deinit-ed PWM again. Further changes in this commit: - Do not start PWM output if only duty was set. - Stop all PWM slices on soft-reset. - Fix a bug when changing the freq on a channel pair with duty_ns set.

rp2/machine_uart: Implement a Python UART IRQ handler. Supported trigger names: IRQ_RXIDLE, IRQ_TXIDLE, IRQ_BREAK - IRQ_RXIDLE: The handler for IRQ_RXIDLE is called reliably 31 UART bit times after the last incoming data. - IRQ_TXIDLE: This IRQ is triggered after at least >5 characters are sent at once. It is triggered when the TX FIFO falls below 4 elements. At that time, up to 5 bytes may still be in the FIFO and output shift register. - IRQ_BREAK: The IRQ triggers if a BREAK state is detected at RX. Properties & side effects: - After a BREAK, a valid character must be received before another break can be detected. - Each break puts a 0xff character into the input buffer. The irq.flags() value is cleared only with a new wanted event. Do not change the flags otherwise. Signed-off-by: robert-hh <robert@hammelrath.com>
