mimxrt: Add new, minimal port to NXP i.MX RT series CPUs. This is an extremely minimal port to the NXP i.MX RT, in the style of the SAMD port It's largely based on the TinyUSB mimxrt implementation, using the NXP SDK. It currently supports the Teensy 4.0 board with a REPL over the USB-VCP interface. This commit also adds the NXP SDK submodule (also from TinyUSB) to lib/nxp_driver. Note: if you already have the tinyusb submodule initialized recursively you will need to run the following as the tinyusb sub-submodules have been rearranged (upstream): git submodule deinit lib/tinyusb rm -rf .git/modules/lib/tinyusb git submodule update --init lib/tinyusb

Values outside of that range will be silently aligned. wdt.feed() Resets the watchdog timer (feeding). wdt.timeout_ms(value) Sets a new timeout and feeds the watchdog.

all: Remove third argument to MP_REGISTER_MODULE. It's no longer needed because this macro is now processed after preprocessing the source code via cpp (in the qstr extraction stage), which means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

It provides setting the date and time with rtc.init() or rtc.datetime(), and reading the date and time with rtc.datetime() or rtc.now(). The method weekday() reports the weekday of the current date. It starts with 0 for Monday. The tuple order for datetime() and now() matches the CPython sequence: (year, month, day, hour, minute, second, microsecond, TZ). TZ is ignored and reported as None. Microsecond is provided at a best effort. If a battery is not supplied, the default boot date/time is 1970/1/1 0:0:0. With a battery, the clock continues to run even when the board is not powered. The clock is quite precise. If not, using rtc.calibration() may help.

SDCard support is optional and requires `USDHC` peripheral. Thus this driver is not available on `MIMXRT1010_EVK`. SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1` in mpconfigboard.mk. Signed-off-by: Philipp Ebensberger

mimxrt: Support PWM using the FLEXPWM and QTMR modules. Frequency range 15Hz/18Hz to > 1 MHz, with decreasing resolution of the duty cycle. The basic API is supported as documentated, except that keyword parameters are accepted for both the instatiaton and the PWM.init() call. Extensions: support PWM for channel pairs. Channel pairs are declared by supplying 2-element tuples for the pins. The two channels of a pair must be the A/B channel of a FLEXPWM module. These form than a complementary pair. Additional supported keyword arguments: - center=value Defines the center position of a pulse within the pulse cycle. The align keyword is actually shortcut for center. - sync=True|False: If set to True, the channels will be synchronized to a submodule 0 channel, which has already to be enabled. - align=PWM.MIDDLE | PMW.BEGIN | PWM.END. It defines, whether synchronized channels are Center-Aligned or Edge-aligned. The channels must be either complementary a channel pair or a group of synchronized channels. It may as well be applied to a single channel, but withiout any benefit. - invert= 0..3. Controls ouput inversion of the pins. Bit 0 controls the first pin, bit 1 the second. - deadtime=time_ns time of complementary channels for delaying the rising slope. - xor=0|1|2 xor causes the output of channel A and B to be xored. If applied to a X channel, it shows the value oif A ^ B. If applied to an A or B channel, both channel show the xored signal for xor=1. For xor=2, the xored signal is split between channels A and B. See also the Reference Manual, chapter about double pulses. The behavior of xor=2 can also be achieved using the center method for locating a pulse within a clock period. The output is enabled for board pins only. CPU pins may still be used for FLEXPWM, e.g. as sync source, but the signal will not be routed to the output. That applies only to FLEXPWM pins. The use of QTMR pins which are not board pins will be rejected. As part of this commit, the _WFE() statement is removed from ticks_delay_us64() to prevent PWM glitching during calls to sleep().

mixmrt/machine_i2s: Add I2S protocol support. This commit adds support for machine.I2S on the mimxrt port. The I2S API is consistent with the existing stm32, esp32, and rp2 implementations. I2S features: - controller transmit and controller receive - 16-bit and 32-bit sample sizes - mono and stereo formats - sampling frequencies from 8kHz to 48kHz - 3 modes of operation: - blocking - non-blocking with callback - uasyncio - configurable internal buffer - optional MCK Tested with the following development boards: - MIMXRT1010_EVK, MIMXRT1015_EVK, MIMXRT1020_EVK, MIMXRT1050_EVK - Teensy 4.0, Teensy 4.1 - Olimex RT1010 - Seeed ARCH MIX Tested with the following I2S hardware peripherals: - UDA1334 - GY-SPH0645LM4H - WM8960 codec on board the MIMXRT boards and separate breakout board - INMP441 - PCM5102 - SGTL5000 on the Teensy audio shield Signed-off-by: Mike Teachman <mike.teachman@gmail.com>

mimxrt/machine_spi: Add the SPI class to the machine module. This class supports SPI bus controller mode, with blocking transfers. SPI device numbers start at 0, to comply with the pinout of the Teensy boards. With the configured clock frequency the fastest baud rate is 33MHz. For messages longer 16 bytes DMA is used. The class uses the existing framework with extmod/machine_spi.c. Extended driver options: - drive=n with n being between 1 and 6 or PIN.POWER_1 to PIN.POWER_6. Since the pins used by the SPI are fixed, no Pin settings can be made. Thus the drive option is added allowing to control ringing and crosstalk on the connection. - gap_ns=nnnnn is the time between sent data items in a frame given in ns. Default is 2 clock cycles.

mimxrt/machine_uart: Add the UART class to the machine module. The implementation uses the LPUARTx devices. Up to 8 UARTs can be used, given that the pins are accessible. E.g. 8 on Teensy 4.1, 5 on MIMXRT1020_EVK. For Tennsy 4.0 and 4.1 the UART numbers are as printed on the pinout 1..N. The MIMXRT10xx-EVK boards have only one UART named, which gets the number 1. All other UART are assigned to different Pins: MIMXRT1010-EVK: D0/D1 UART 1 D6/D7 UART 2 A0/D4 UART 3 MIMXRT1020-EVK: D0/D1 UART 1 D6/D9 UART 2 D10/D12 UART 3 D14/D15 UART 4 A0/A1 UART 5 MIMXRT1050-EVK, MIMXRT1060-EVK, MIMXRT1064-EVK: D0/D1 UART 1 D7/D6 UART 2 D8/D9 UART 3 A1/A0 UART 4

mimxrt/modmachine: Implement machine.WDT() and machine.reset_cause(). The API follows that of rp2, stm32, esp32, and the docs. wdt=machine.WDT(0, timeout) Timeout is given in ms. The valid range is 500 to 128000 (128 seconds) with 500 ms granularity. Values outside of that range will be silently aligned. wdt.feed() Resets the watchdog timer (feeding). wdt.timeout_ms(value) Sets a new timeout and feeds the watchdog. This is a new, preliminary method which is not yet documented. reset_cause = machine.reset_cause() Values returned: 1 Power On reset 3 Watchdog reset 5 Software reset: state after calling machine.reset() More elaborate API functions are supported by the MCU, like an interrupt called a certain time after feeding. But for port cosistency that is not implemented.

mimxrt: Add new, minimal port to NXP i.MX RT series CPUs. This is an extremely minimal port to the NXP i.MX RT, in the style of the SAMD port It's largely based on the TinyUSB mimxrt implementation, using the NXP SDK. It currently supports the Teensy 4.0 board with a REPL over the USB-VCP interface. This commit also adds the NXP SDK submodule (also from TinyUSB) to lib/nxp_driver. Note: if you already have the tinyusb submodule initialized recursively you will need to run the following as the tinyusb sub-submodules have been rearranged (upstream): git submodule deinit lib/tinyusb rm -rf .git/modules/lib/tinyusb git submodule update --init lib/tinyusb

all: Remove third argument to MP_REGISTER_MODULE. It's no longer needed because this macro is now processed after preprocessing the source code via cpp (in the qstr extraction stage), which means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.
