iabdalkader 7649f5fbd2 stm32/sdram: Make SDRAM test cache aware, and optional failure with msg.
* Make SDRAM test cache-aware for newer MCUs.
* Use the defined data bus width (instead of the fixed 8-bits).
* Allow optional failure on error with verbose error messages.
* Test speed is now inverted (test accepts exhaustive instead fast).

Damien George 6214fa3f9e esp32/mphalport: Always yield at least once in delay_ms.
This helps the OS switch to and give other threads processing time during
the sleep.  It also ensures that pending events are handled, even when
sleeping for 0ms.

Fixes issue #5344.

Jonathan Hogg 8be29b9b1b esp32/machine_hw_spi: Use a 2 item SPI queue for long transfers.
Using a 2-item transaction queue instead of 1 allows long transfers to 
be executed with the minimum inter-transaction delay. Limit maximum 
transaction length to ensure an integer multiple of the SPI `bits` 
setting are transferred. Fixes #7511.

Julia 3966f67746 zephyr/machine_spi: Add support for hardware SPI.
Adds support for hardware SPI to the zephyr port.  Consistent with other
ports, such as rp2 and stm32, we only implement the SPI protocol functions
(init and transfer).  Explicit sck/mosi/miso selection is not supported
and new SPI instances are initialized with default values.

Mike Teachman 8a5bfe44a5 esp32,stm32: Add new machine.I2S class for I2S protocol support.
This commit adds I2S protocol support for the esp32 and stm32 ports, via
a new machine.I2S class.  It builds on the stm32 work of blmorris, #1361.

Features include:
- a consistent I2S API across the esp32 and stm32 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
- documentation for Pyboards and esp32-based boards
- tested on the following development boards:
  - Pyboard D SF2W
  - Pyboard V1.1
  - ESP32 with SPIRAM
  - ESP32

Damien George 86ef965352 stm32/adc: Simplify and generalise how pin_adcX table is defined.
The ADC_FIRST_GPIO_CHANNEL and ADC_LAST_GPIO_CHANNEL macros are no longer
needed.  Instead the pin_adcX table (X = 1, 2, 3) is now generated to be
the exact size needed for a given MCU, and MP_ARRAY_SIZE(pin_adcX) is used
to determine the upper bound.

This commit also allows CPU pins to be excluded from ADC configuration if
they are hidden by prefixing their name with a "-".

* For ADCAll (internal channels) ADC3 is used instead.

Jonathan Hogg 18e48a71ee esp32/esp32_rmt: Enhance RMT with idle_level and write_pulses modes.
This change allows specification of the idle level and TX carrier output
level (through changed initialisation API), and more flexible specification
of pulses for write_pulses.

This is a breaking change for the esp32.RMT constructor API.  Previous code
of this form:

    esp32.RMT(..., carrier_duty_percent=D, carrier_freq=F)

will now raise an exception and should be changed to:

    esp32.RMT(..., tx_carrier=(F, D, 1))

themselves, they might need specific DEBUG settings.

robert-hh f45412793e 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.
