a0cd18c1a5 stm32/boards/NUCLEO_H743ZI2: Add modified version of NUCLEO_H743ZI.
This commit creates a new stm32 board for the NUCLEO_H743ZI2, which is the
current version of this from ST.  This is a modified copy of the
NUCLEO_H743ZI board, and the ZI2 board differs in a few minor ways:

- LED2 has moved from PB7 to PE1 and is now yellow rather than blue
- the USB power enable has moved from PG6 to PG10
- the USER button is now pulled down

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

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 "-".

9d674cf7ab stm32/uart: Add support for LPUART1 on L0, L4, H7 and WB MCUs.
Add LPUART1 as a standard UART.  No low power features are supported, yet.
LPUART1 is enabled as the next available UART after the standard U(S)ARTs:

    STM32WB:      LPUART1 = UART(2)
    STM32L0:      LPUART1 = UART(6)
    STM32L4:      LPUART1 = UART(6)
    STM32H7:      LPUART1 = UART(9)

On all ports: LPUART1 = machine.UART('LP1')

LPUART1 is enabled by defining MICROPY_HW_LPUART1_TX and
MICROPY_HW_LPUART1_RX in mpconfigboard.h.

cc2a35b7b2 stm32/rtc: Validate the RTC prescaler on boot and change if incorrect.
Devices with RTC backup-batteries have been shown (very rarely) to have
incorrect RTC prescaler values.  Such incorrect values mean the RTC counts
fast or slow, and will be wrong forever if the power/backup-battery is
always present.

This commit detects such a state at start up (hard reset) and corrects it
by reconfiguring the RTC prescaler values.

0118c07916 stm32/machine_adc: Fix ADC auto-calibration to run when ADC not enabled.
Prior to this commit, the ADC calibration code was never executing because
ADVREGEN bit was set making the CR register always non-zero.

This commit changes the logic so that ADC calibration is always run when
the ADC is disabled and an ADC channel is initialised.  It also uses the LL
API functions to do the calibration, to make sure it is done correctly on
each MCU variant.

structure to fix this.
