20e7313453 samd/clock_config: Add HW_DFLL_USB_SYNC and HW_MCU_OSC32KULP extensions.
Two new compile flags are:

MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the
crystal.  It will synchronize the DFLL48M clock with the USB's SOF pulse.
If no USB is connected, it will fall back to open loop mode.  The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.

MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source.  Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal.  This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash.  Drawback: ticks_ms() and time.time() vs. than
ticks_us() and the peripherals like PWM run at not synchronous clocks.

- Remove all definitions that are included in the core feature level.
- Keep the default settings for feature level and float, to make the choice

a415752173 samd/machine_bitstream: Add the machine.bitstream() function.
The SAMD21 implementation is an adaption of @jimmo's code for STM32Lxx.
The only changes are the addresses and names of the port registers and the
timing parameters.

SAMD21: The precision is about +/-25ns at 48MHz clock frequency.  The first
two cycles are about 40-60 ns longer than set.  But still good enough to
drive a neopixel device.

SAMD51: The precision is about +/-30ns at 120MHz clock frequency.  Good
enough to drive a neopixel device.

channel is GPIO_no % 16.

- Use a short table for SAMD21.
- Add a comment to each line telling what it's for, making further use
  easier.
- Add preliminary handlers/entries for PendSV, EIC and Sercom.  These will
  be replaced later when the respecitve modules are added.

d693758ab2 samd/machine_pwm: Add the machine.PWM class.
Features are:
- 3 to 5 different frequency groups.
- Freq range of 1Hz - 24 MHz.
- Duty rate stays stable on freq change.

Keyword options to the PWM constructor:
- device=n Select a specific PWM device.  If no device is specified, a free
           device is chosen, if available at that pin.
- freq=nnnn
- duty_u16=nnnn
- duty_ns=nnnn
- invert=True/False Allowing two outputs on the same device/channel to have
                    complementary signals.

If both freq and duty are provided, PWM output will start immediately.

Pins at the same device have the same frequency.  If the PWM output number
exceeds the number of channels at the PWM device, the effctive channel_no
is output_no % channel_count.  So with a channel count of 4, output 7 is
assigned to channel 3.  Pins at a certain channel have the same frequency
and duty rate, but may be seperately inverted.

5c7e93ec48 samd/machine_adc: Add the machine.ADC class.
With the method read_u16().  Keyword arguments of the constructor are:
- bits=n    The resolution; default is 12.
- average=n The average of samples, which are taken and cumulated.  The
            default value is 16.  Averaging by hw is faster than averaging
            in code.

The ADC runs at a clock freq 1.5 MHz.  A single 12 bit conversion takes
8 microseconds.

6765d4bbd6 samd/pin_af: Add the pin af table and its helper functions.
The pin af table is a representation of the MUX table from the data sheet.
It provides information for each pin about the supported device functions.

That information is needed by pin.irq, machine.ADC, machine.PWM,
machine.UART, machine.SPI and machine.I2C.  For each of these, the table
tells for each pin, which device number, af number and pad number is
assigned.  Using the table gives a straight, uniform access to the
information, where the benefit outweights the size of the table, which is
not that large.

The tables are MCU-specific.  It is not required to tell for each board,
which and where each of the above devices is available.  That makes addding
boards easy.

Note: The information for DAC and I2S was not included, since it affects
only a few pins.

b4d29fd47a samd/clock_config: Set up the clock configuration.
Clock settings:
- GCLK0: 48 MHz (SAMD21) or 120 MHz(SAMD51).
- GCLK1: 32768 Hz for driving the PLL.
- GCLK2: 48 MHz for tzhe peripheral clock.
- GCLK3: 1 MHz (SAMD21) or 8 MHz (SAMD51) for the µs ticks timer.
- GCLK8: 1 kHz for WDT (SAMD21 only).

If a 32 kHz crystal is present, it will be used as clock source.  Otherwise
the DFLL48M in open-loop mode is used.

GCLK0 for SAM51 can be changed between 48 MHz and 200 MHz.  The specified

Damien George
8f4c108025 all: Remove MICROPY_PY_IO_FILEIO config option.
Since commit e65d1e69e8 there is no longer an
io.FileIO class, so this option is no longer needed.

This option also controlled whether or not files supported being opened in
binary mode (eg 'rb'), and could, if disabled, lead to confusion as to why
opening a file in binary mode silently did the wrong thing (it would just
open in text mode if MICROPY_PY_IO_FILEIO was disabled).

The various VFS implementations (POSIX, FAT, LFS) were the only places
where enabling this option made a difference, and in almost all cases where
one of these filesystems were enabled, MICROPY_PY_IO_FILEIO was also
enabled.  So it makes sense to just unconditionally enable this feature
(ability to open a file in binary mode) in all cases, and so just remove
this config option altogether.  That makes configuration simpler and means
binary file support always exists (and opening a file in binary mode is
arguably more fundamental than opening in text mode, so if anything should
be configurable then it should be the ability to open in text mode).

fbd47fc46c ports: Consolidate inclusion of umachine module in built-ins.
The inclusion of `umachine` in the list of built-in modules is now done
centrally in py/objmodule.c.  Enabling MICROPY_PY_MACHINE will include this
module.

As part of this, all ports now have `umachine` as the core module name
(previously some had only `machine` as the name).

then sys.path and sys.argv will be initialised and populated with default

710426024a all: Factor gchelper code to one place and use it for unix & ARM ports.
No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port.  This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.

Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.

The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.

This string is recognised by uncrustify, to disable formatting in the
region marked by these comments.  This is necessary in the qstrdef*.h files
to prevent modification of the strings within the Q(...).  In other places
it is used to prevent excessive reformatting that would make the code less
readable.
