Jeff Epler aaca3eccf1 samd: PDMIn: Reduce code unrolling on samd21 only 
Instead of unrolling the code 16 times, unroll it 4 times and loop
over it 4 times.  This gives the same 16 iterations, but at an expense
of less flash space.

Save flash space 
* No weak link for modules. It only impacts _os and _time and is
  already disabled for non-full builds.
* Turn off PA00 and PA01 because they are the crystal on the Metro
  M0 Express.
* Change ejected default to false to move it to BSS. It is set on
  USB connection anyway.
* Set sinc_filter to const. Doesn't help flash but keeps it out of
  RAM.

Finer grained, per port tick locking 
Fixes #3504 hopefully.

This reflects our belief that the API is stable enough to avoid incompatible changes during 6.x.

Jeff Epler 27cbb690e5 _canio: Add listener matching 
Lightly tested:
 * no matches (catch-all)
 * standard address single address matches (even and odd positions)
 * standard address mask matches
 * only tested that extended doesn't match non-extended

Jeff Epler a2e1867f69 _canio: Minimal implementation for SAM E5x MCUs 
Tested & working:

 * Send standard packets
 * Receive standard packets (1 FIFO, no filter)

Interoperation between SAM E54 Xplained running this tree and
MicroPython running on STM32F405 Feather with an external
transceiver was also tested.

Many other aspects of a full implementation are not yet present,
such as error detection and recovery.

Jeff Epler 45eec5b5a5 samd: SPI: improve conditional code 
I recently misdiagnosed a "maybe-uninitialized" diagnostic as a bug in
asf4.  However, the problem was in our SPI code.

A special case for samr21 MCUs was being applied to same54p20a and possibly
other D5x/E5x MCUs, since the check was simply for pin PC19 existing at all.

Change the check to use the macro PIN_PC19F_SERCOM4_PAD0 which is only
defined if special function F of pin PC19 is SERCOM4 PAD0.

Reorganize the code a little bit so that brace-matching in editors is
not confused by the conditionalized code, including an unrelated change
for APA102_SCK's condition.

Revert the change to the Makefile that incorrectly attempted to silence
the diagnostic.

Jeff Epler c73182803d sdioio: fix code for the case where there is no SDHC1 
.. it doesn't really make a difference (the old code created an empty
else{} statement) but this is more correct.

This is compile-tested, and requires updates in the related submodules:

https://github.com/adafruit/samd-peripherals/pull/35
https://github.com/adafruit/asf4/pull/37

This should not be merged until those can also be merged.

Split pulseio.PWMOut into pwmio 
This gives us better granularity when implementing new ports because
PWMOut is commonly implemented before PulseIn and PulseOut.
