e152d0c197 extmod/btstack: Schedule notify/indicate/write ops for bg completion.
The goal of this commit is to allow using ble.gatts_notify() at any time,
even if the stack is not ready to send the notification right now.  It also
addresses the same issue for ble.gatts_indicate() and ble.gattc_write()
(without response).  In addition this commit fixes the case where the
buffer passed to write-with-response wasn't copied, meaning it could be
modified by the caller, affecting the in-progress write.

The changes are:

- gatts_notify/indicate will now run in the background if the ACL buffer is
  currently full, meaning that notify/indicate can be called at any time.

- gattc_write(mode=0) (no response) will now allow for one outstanding
  write.

- gattc_write(mode=1) (with response) will now copy the buffer so that it
  can't be modified by the caller while the write is in progress.

All four paths also now track the buffer while the operation is in
progress, which prevents the GC free'ing the buffer while it's still
needed.

342800c9a2 travis: Change nrf pca10056 board to build with s140 SoftDevice.
It might compile fine with S132 as SoftDevice for nRF52840.
However, there might be different hardware on the SoC which in
turn could make it fail.

SoftDevice S140 is correct BLE stack for nRF52840 SoC and would
provide a more accurate test build.

15574cd665 nrf: Add support for time.ticks_xxx functions using RTC1.
This commit adds time.ticks_ms/us support using RTC1 as the timebase.  It
also adds the time.ticks_add/diff helper functions.  This feature can be
enabled using MICROPY_PY_TIME_TICKS.  If disabled the system uses the
legacy sleep methods and does not have any ticks functions.

In addition support for MICROPY_EVENT_POLL_HOOK was added to the
time.sleep_ms(x) function, making this function more power efficient and
allows support for select.poll/asyncio.  To support this, the RTC's CCR0
was used to schedule a ~1msec event to wakeup the CPU.

Some important notes about the RTC timebase:

- Since the granularity of RTC1's ticks are approx 30usec, time.ticks_us is
not perfect, does not have 1us resolution, but is otherwise quite usable.
For tighter measurments the ticker's 1MHz counter should be used.

- time.ticks_ms(x) should *not* be called in an IRQ with higher prio than
the RTC overflow irq (3).  If so it introduces a race condition and
possibly leads to wrong tick calculations.

See #6171 and #6202.

This reverts commit 4d6f60d428.

This implementation used the timeout as a maximum amount of time needed for
the operation, when actually the spec and other tools suggest that it's the
minumum delay needed between subsequent USB transfers.

494bcad8ab stm32/mboot: Disable polling mode by default and use IRQ mode instead.
Polling mode will cause failures with the mass-erase command due to USB
timeouts, because the USB IRQs are not being serviced.  Swiching from
polling to IRQ mode fixes this because the USB IRQs can be serviced between
page erases.

Note that when the flash is being programmed or erased the MCU is halted
and cannot respond to USB IRQs, because mboot runs from flash, as opposed
to the built-in bootloader which is in system ROM.  But the maximum delay
in responding to an IRQ is the time taken to erase a single page, about
100ms for large pages, and that is short enough that the USB does not
timeout on the host side.

Recent tests have shown that in the current mboot code IRQ mode is pretty
much the same speed as polling mode (within timing error), code size is
slightly reduced in IRQ mode, and IRQ mode idles at about half of the power
consumption as polling mode.

95ec0debec stm32/mboot: Remove the use of timeout in DFU_GETSTATUS.
This is treated more like a "delay before continuing" in the spec and
official tools and does not appear to be really needed.  In particular,
downloading firmware is much slower with non-zero timeouts because the host
must pause by the timeout between sending each DFU_GETSTATUS to poll for
download/erase complete.

332d83343f py: Rework mp_convert_member_lookup to properly handle built-ins.
This commit fixes lookups of class members to make it so that built-in
functions that are used as methods/functions of a class work correctly.

The mp_convert_member_lookup() function is pretty much completely changed
by this commit, but for the most part it's just reorganised and the
indenting changed.  The functional changes are:

- staticmethod and classmethod checks moved to later in the if-logic,
  because they are less common and so should be checked after the more
  common cases.

- The explicit mp_obj_is_type(member, &mp_type_type) check is removed
  because it's now subsumed by other, more general tests in this function.

- MP_TYPE_FLAG_BINDS_SELF and MP_TYPE_FLAG_BUILTIN_FUN type flags added to
  make the checks in this function much simpler (now they just test this
  bit in type->flags).

- An extra check is made for mp_obj_is_instance_type(type) to fix lookup of
  built-in functions.

Fixes #1326 and #6198.

f84145bea1 zephyr: Implement machine.Pin.irq() for setting callbacks on pin change.
Supports hard and soft interrupts.  In the current implementation, soft
interrupt callbacks will only be called when the VM is executing, ie they
will not be called during a blocking kernel call like k_msleep.  And the
behaviour of hard interrupt callbacks will depend on the underlying device,
as well as the amount of ISR stack space.

Soft and hard interrupts tested on frdm_k64f and nucleo_f767zi boards.

8bbaa20227 stm32/mboot: Implement DFU mass erase.
The implementation internally uses sector erase to wipe everything except
the sector(s) that mboot lives in (by erasing starting from
APPLICATION_ADDR).

The erase command can take some time (eg an STM32F765 with 2MB of flash
takes 8 to 10 seconds).  This time is normally enough to make pydfu.py fail
with a timeout.  The DFU standard includes a mechanism for the DFU device
to request a longer timeout as part of the get-status response just before
starting an operation.  This timeout functionality has been implemented
here.

e4fcd216e0 stm32/usbd_cdc_interface: Remove full==size-1 limitation on tx ringbuf.
Before this commit the USB VCP TX ring-buffer used the basic implementation
where it can only be filled to a maximum of buffer size-1.  For a 1024 size
buffer this means the largest packet that can be sent is 1023.  Once a
packet of this size is sent the next byte copied in goes to the final byte
in the buffer, so must be sent as a 1 byte packet before the read pointer
can be wrapped around to the beginning.  So in large streaming transfers,
watching the USB sniffer you basically get alternating 1023 byte packets
then 1 byte packets.

This commit changes the ring-buffer implementation to a scheme that doesn't
have the full-size limitation, and the USB VCP driver can now achieve a
constant stream of full-sized packets.  This scheme introduces a
restriction on the size of the buffer: it must be a power of 2, and the
maximum size is half of the size of the index (in this case the index is
16-bit, so the maximum size would be 32767 bytes rounded to 16384 for a
power-of-2).  But this is not a big limitation because the size of the
ring-buffer prior to this commit was restricted to powers of 2 because it
was using a mask-based method to wrap the indices.

For an explanation of the new scheme see
https://www.snellman.net/blog/archive/2016-12-13-ring-buffers/

The RX buffer could likely do with a similar change, though as it's not
read from in chunks like the TX buffer it doesn't present the same issue,
all that's lost is one byte capacity of the buffer.

USB VCP TX throughput is improved by this change, potentially doubling the
speed in certain cases.
