5954387858 drivers/onewire/ds18x20.py: Add support for DS1822 sensor.
DS1822P sensors behave just like the DS18B20 except for the following:
- it has a different family code: 0x22
- it has only the GND and DQ pins connected, it uses parasitic power from
  the data line

dc77fdb7d4 drivers/display/lcd160cr.py: In fast_spi, send command before flushing.
The intention of oflush() is to flush the "fast SPI" command itself so that
the SPI object is ready to use when the function returns.

1751f5ac7b drivers/sdcard: Do not release CS during the middle of read operations.
It seems that some cards do not tolerate releasing the card (by setting CS
high) after issuing CMD17 (and 18) and raising it again before reading
data. Somehow this causes the 0xfe data start marker not being read and
SDCard.readinto() is spinning forever (or until this byte is in the data).

This seems to fix weird behviour of SDCard.readblocks() returning different
data, also solved hanging os.mount() for my case with a 16GB Infineon card.

This stackexchange answer gives more context:

cc5a94044a drivers/memory/spiflash: Rename functions to indicate they use cache.
This patch renames the existing SPI flash API functions to reflect the fact
that the go through the cache:

    mp_spiflash_flush -> mp_spiflash_cache_flush
    mp_spiflash_read  -> mp_spiflash_cached_read
    mp_spiflash_write -> mp_spiflash_cached_write

86fe73beb9 drivers/memory/spiflash: Move cache buffer to user-provided config.
This patch removes the global cache variables from the SPI flash driver and
now requires the user to provide the cache memory themselves, via the SPI
flash configuration struct.  This allows to either have a shared cache for
multiple SPI flash devices (by sharing a mp_spiflash_cache_t struct), or
have a single cache per device (or a mix of these options).

To configure the cache use:

    mp_spiflash_cache_t spi_bdev_cache;

    const mp_spiflash_config_t spiflash_config =
        // any bus options
        .cache = &spi_bdev_cache,
    };

bdc875e602 drivers/memory/spiflash: Fix bugs in and clean up read/write functions.
mp_spiflash_read had a bug in it where "dest" and "addr" were incremented
twice for a certain special case.  This was fixed, which then allowed the
function to be simplified to reduce code size.

mp_spiflash_write had a bug in it where "src" was not incremented correctly
for the case where the data to be written included the caching buffer as
well as some bytes after this buffer.  This was fixed and the resulting
code simplified.

a739b35a96 drivers/memory/spiflash: Change to use low-level SPI object not uPy one.
This patch alters the SPI-flash memory driver so that it uses the new
low-level C SPI protocol (from drivers/bus/spi.h) instead of the uPy SPI
protocol (from extmod/machine_spi.h).  This allows the SPI-flash driver to
be used independently from the uPy runtime.

58ebeca6a9 drivers/bus: Pull out software SPI implementation to dedicated driver.
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c.  This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.

4e48700f9a drivers/memory/spiflash: Add support for QSPI interface.

either normal SPI or QSPI.  In both cases the bus can be implemented in
software or hardware, as long as the spiflash driver is passed the correct
configuration structure.

a275cb0f48 drivers/sdcard: Avoid allocation on the heap.
This commit fixes two things:
 1. Do not allocate on the heap in readblocks() - unless the block size
    is bigger than 512 bytes.
 2. Raise an error instead of returning 1 to indicate an error: the FAT
    block device layer does not check the return value. And other
    backends (e.g. esp32 blockdev) also raise an error instead of
    returning non-zero.

a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.

8fa03fee77 drivers/display/ssd1306.py: Improve performance of graphics methods.
It removes the need for a wrapper Python function to dispatch to the
framebuf method which makes each function call a bit faster, roughly 2.5x.
This patch also adds the rest of the framebuf methods to the SSD class.

    until we decide whether to add new utility functions.

299bc62586 all: Unify header guard usage.
The code conventions suggest using header guards, but do not define how
those should look like and instead point to existing files. However, not
all existing files follow the same scheme, sometimes omitting header guards
altogether, sometimes using non-standard names, making it easy to
accidentally pick a "wrong" example.

This commit ensures that all header files of the MicroPython project (that
were not simply copied from somewhere else) follow the same pattern, that
was already present in the majority of files, especially in the py folder.

The rules are as follows.

Naming convention:
* start with the words MICROPY_INCLUDED
* contain the full path to the file
* replace special characters with _

In addition, there are no empty lines before #ifndef, between #ifndef and
one empty line before #endif. #endif is followed by a comment containing
the name of the guard macro.

py/grammar.h cannot use header guards by design, since it has to be
included multiple times in a single C file. Several other files also do not
need header guards as they are only used internally and guaranteed to be
included only once:
* MICROPY_MPHALPORT_H
* mpconfigboard.h
* mpconfigport.h
* mpthreadport.h
* pin_defs_*.h
* qstrdefs*.h

683df1c8d5 drivers/onewire: Enable pull-up when init'ing the 1-wire pin.

a065d78675 drivers/onewire: Move onewire.py, ds18x20.py from esp8266 to drivers.
These drivers can now be used by any port (so long as that port has the
_onewire driver from extmod/modonewire.c).

These drivers replace the existing 1-wire and DS18X20 drivers in the
drivers/onewire directory.  The existing ones were pyboard-specific and
not very efficient nor minimal (although the 1-wire driver was written in
pure Python it only worked at large enough CPU frequency).

This commit brings backwards incompatible API changes to the existing
1-wire drivers.  User code should be converted to use the new drivers, or
check out the old version of the code and keep a local copy (it should
continue to work unchanged).
