From the ChibiOS HAL I2C driver pages:
After a timeout the driver must be stopped and restarted because the bus is in
an uncertain state.
This commit does that stopping explicitly on any error that occurred, not only
timeouts. As all the i2c functions restart the peripheral if necessary it is
safe to do so.

* Use polled waiting on platforms that support it
Due to context switching overhead waiting a very short amount of time on
a sleeping thread is often not accurate and in fact not usable for timing
critical usage i.e. in a driver. Thus we use polled waiting for ranges
in the us range on platforms that support it instead. The fallback is
the thread sleeping mechanism.
This includes:
* ARM platforms with CYCCNT register (ARMv7, ARMv8) this is
incremented at CPU clock frequency
* GD32VF103 RISC-V port with CSR_MCYCLE register this is incremented at
CPU clock frequency
* RP2040 ARMv6 port which uses the integrated timer peripheral which is
incremented with a fixed 1MHz frequency
* Use wait_us() instead of chSysPolledDelayX
...as it is powered by busy waiting now.
* Add chibios waiting methods test bench
mpaland printf implementation was abandoned in ~2019 and the fork by
eyalroz is now regarded to be the goto replacement of it. So this commit
incoporates the changes needed to use this fork in QMK.

* chibios/timer: Move the 16-bit timer handling into a separate function
Extract the code which effectively makes a 32-bit tick counter from a
possibly 16-bit ChibiOS system timer into a separate function. Does
not really change the behavior of the timer API, but makes the actions
done in `timer_clear()` and `timer_read32()` more obvious.
* chibios/timer: Rename some variable to better reflect their role
* chibios/timer: Fix 32-bit tick counter overflow handling
The QMK timer API implementation for ChibiOS used a 32-bit tick counter
(obtained from the ChibiOS system timer) and then converted the value to
milliseconds to produce the timer value for QMK. However, the frequency
of the ChibiOS timer is above 1000 Hz in most cases (values of 10000 Hz
or even 100000 Hz are typically used), and therefore the 32-bit tick
counter was overflowing and wrapping around much earlier than expected
(after about 5 days for 10000 Hz, or about 12 hours for 100000 Hz).
When this wraparound happened, the QMK timer value was jumping back to
zero, which broke various code dealing with timers (e.g., deferred
executors).
Just making the tick counter 64-bit to avoid the overflow is not a good
solution, because the ChibiOS code which performs the conversion from
ticks to milliseconds may encounter overflows when handling a 64-bit
value. Adjusting just the value converted to milliseconds to account
for lost 2**32 ticks is also not possible, because 2**32 ticks may not
correspond to an integer number of milliseconds. Therefore the tick
counter overflow is handled as follows:
- A reasonably large number of ticks (the highest multiple of the
ChibiOS timer frequency that fits into uint32_t) is subtracted from
the tick counter, so that its value is again brought below 2**32.
The subtracted value is chosen so that it would correspond to an
integer number of seconds, therefore it could be converted to
milliseconds without any loss of precision.
- The equivalent number of milliseconds is then added to the converted
QMK timer value, so that the QMK timer continues to count
milliseconds as it was before the tick counter overflow.
* chibios/timer: Add a virtual timer to make 16-bit timer updates more reliable
The code which extends the 16-bit ChibiOS system timer to a 32-bit tick
counter requires that it is called at least once for every overflow of
the system timer (otherwise the tick counter can skip one or more
overflow periods). Normally this requirement is satisfied just from
various parts of QMK code reading the current timer value; however, in
some rare circumstances the QMK code may be blocked waiting for some
event, and when this situation is combined with having a rather high
timer frequency, this may result in improper timekeeping.
Enhance the timer reliability by adding a ChibiOS virtual timer which
invokes a callback every half of the timer overflow period. The virtual
timer callback can be invoked even when the normal QMK code is blocked;
the only requirement is that the timer interrupts are enabled, and the
ChibiOS kernel is not locked for an excessive time (but the timer update
will eventually work correctly if the virtual timer handling is not
delayed by more than a half of the timer overflow period).
Keeping a virtual timer always active also works around a ChibiOS bug
that can manifest with a 16-bit system timer and a relatively high timer
frequency: when all active virtual timers have delays longer than the
timer overflow period, the handling of virtual timers stops completely.
In QMK this bug can result in a `wait_ms()` call with a delay larger
than the timer overflow period just hanging indefinitely. However, when
the timer update code adds a virtual timer with a shorter delay, all
other virtual timers are also handled properly.

* [Core] Fix RISC-V toolchain installation
The risc-v toolchain is only available on distributions based on Debian 11+
so we check for their availability before installing them.
* [Core] Fix heap symbols and syscalls for picolibc
picolibc internally uses __heap_start and __heap_end instead of the
defacto chibios linker script standard __heap_base__ and __heap_end__
therefore we introduce these symbols as an alias. Usually all memory
used within QMK is statically allocated, but some algorithms make usage
of malloc and friends.
Also the timeval struct is not defined by picolibc for syscalls, therefore it
is declared as stub.

* adding uf2 flash support for blackpill 401
* forgot to add blackpill to keyboard header file
* making changes requested by drashna
* fixing tzarc s comments
* removing the keyboard
* undo the change to dactyl_manuform.h
* Make solo half of split keyboards (more) usable.
Using only one half of a split keyboard (that's using the split_common
framework to communicate) is not a great experience, since several read
timeouts per scan cycle cause an unusably slow scan rate.
This change blocks all split communication attempts for 500 ms
(configurable) after an error occurs, causing the scan rate to become at
least _more_ usable, but might need some tweaking to work fully on most
keyboards. One read timeout still needs to occur after the 500 ms has
passed, and if that timeout isn't low enough, some scan cycles may still
be too slow.
* Fix lint complaint.
* Require 25 consecutive comm errors to see comms as disconnected.
The number of max errors can be overridden by defining
`SPLIT_MAX_CONNECTION_ERRORS`.
* Add comments to new defines, and ability to disable disconnection check.
Also increase `SPLIT_MAX_CONNECTION_ERRORS` to 40, since it's divisible
by most relevant numbers for the description.
* Make lint happy ...again
* Only update `connection_check_timer` when needed.
* Add new defines to split keyboard documentation.
* Move connection timeout logic to transport.c, add `is_transport_connected`.
* Use split_common disconnection logic in matrix.c.
Instead of doing more or less the same thing twice.
* Move disconnection logic to `transport_master`.
Is a cleaner implementation, and causes the scan rate while disconnected
to increase instead of decrease.
* Lint fixes.
* Lower default `SERIAL_USART_TIMEOUT` to 20 ms.
The read timeout must be low enough to not cause exessively long scan
cycles when using a solo split half. 10 ms was determined from testing
to work fine even with the slowest defined baudrate of 19200 (5 ms was
too low for that case), so 20 ms should be fine for most cases.
* Remove `SERIAL_USART_TIMEOUT` from ergodox_infinity/config.h
Was somewhat mistakenly included in an earlier PR.
* Fix building with `USE_I2C`.
* Reduce built firmware size.
Not really sure why this works, the idea was taken from tzarc's work on
split disconnection.
* Tweak and improve opt-out for split disconnection logic.
There are now two ways to opt out from this feature:
* Set `SPLIT_MAX_CONNECTION_ERRORS` to 0. This will completely disable
the connection status checks (also affects the slave matrix reset logic in
matrix.c, though).
* Set `SPLIT_CONNECTION_CHECK_TIMEOUT` to 0. This will only disable the
communication throttling while disconnected. Will make the firmware
smaller.
* Make split disconnection logic work with custom transports.
Includes a fallback implementation for keyboards using a custom
split_util.c but not a custom matrix.c (currently no such keyboard seems
to be merged, though).
* Remove unnecessary include of timer.h

Now only affects Ergodox Infinity, Whitefox and K-type, though.
Switches over Ergodox Infinity to the `IC_TEENSY_3_1` board, since that

However, I would guess this issue is present for other K20x/Teensy 3.1
boards as well...

* Update ADC driver for STM32F1xx, STM32F3xx, STM32F4xx (#12403)
* Fix default ADC_RESOLUTION for ADCv3 (and ADCv4)
Recent ChibiOS update removed ADC_CFGR1_RES_10BIT from the ADCv3 headers
(that macro should not have been there, because ADCv3 has CFGR instead of
CFGR1). Fix the default value for ADC_RESOLUTION to use ADC_CFGR_RES_10BITS
if it is defined (that name is used for ADCv3 and ADCv4).
* Update ADC docs to match the actually used resolution
ADC driver for ChibiOS actually uses the 10-bit resolution by default
(probably to match AVR); fix the documentation accordingly. Also add
both ADC_CFGR_RES_10BITS and ADC_CFGR1_RES_10BIT constants (these names
differ according to the ADC implementation in the particular MCU).
* Fix pinToMux() for B12 and B13 on STM32F3xx
Testing on STM32F303CCT6 revealed that the ADC mux values for B12 and
B13 pins were wrong.
* Add support for all possible analog pins on STM32F1xx
Added ADC mux values for pins A0...A7, B0, B1, C0...C5 on STM32F1xx
(they are the same at least for STM32F103x8 and larger F103 devices, and
also F102, F105, F107 families). Actually tested on STM32F103C8T6
(therefore pins C0...C5 were not tested).
Pins F6...F10, which are present on STM32F103x[C-G] in 144-pin packages,
cannot be supported at the moment, because those pins are connected only
to ADC3, but the ChibiOS ADC driver for STM32F1xx supports only ADC1.
* Add support for all possible analog pins on STM32F4xx
Added ADC mux values for pins A0...A7, B0, B1, C0...C5 and optionally
F3...F10 (if STM32_ADC_USE_ADC3 is enabled). These mux values are
apparently the same for all F4xx devices, except some smaller devices may
not have ADC3.
Actually tested on STM32F401CCU6, STM32F401CEU6, STM32F411CEU6 (using
various WeAct “Blackpill” boards); only pins A0...A7, B0, B1 were tested.
Pins F3...F10 are inside `#if STM32_ADC_USE_ADC3` because some devices
which don't have ADC3 also don't have the GPIOF port, therefore the code
which refers to Fx pins does not compile.
* Fix STM32F3xx ADC mux table in documentation
The ADC driver documentation had some errors in the mux table for STM32F3xx.
Fix this table to match the datasheet and the actual code (mux settings for
B12 and B13 were also tested on a real STM32F303CCT6 chip).

I noticed this discrepancy (last row of the matrix treated differently than the

https://michael.stapelberg.ch/posts/2021-05-08-keyboard-input-latency-qmk-kinesis/
Before this commit, when tuning the delays I noticed ghost key presses when
pressing the F2 key, which is on the last row of the keyboard matrix: the
dead_grave key, which is on the first row of the keyboard matrix, would be
incorrectly detected as pressed.
After this commit, all keyboard matrix rows are interpreted correctly.
I suspect that my setup is more susceptible to this nuance than others because I
use GPIO_INPUT_PIN_DELAY=0 and hence don’t have another delay that might mask
the problem.
