Specifically, if you enable the shared endpoint for mouse reports (or keyboard, which force enables it for mouse), and you don't have mousekeys enabled, it does not properly enable shared mouse EP for pointing device (which uses mouse reports). This cause it to error out in compiling. This fixes up some of the logic to ensure that all use cases are supported, and consolidates some of the code.
* Support using a timer for wait_us() on ChibiOS-based boards (#12198)
There are spare GPT timers that can be used to get a more accurate
wait_ms() time. This is required for the matrix scan unselect delay (30µs)
to be shorter than the system tick rate of 100µs.
This is limited to the maximum GPT duration of 65535 so values above that
will automatically use the previous implementation based on the system
tick.
Using a specific timer means it can't be shared by another thread at the
same time so when wait_us() is called from anything other than the main
thread it will use the system tick implementation too.

* Add alternate ldscript for STM32duino (F103xB)
* Refactor out common ldscript stuff
* Move ldscripts into stm32duino board dir, add search path to ldflags
* Add HOLD_ON_OTHER_KEY_PRESS option for dual-role keys
Implement an additional option for dual-role keys which converts the
dual-role key press into a hold action immediately when another key is
pressed (this is different from the existing PERMISSIVE_HOLD option,
which selects the hold action when another key is tapped (pressed and
then released) while the dual-role key is pressed). The Mod-Tap keys
already behave in a similar way, unless the IGNORE_MOD_TAP_INTERRUPT
option is enabled (but with some additional delays); the added option
makes this behavior available for all other kinds of dual-role keys.
* [Docs] Update tap-hold docs for HOLD_ON_OTHER_KEY_PRESS
Document the newly added HOLD_ON_OTHER_KEY_PRESS option and update the
documentation for closely related options (PERMISSIVE_HOLD and
IGNORE_MOD_TAP_INTERRUPT).
Use Layer Tap instead of Mod Tap in examples for PERMISSIVE_HOLD and
HOLD_ON_OTHER_KEY_PRESS, because the effect of using these options with
Mod Tap keys is mostly invisible without IGNORE_MOD_TAP_INTERRUPT.
Add comments before return statements in sample implementations of
`get_ignore_mod_tap_interrupt()`, `get_hold_on_other_key_press()` and
`get_permissive_hold()`.
Thanks to @Erovia and @precondition for comments and suggestions to
improve the documentation.
* Combo processing improvements.
Now it is possible to use ModTap and LayerTap keys as part of combos.
Overlapping combos also don't trigger all the combos, just exactly the
one that you press.
New settings:
- COMBO_MUST_HOLD_MODS
- COMBO_MOD_TERM
- COMBO_TERM_PER_COMBO
- COMBO_MUST_HOLD_PER_COMBO
- COMBO_STRICT_TIMER
- COMBO_NO_TIMER
* Remove the size flags from combo_t struct boolean members.
This in the end actually saves space as the members are accessed so many
times. The amount of operations needed to access the bits uses more
memory than setting the size saves.
* Fix `process_combo_key_release` not called correctly with tap-only combos
* Fix not passing a pointer when NO_ACTION_TAPPING is defined.
* Docs for `COMBO_ONLY_FROM_LAYER`

* Add `EXTRA_SHORT_COMBOS` option.
Stuff combo's `disabled` and `active` flags into `state`. Possibly can
save some space.
* Add more examples and clarify things with dict management system.
- Simple examples now has a combo that has modifiers included.
- The slightly more advanced examples now are actually more advanced
instead of just `tap_code16(<modded-keycode>)`.
- Added a note that `COMBO_ACTION`s are not needed anymore as you can
just use custom keycodes.
- Added a note that the `g/keymap_combo.h` macros use the
`process_combo_event` function and that it is not usable in one's
keymap afterwards.

After a USB Reset event the device must, according to the spec wake up
from any suspend state, so the Configured event that arrives afterwards
should be interpreted as an implicit wakeup.
* Remove the #10088 hotfix for K20x MCU:s.
It seems to _cause_ the issue it intended to solve there.
* Cleaner way of removing #10088 hotfix.
Now only affects Ergodox Infinity, Whitefox and K-type, though.
Switches over Ergodox Infinity to the `IC_TEENSY_3_1` board, since that
was a nice place to implement the `restart_usb_driver` override.
However, I would guess this issue is present for other K20x/Teensy 3.1
boards as well...
* Fix comment regarding `IC_TEENSY_3_1` for all keyboards using it.
This prevents gcc from incorrectly trying to validate array bounds.
```
tmk_core/common/chibios/bootloader.c: error: '__builtin_memcpy' offset [0, 21] is out of the bounds [0, 0] [-Werror=array-bounds]
107 | __builtin_memcpy((void *) VBAT, (const void *)sys_reset_to_loader_magic, sizeof(sys_reset_to_loader_magic));

* Extensible split data sync capability through transactions.
- Split common transport has been split up between the transport layer
and data layer.
- Split "transactions" model used, with convergence between I2C and
serial data definitions.
- Slave matrix "generation count" is used to determine if the full slave
matrix needs to be retrieved.
- Encoders get the same "generation count" treatment.
- All other blocks of data are synchronised when a change is detected.
- All transmissions have a globally-configurable deadline before a
transmission is forced (`FORCED_SYNC_THROTTLE_MS`, default 100ms).
- Added atomicity for all core-synced data, preventing partial updates
- Added retries to AVR i2c_master's i2c_start, to minimise the number of
failed transactions when interrupts are disabled on the slave due to
atomicity checks.
- Some keyboards have had slight modifications made in order to ensure
that they still build due to firmware size restrictions.
* Fixup LED_MATRIX compile.
* Parameterise ERROR_DISCONNECT_COUNT.
* Intended usage is data validation in split transport code.
* Default space efficient algorithm.
* Opt-in fast table based algorithmn with #define CRC8_USE_TABLE switch.
* Define switches for size and speed optimized versions, the default is size
optimized by using uint_least8_t as datatype for calculations.
* #define CRC8_OPTIMIZE_SPEED uses uint_fast8_t as datatype for
calculations, this only affects 32-bit Archs like ARM and RISC-V.
* Placeholder crc_init() function for hardware backed crc calculation,
not implemented yet.
This commit makes atmel-dfu and chibios-dfu bootloaders retry to detect the bootloader
every 0,5 seconds (now configurable via the BOOTLOADER_RETRY_TIME makefile variable),
and a period is printed after every try. This is a much more pleasant behaviour than
the 5s retry timeout.
* Add fast_timer_t that is 16-bit or 32-bit based on architecture
A 16-bit timer will overflow sooner but be faster to compare on AVR.
* Avoid 8-bit timer overflows in debounce algorithms
Count down remaining elapsed time instead of trying to do 8-bit timer
comparisons.
Add a "none" implementation that is automatically used if DEBOUNCE is
0 otherwise it will break the _pk/_pr count down.
* Avoid unnecessary polling of the entire matrix in sym_eager_pk
The matrix only needs to be updated when a debounce timer expires.
* Avoid unnecessary polling of the entire matrix in sym_eager_pr
The matrix only needs to be updated when a debounce timer expires.
The use of the "needed_update" variable is trying to do what
"matrix_need_update" was added to fix but didn't work because it only
applied when all keys finished debouncing.
* Fix sym_defer_g timing inconsistency compared to other debounce algorithms
DEBOUNCE=5 should process the key after 5ms, not 6ms
* Add debounce tests
* add readPort() and some API to 'tmk_core/common/*/gpio.h'
The following macros have been added to gpio.h.
* readPort(port)
* setPortBitInput(port, bit)
* setPortBitInputHigh(port, bit)
* setPortBitOutput(port, bit)
* writePortBitLow(port, bit)
* writePortBitHigh(port, bit)
* add data type 'port_data_t' into gpio.h
* rename qmk_pin to pin
Debian bullseye (testing at the moment, but seems close to release) has
avr-libc 1:2.0.0+Atmel3.6.2-1.1 with some changes taken from the
Atmel-distributed toolchain. In particular, the <avr/io.h> header for
ATmega32A (avr/iom32a.h) now defines the FLASHEND constant as `0x7FFFU`,
and that `U` suffix breaks the firmware size check code, because the
shell arithmetic expansion that is used to calculate `MAX_SIZE` does not
support those C-specific suffixes.
As a workaround, add `-D__ASSEMBLER__` to the C preprocessor invocation
that is used to expand those macros; in this case avr/iom32a.h defines
`FLASHEND` without the `U` suffix, and everything works as it did before
with older avr-libc versions.
The exact same code is present in two places; they are both changed,
even though the code in `tmk_core/avr.mk` is actually never used for
ATmega32A (and the header for ATmega32U4 does not add that `U` suffix to
`FLASHEND` for some reason).

* 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).

* matrix: wait for row signal to go HIGH for every row (#12945)
I noticed this discrepancy (last row of the matrix treated differently than the
others) when optimizing the input latency of my keyboard controller, see also
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.

This converts the array that the Swap Hands feature uses to use PROGMEM,
and to read from that array, as such. Since this array never changes at
runtime, there is no reason to keep it in memory. Especially for AVR
boards, as memory is a precious resource.
When the USB device is connected, FreeBSD creates not one, but three
device nodes in /dev, e.g.: /dev/ttyU0, /dev/ttyU0.init, and
/dev/ttyU0.lock.
As a result, this leads to the USB variable containing 3 paths
(and therefore, whitespace) and messages like this one:
Device /dev/ttyU0
/dev/ttyU0.init
/dev/ttyU0.lock has appeared; assuming it is the controller.
This changes fixes the use of the -z flag of "[" (see test(1)). Also, it
removes undesired paths from the USB variable, leaving only
one path there (i.e., "/dev/ttyU0").
* Fix how USB queue overflow is handled in chibios.
This commit reverts PR 12472 (commit c823fe2d3f),
and it implements the original intent of the commit in a better way.
The original intent of the above mentioned commit was to not deadlock the
keyboard when console is enabled, and hid_listen is not started.
The above mentioned commit had a few drawbacks:
1) When a lot of data was printed to the console, the queue would get full,
and drop data, even if hid_listen was running. (For example having matrix debug
enabled just didn't work right at all)
2) I believe the function in which this was implemented is used by all other
USB endpoints, so with the above change, overflow, and data loss could
happen in other important functions of QMK as well.
This commit implements deadlock prevention in a slightly similar way to how
it's done on AVR. There is an additional static local variable, that memorizes
whether the console has timeouted before. If we are in the timeouted=false
state, then we send the character normally with a 5ms timeout. If it does
time out, then hid_listen is likely not running, and future characters should
not be sent with a timeout, but those characters should still be sent if there
is space in the queue. The difference between the AVR implementation and this
one is that the AVR implementation checks the queue state directly, but this
implementation instead attempts to write the character with a zero timeout.
If it fails, then we remain in the timeouted=true state, if it succeeds, then
hid_listen started removing data from the queue, so we can go out of the
timeouted=true state.
* Added comment explaining the timeouted logic to console flow control.
* Console flow control: refactor chibios flowcontrol code to make it more readable, and rename the timeouted variable to timed_out on both chibios and lufa. Changed comments to says timed_out is an approximation of listener_disconnected, to make it clear that it's not the same thing
* fix typo
Before this commit, attaching an ARM-based (i.e. ChibiOS-based) keyboard that
uses CONSOLE_ENABLE = yes and produces debug messages would deadlock the
keyboard unless one was running hid_listen.
With this commit, dead-locking writes to the queue are detected and prevented.
