Avoid 8-bit timer overflows in debounce algorithms (#12240)
* 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

2021 May 29 Breaking Changes Update (#13034)

* docs(leader_key): infinite leader timeout docs

* Format code according to conventions (#12680)

* 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).

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.

* Fixup housekeeping from being invoked twice per loop. (#12933)

* 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.

- Bump Kinetis K20x to 64 bytes, too.
- Rollback Kinetis to 32 bytes as partitioning can only be done once. Add warning about changing the value.
- Change RAM-backed "fake" EEPROM implementations to match eeconfig's current usage.
- Add 24LC128 by request.

3542f594d9 Fix wake from suspend LED functionality
When waking from suspend, only enable the LED drivers if they were not previously set to disabled by the user. This functionality was removed by the recent updates to adapt Massdrop keyboards to QMK RGB Matrix. Affects Massdrop CTRL and ALT keyboards compiled using Massdrop Configurator mode.

763b26cdb9 RGB Matrix support for Massdrop CTRL/ALT (#5328)
* port Massdrop CTRL/ALT to use RGB Matrix

Co-authored-by: Matt Schneeberger <helluvamatt@gmail.com>

* Massdrop lighting support working

This commit is to get the Massdrop lighting code working again through use of the compilation define USE_MASSDROP_CONFIGURATOR added to a keymap's rules.mk.
Added keymaps for both CTRL and ALT named default_md and mac_md. These should be used if the Massdrop style lighting is desired.

* Updating config based on testing results with patrickmt & compile errors

* Updates for PR5328

For CTRL and ALT:
Moved location of new RGB Matrix macros from config_led.h to config.h.
Added RGB_MATRIX_LED_FLUSH_LIMIT (time between flushes) to config.h for correct LED driver update timing.
Re-added missing breathing code for when Massdrop configurator mode is defined.

* remove prilik keymap form PR

6e984a8b5e Update to arm_atsam wait and timer routines
Microsecond (us) delays are now handled by a busy wait loop according to MCU frequency. This replaces the system counter method which had an overhead of around 12us.
TC5 device and supporting routines removed as it was the old us delay counter.
wait_ms is now properly a macro to CLK_delay_ms.
wait_us is now properly a macro to CLK_delay_us.
Removed CLK_get_us as it has no use.
All calls to CLK_get_ms() have been replaced by timer_read64() with corrected typing.
All calls to CLK_delay_ms() have been replaced by wait_ms().
All calls to CLK_delay_us() have been replaced by wait_us() and timings verified or updated as needed after review on scope.
Corrected typing of variables using 64bit ms timer readings if needed.

ab91e07753 Massdrop keyboards console device support for hid_listen
Added hid_listen USB device for arm_atsam USB protocol.
Debug printing is now done through the console device (CONSOLE_ENABLE = yes) rather than the virtser device, for viewing in hid_listen.
Function dpf(...) renamed to CDC_printf(...) and should now be called directly if intending to print to the virtual serial device.
