format code according to conventions [skip ci]

* Fix extra keyboard report during test_fixture teardown

* Add tests for pressing two keys with only different modifers

* Fix #1708

When two keys that use the same keycode, but different modifiers were
pressed at the same time, the second keypress wasn't registered. This is
fixed by forcing a key release when we detect a new press for the same
keycode.

* Fix the NKRO version of is_key_pressed

* Fix uninitalized loop variable

+# QMK Breaking Change - 2020 Feb 29 Changelog
+
+Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
+
+
+## Update ChibiOS/ChibiOS-Contrib/uGFX submodules
+
+* General Notes
+    * A `make git-submodule` may be required after pulling the latest QMK firmware code to update affected submodules to the upgraded revisions
+    * Enabling link-time-optimization (`LINK_TIME_OPTIMIZATION_ENABLE = yes`) should work on a lot more boards
+* Upgrade to ChibiOS ver19.1.3
+    * This will allow QMK to update to upstream ChibiOS a lot easier -- the old version was ~2 years out of date. Automated update scripts have been made available to simplify future upgrades.
+    * Includes improved MCU support and bugfixes
+    * ChibiOS revision is now included in Command output
+    * Timers should now be more accurate
+* Upgrade to newer ChibiOS-Contrib
+    * Also includes improved MCU support and bugfixes
+    * ChibiOS-Contrib revision is now included in Command output
+* Upgrade to newer uGFX
+    * Required in order to support updated ChibiOS
+
+
+## Fix ChibiOS timer overflow for 16-bit SysTick devices
+
+* On 16-bit SysTick devices, the timer subsystem in QMK was incorrectly dealing with overflow.
+    * When running at a 100000 SysTick frequency (possible on 16-bit devices, but uncommon), this overflow would occur after 0.65 seconds.
+* Timers are now correctly handling this overflow case and timing should now be correct on ChibiOS/ARM.
+
+
+## Update LUFA submodule
+
+* Updates the LUFA submodule to include updates from upstream (abcminiuser/lufa)
+* Includes some cleanup for QMK DFU generation
+
+
+## Encoder flip
+
+* Flips the encoder direction so that `clockwise == true` is for actually turning the knob clockwise
+* Adds `ENCODER_DIRECTION_FLIP` define, so that reversing the expected dirction is simple for users.
+* Cleans up documentation page for encoders
+
+
+## Adding support for `BACKLIGHT_ON_STATE` for hardware PWM backlight
+
+* Previously, the define only affected software PWM, and hardware PWM always assumed an N-channel MOSFET.
+* The hardware PWM backlight setup has been updated to respect this option.
+* The default "on" state has been changed to `1` - **this impacts all keyboards using software PWM backlight that do not define it explicitly**. If your keyboard's backlight is acting strange, it may have a P-channel MOSFET, and will need to have `#define BACKLIGHT_ON_STATE 0` added to the keyboard-level `config.h`. Please see the PR for more detailed information.
+
+
+## Migrating `ACTION_LAYER_TAP_KEY()` entries in `fn_actions` to `LT()` keycodes
+
+* `fn_actions` is deprecated, and its functionality has been superseded by direct keycodes and `process_record_user()`
+* The end result of removing this obsolete feature should result in a decent reduction in firmware size and code complexity
+* All keymaps affected are recommended to switch away from `fn_actions` in favour of the [custom keycode](https://docs.qmk.fm/#/custom_quantum_functions) and [macro](https://docs.qmk.fm/#/feature_macros) features
+
+
+## Moving backlight keycode handling to `process_keycode/`
+
+* This refactors the backlight keycode logic to be clearer and more modular.
+* All backlight-related keycodes are now actioned in a single file.
+* The `ACTION_BACKLIGHT_*` macros have also been deleted. If you are still using these in a `fn_actions[]` block, please switch to using the backlight keycodes or functions directly.
+
+
+## Refactor Planck keymaps to use Layout Macros
+
+* Refactor Planck keymaps to use layout macros instead of raw matrix assignments
+* Makes keymaps revision-agnostic
+* Should reduce noise and errors in Travis CI logs
+
+
+## GON NerD codebase refactor
+
+* Splits the codebase for GON NerD 60 and NerdD TKL PCBs into two separate directories.
+* If your keymap is for a NerD 60 PCB, your `make` command is now `make gon/nerd60:<keymap>`.
+* If your keymap is for a NerD TKL PCB, your `make` command is now `make gon/nerdtkl:<keymap>`.

 ## What is QMK Firmware?
 
-QMK (*Quantum Mechanical Keyboard*) is an open source community that maintains QMK Firmware, QMK Toolbox, qmk.fm, and these docs. QMK Firmware is a keyboard firmware based on the [tmk\_keyboard](http://github.com/tmk/tmk_keyboard) with some useful features for Atmel AVR controllers, and more specifically, the [OLKB product line](http://olkb.com), the [ErgoDox EZ](http://www.ergodox-ez.com) keyboard, and the [Clueboard product line](http://clueboard.co/). It has also been ported to ARM chips using ChibiOS. You can use it to power your own hand-wired or custom keyboard PCB.
+QMK (*Quantum Mechanical Keyboard*) is an open source community centered around developing computer input devices. The community encompasses all sorts of input devices, such as keyboards, mice, and MIDI devices. A core group of collaborators maintains [QMK Firmware](https://github.com/qmk/qmk_firmware), [QMK Configurator](https://config.qmk.fm), [QMK Toolbox](https://github.com/qmk/qmk_toolbox), [qmk.fm](https://qmk.fm), and this documentation with the help of community members like you.
 
-## How to Get It
+## Get Started
 
-If you plan on contributing a keymap, keyboard, or features to QMK, the easiest thing to do is [fork the repo through Github](https://github.com/qmk/qmk_firmware#fork-destination-box), and clone your repo locally to make your changes, push them, then open a [Pull Request](https://github.com/qmk/qmk_firmware/pulls) from your fork.
+Totally new to QMK? There are two ways to get started:
 
-Otherwise, you can either download it directly ([zip](https://github.com/qmk/qmk_firmware/zipball/master), [tar](https://github.com/qmk/qmk_firmware/tarball/master)), or clone it via git (`git@github.com:qmk/qmk_firmware.git`), or https (`https://github.com/qmk/qmk_firmware.git`).
+* Basic: [QMK Configurator](https://config.qmk.fm)
+    * Just select your keyboard from the dropdown and program your keyboard.
+    * We have an [introductory video](https://www.youtube.com/watch?v=-imgglzDMdY) you can watch.
+    * There is also an overview [document you can read](newbs_building_firmware_configurator.md).
+* Advanced: [Use The Source](newbs.md)
+    * More powerful, but harder to use
 
-## How to Compile
+## Make It Yours
 
-Before you are able to compile, you'll need to [install an environment](getting_started_build_tools.md) for AVR or/and ARM development. Once that is complete, you'll use the `make` command to build a keyboard and keymap with the following notation:
+QMK has lots of [features](features.md) to explore, and a good deal of reference documentation to dig through. Most features are taken advantage of by modifying your [keymap](keymap.md), and changing the [keycodes](keycodes.md).
 
-    make planck/rev4:default
+## Need help?
 
-This would build the `rev4` revision of the `planck` with the `default` keymap. Not all keyboards have revisions (also called subprojects or folders), in which case, it can be omitted:
+Check out the [support page](support.md) to see how you can get help using QMK.
 
-    make preonic:default
+## Give Back
 
-## How to Customize
+There are a lot of ways you can contribute to the QMK Community. The easiest way to get started is to use it and spread the word to your friends.

+# ADC Driver
+
+QMK can leverage the Analog-to-Digital Converter (ADC) on supported MCUs to measure voltages on certain pins. This can be useful for implementing things such as battery level indicators for Bluetooth keyboards, or volume controls using a potentiometer, as opposed to a [rotary encoder](feature_encoders.md).
+
+This driver currently supports both AVR and a limited selection of ARM devices. On AVR devices, the values returned are 10-bit integers (0-1023) mapped between 0V and VCC (usually 5V or 3.3V). On supported ARM devices, there is more flexibility in control of operation through `#define`s, but by default the values returned are 12-bit integers (0-4095) mapped between 0V and VCC (usually 3.3V).
+
+## Usage
+
+To use this driver, add the following to your `rules.mk`:
+
+```make
+SRC += analog.c
+```
+
+Then place this include at the top of your code:
+
+```c
+#include "analog.h"
+```
+

+<sup>\* The ATmega328P possesses two extra ADC channels; however, they are not present on the DIP pinout, and are not shared with GPIO pins. You can use `adc_read()` directly to gain access to these.</sup>
+
+### ARM
+
+Note that some of these pins are doubled-up on ADCs with the same channel. This is because the pins can be used for either ADC.
+
+Also note that the F0 and F3 use different numbering schemes. The F0 has a single ADC and the channels are 0-based, whereas the F3 has 4 ADCs and the channels are 1 based. This is because the F0 uses the `ADCv1` implementation of the ADC, whereas the F3 uses the `ADCv3` implementation.

+|Function                    |Description                                                                                                        |
+|----------------------------|-------------------------------------------------------------------------------------------------------------------|
+|`analogReference(mode)`     |Sets the analog voltage reference source. Must be one of `ADC_REF_EXTERNAL`, `ADC_REF_POWER` or `ADC_REF_INTERNAL`.|
+|`analogRead(pin)`           |Reads the value from the specified Arduino pin, eg. `4` for ADC6 on the ATmega32U4.                                |
+|`analogReadPin(pin)`        |Reads the value from the specified QMK pin, eg. `F6` for ADC6 on the ATmega32U4.                                   |
+|`pinToMux(pin)`             |Translates a given QMK pin to a mux value. If an unsupported pin is given, returns the mux value for "0V (GND)".   |
+|`adc_read(mux)`             |Reads the value from the ADC according to the specified mux. See your MCU's datasheet for more information.        |
+
+### ARM
+
+Note that care was taken to match all of the functions used for AVR devices, however complications in the ARM platform prevent that from always being possible. For example, the `STM32` chips do not have assigned Arduino pins. We could use the default pin numbers, but those numbers change based on the package type of the device. For this reason, please specify your target pins with their identifiers (`A0`, `F3`, etc.). Also note that there are some variants of functions that accept the target ADC for the pin. Some pins can be used for multiple ADCs, and this specified can help you pick which ADC will be used to interact with that pin.
+
+|Function                    |Description                                                                                                         |
+|----------------------------|--------------------------------------------------------------------------------------------------------------------|
+|`analogReadPin(pin)`        |Reads the value from the specified QMK pin, eg. `A0` for channel 0 on the STM32F0 and ADC1 channel 1 on the STM32F3. Note that if a pin can be used for multiple ADCs, it will pick the lower numbered ADC for this function. eg. `C0` will be channel 6 of ADC 1 when it could be used for ADC 2 as well.|
+|`analogReadPinAdc(pin, adc)`|Reads the value from the specified QMK pin and ADC, eg. `C0, 1` will read from channel 6, ADC 2 instead of ADC 1. Note that the ADCs are 0-indexed for this function.|
+|`pinToMux(pin)`             |Translates a given QMK pin to a channel and ADC combination. If an unsupported pin is given, returns the mux value for "0V (GND)".|
+|`adc_read(mux)`             |Reads the value from the ADC according to the specified pin and adc combination. See your MCU's datasheet for more information.|
+
+## Configuration
+
+## ARM
+
+The ARM implementation of the ADC has a few additional options that you can override in your own keyboards and keymaps to change how it operates.
+
+|`#define`          |Type  |Default              |Description|
+|-------------------|------|---------------------|-----------|
+|ADC_CIRCULAR_BUFFER|`bool`|`false`              |If `TRUE`, then the implementation will use a circular buffer.|
+|ADC_NUM_CHANNELS   |`int` |`1`                  |Sets the number of channels that will be scanned as part of an ADC operation. The current implementation only supports `1`.|
+|ADC_BUFFER_DEPTH   |`int` |`2`                  |Sets the depth of each result. Since we are only getting a 12-bit result by default, we set this to `2` bytes so we can contain our one value. This could be set to 1 if you opt for a 8-bit or lower result.|
+|ADC_SAMPLING_RATE  |`int` |`ADC_SMPR_SMP_1P5`   |Sets the sampling rate of the ADC. By default, it is set to the fastest setting. Please consult the corresponding `hal_adc_lld.h` in ChibiOS for your specific microcontroller for further documentation on your available options.|
+|ADC_RESOLUTION     |`int` |`ADC_CFGR1_RES_12BIT`|The resolution of your result. We choose 12 bit by default, but you can opt for 12, 10, 8, or 6 bit. Please consult the corresponding `hal_adc_lld.h` in ChibiOS for your specific microcontroller for further documentation on your available options.|

+# QMK Compiler Development Guide
+
+This page attempts to introduce developers to the QMK Compiler. It does not go into nitty gritty details- for that you should read code. What this will give you is a framework to hang your understanding on as you read the code.
+
+# Overview
+
+The QMK Compile API consists of a few movings parts:
+
+![Architecture Diagram](https://raw.githubusercontent.com/qmk/qmk_api/master/docs/architecture.svg)
+
+API Clients interact exclusively with the API service. This is where they submit jobs, check status, and download results. The API service inserts compile jobs into [Redis Queue](https://python-rq.org) and checks both RQ and S3 for the results of those jobs.
+
+Workers fetch new compile jobs from RQ, compile them, and then upload the source and the binary to an S3 compatible storage engine.
+
+# Workers
+
+QMK Compiler Workers are responsible for doing the actual building. When a worker pulls a job from RQ it does several things to complete that job:
+
+* Make a fresh qmk_firmware checkout
+* Use the supplied layers and keyboard metadata to build a `keymap.c`
+* Build the firmware
+* Zip a copy of the source
+* Upload the firmware, source zip, and a metadata file to S3.
+* Report the status of the job to RQ
+
+# API Service
+
+The API service is a relatively simple Flask application. There are a few main views you should understand.
+
+## @app.route('/v1/compile', methods=['POST'])
+
+This is the main entrypoint for the API. A client's interaction starts here. The client POST's a JSON document describing their keyboard, and the API does some (very) basic validation of that JSON before submitting the compile job.
+
+## @app.route('/v1/compile/<string:job_id>', methods=['GET'])
+
+This is the most frequently called endpoint. It pulls the job details from redis, if they're still available, or the cached job details on S3 if they're not.
+
+## @app.route('/v1/compile/<string:job_id>/download', methods=['GET'])
+
+This method allows users to download the compiled firmware file.
+
+## @app.route('/v1/compile/<string:job_id>/source', methods=['GET'])
+
+This method allows users to download the source for their firmware.
