* resolve race condition between suspend and wake in LUFA
* avoid multiple calls to suspend_power_down() / suspend_wakeup_init()
* Remove duplicate suspend_power_down_kb() call

* speculative chibios version of pause-after-wake
* make wakeup delay configurable, and adjust value
* better location for wakeup delay
* Add support for 8 buttons to mouse report
This includes support for 8 buttons in mousekeys. However, this does move the keys around due to the fact that the last mousekey keycode is already 0xFF, so any past that would not work with register_code and the like, breaking them for tap hold keys, encoders, and other features.

* Update ADB impelmentation in tmk_core to recent version.
Pcked from tmk_keyboard repository revision: 48d696443857512d45f9a7329e0dd0a76345860f
* Restore convenient ADB functions used in QMK port.
* Do cformat.
* Split dmac_desc declaration and definition
According to the official documentation[1] gcc 10 is more strict about
correct extern usage.
I've had to move the definition of dmac_desc and dmac_desc_wb from
i2c_master.h to the corresponding .c file. This could be an issue if
anyone includes the i2c_master.h file without liking with the object
file.
[1]: https://gcc.gnu.org/gcc-10/porting_to.html
* Remove the keymap_config definition from keymaps
The keymap_config def was conflicting with the one found in
tmk_core/common/magic.c. Declaring it extern in magic.c breaks a bunch
of keyboard that rely on that declaration (like the ergodox). Instead
I've removed the one found in the keymap.c of the massdrop alt.
The same change will have to be made to other keyboards.
- Set all other ChibiOS defaults to 'off', when not targeting Proton-C
- Modified all existing F303 boards to point at the QMK_PROTON_C to ensure repeatable binary output
- Modified version.h generation so that SKIP_VERSION=yes generates the same output

The `KEYBOARD_SHARED_EP=yes` option was breaking the VIA support,
because the raw HID interface number in this case was 0 instead of 1,
and the VIA app depends on the exact interface number for raw HID.
Change the interface ordering to put the shared interface before the raw
HID interface if `KEYBOARD_SHARED_EP` is enabled, so that the raw HID
interface can keep its number.

* Update vusb to match 3rd endpoint.
- With the addition of https://github.com/qmk/v-usb/pull/1 a 3rd endpoint (endpoint4) becomes available.
- We can assign mouse/extrakeys to that endpoint as its a desirable feature and leave rawhid and console to compete for the 2nd endpoint.
NOTE: The version of vusb.c in future branch is older than master. Just remember that it will need a #error if both raw_hid and console are enabled at the same time.

* Updated vusb submodule to latest commit
* Add `st-flash` flash target
Add support for flashing the firmware via the `st-flash` utility from
the STLink Tools package (https://github.com/stlink-org/stlink).
* Add `st-flash` to the `qmk flash -b` output
* Initialize Layer State on startup
Right now, on startup, the default layer state gets called and set, triggering the callback functions for the default layer state. However, the normal layer state never actually gets initialized. It's set to 0 directly, by default, but the callback functions are never actually called. This creates some inconsistency in the behavior for end users. This adds a simple "clear" that triggers the callback on startup. This should produce more consisten behavior between the two functions and layer masks.
* Stupid hack
* Fix type casting?
* Fix compile issues with magic is disabled
* add support for hid gamepad interface
add documentation for HID joystick
Add joystick_task to read analog axes values even when no key is pressed or release. update doc
Update docs/feature_joystick.md
Manage pin setup and read to maintain matrix scan after analog read
* Incorporates patches and changes to HID reporting
There are some patches provided by @a-chol incorporated on this commit,
and also some changes I made to the HID Report structure.
The most interesting is the one dealing with number of buttons: Linux
doesn't seem to care, but Windows requires the HID structure to be byte
aligned (that's in the spec). So if one declares 8/16/32... buttons they
should not have any issues, but this is what happens when you have 9
buttons:
```
bits |0|1|2|3|4|5|6|7|
|*|*|*|*|*|*|*|*| axis 0 (report size 8)
|*|*|*|*|*|*|*|*| ...
|*|*|*|*|*|*|*|*|
|*|*|*|*|*|*|*|*|
|*|*|*|*|*|*|*|*|
|*|*|*|*|*|*|*|*|
|*|*|*|*|*|*|*|*| axis 6
|*|*|*|*|*|*|*|*| first 8 buttons (report size 1)
|*| | | | | | | | last of 9 buttons, not aligned
```
So for that I added a conditonal that will add a number of reports with
size 1 to make sure it aligns to the next multiple of 8. Those reports
send dummy inputs that don't do anything aside from aligning the data.
Tested on Linux, Windows 10 and Street Fighter (where the joystick is
recognized as direct-input)
* Add save and restore of each pin used in reading joystick (AVR).
Allow output pin to be JS_VIRTUAL_AXIS if the axis is connected to Vcc
instead of an output pin from the MCU.
Fix joystick report id
Fix broken v-usb hid joystick interface. Make it more resilient to unusual settings (none multiple of eight button count, 0 buttons or 0 axes)
Correct adc reading for multiple axes. Piecewise range conversion for uncentered raw value range. Input, output and ground pin configuration per axis.

* Re-fix the dual-bank bootloader stuff.
* Use wait_ms() instead of using nop's for a delay, as ChibiOS is actually running at the time of bootloader jump.
Mousekey scrolling should have a separate repeat variable
to keep track of scrolling acceleration, instead of being
tied to mouse movement scolling in mousekeys. The send function
should record when the last movement was made since this is
when movement is actually sent. Doing this fixes the bug where
the initial press of a mousekey scroll button causes a double scroll.

Process mouse movement in the keymap before it is sent to the host. Example uses
include filtering noise, adding acceleration, and automatically activating a
layer. To use, define the following function in your keymap:
void ps2_mouse_moved_user(report_mouse_t *mouse_report);
With this change, when ps2_mouse is disabled, mousekeys works as usual. With
ps2_mouse enabled, mousekeys button state is shared with ps2_mouse for clicking,
dragging, and scrolling, mousekeys clicks are produced by ps2_mouse only, and
mouskeys button state is transferred to mousekeys without generating clicks to
enable mousekeys dragging.

This commits add the SH_OS keycode, which works similarly to one shot
layers:
* while pressed, the keyboard is swapped
* if no keys were pressed while it was pressed, the next key press is
swapped
SH_OS also supports chaining with one shot layers:
OSL(x) + SH_OS + key interprets the key press on the oneshot layer.
The ONESHOT_TIMEOUT setting used by one shot keys and layers is also
used by oneshot swap hands. In the above chaining scenario the timeout
of the oneshot layer is reset when swap hands is activated.

* tmk_core/common: Fixing TIMER_DIFF macro to calculate difference correctly after the timer wraps.
Let's go through an example, using the following macro:
If the first timer read is 0xe4 and the second one is 0x32, the timer wrapped.
If the timer would have had more bits, it's new value would have been 0x132,
and the correct difference in time is 0x132 - 0xe4 = 0x4e
old code TIMER_DIFF_8(0x32, 0xe4) = 0xff - 0xe4 + 0x32 = 0x4d, which is wrong.
new code TIMER_DIFF_8(0x32, 0xe4) = 0xff + 1 - 0xe4 + 0x32 = 0x4e, which is correct.
This also gives a chance for a smart compiler to optimize the code using normal
integer overflow.
For example on AVR, the following C code:
uint8_t __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer)
{
return TIMER_DIFF_8(current_timer, start_timer);
}
With the original code, it gets translated to the following list of instructions:
00004c6e <test>:
4c6e: 98 2f mov r25, r24
4c70: 86 1b sub r24, r22
4c72: 96 17 cp r25, r22
4c74: 08 f4 brcc .+2 ; 0x4c78 <test+0xa>
4c76: 81 50 subi r24, 0x01 ; 1
4c78: 08 95 ret
But with this commit, it gets translated to a single instruction:
00004c40 <test>:
4c40: 86 1b sub r24, r22
4c42: 08 95 ret
This unfortunately doesn't always work so nicely, for example the following C code:
int __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer)
{
return TIMER_DIFF_8(current_timer, start_timer);
}
(Note: return type changed to int)
With the original code it gets translated to:
00004c6e <test>:
4c6e: 28 2f mov r18, r24
4c70: 30 e0 ldi r19, 0x00 ; 0
4c72: 46 2f mov r20, r22
4c74: 50 e0 ldi r21, 0x00 ; 0

There is not much performance improvement in this case, however at least with this
commit it functions correctly.
Note: The following commit will improve compiler output for the latter example.
* tmk_core/common: Improve code generation for TIMER_DIFF* macros
Because of integer promotion the compiler is having a hard time generating
efficient code to calculate TIMER_DIFF* macros in some situations.
In the below example, the return value is "int", and this is causing the
trouble.
Example C code:
int __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer)
{
return TIMER_DIFF_8(current_timer, start_timer);
}

Note: the example is showing -Os but improvements can be seen at all optimization levels,
including -O0. We never use -O0, but I tested it to make sure that no extra code is
generated in that case.OA
* quantum/debounce: Fix custom wrapping timers in eager_pr and eager_pk debounce algorithms
Please see the below simulated sequence of events:
Column A is the 16-bit value returned by read_timer();
Column B is the value returned by custom_wrap_timer_read();
Column C is the original code: (timer_read() % MAX_DEBOUNCE)

read_timer() wraps about every 1.09 seconds, and so debouncing might
fail at these times without this commit.
* quantum/debounce/eager_pr and eager_pk: modifications for code readability according to code review.
* quantum/debounce/eager_pr and eager_pk: modifications for code readability according to code review. (2)
* Add PS2_MOUSE_ROTATE to compensate for device orientation
* fixup! Add PS2_MOUSE_ROTATE to compensate for device orientation
* Reformat with IndentPPDirectives: AfterHash as per #6316
* Define NO_ACTION_MACRO/FUNCTION in header instead of makefile when LTO is enabled
Currently, boards and keymaps that define NO_ACTION_MACRO/FUNCTION unconditionally
will not compile with LTO_ENABLE (#8604). This fixes the issue by moving the
definitions from common.mk to action.h, which enables us to check for previous
definitions of those macros (this cannot be done in a makefile).
* Remove LTO checks in templates
Since now NO_ACTION_MACRO/FUNCTION are defined as needed in action.h (which is
included by quantum.h), checking for LTO in keyboard and user code is no
longer required.
* Update LTO_ENABLE docs
* Change _delay_ms/us() to wait_ms/us()
* Switch to platform-agnostic GPIO macros
* Add AVR spi_master and migrate Adafruit BLE code
* Set verbose back to false
* Add clock divisor, bit order and SPI mode configuration for init
* Add start and stop functions
* Move configuration of mode, endianness and speed to `spi_start()`
* Some breaks here would be good
* Default Adafruit BLE clock divisor to 4 (2MHz on the Feather 32U4)
* Remove mode and divisor enums
* Add some docs
* No hr at EOF
* Add links in sidebar
* rewrite usbhid feature on vusb
* Apply suggestions from code review
