* Add ARRAY_SIZE and CEILING utility macros
* Apply a coccinelle patch to use ARRAY_SIZE
* fix up some straggling items
* Fix 'make test:secure'
* Enhance ARRAY_SIZE macro to reject acting on pointers
The previous definition would not produce a diagnostic for
```
int *p;
size_t num_elem = ARRAY_SIZE(p)
```
but the new one will.
* explicitly get definition of ARRAY_SIZE
* Convert to ARRAY_SIZE when const is involved
The following spatch finds additional instances where the array is
const and the division is by the size of the type, not the size of
the first element:
```
@ rule5a using "empty.iso" @
type T;
const T[] E;
@@
- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)
@ rule6a using "empty.iso" @
type T;
const T[] E;
@@
- sizeof(E)/sizeof(T)
+ ARRAY_SIZE(E)
```
* New instances of ARRAY_SIZE added since initial spatch run
* Use `ARRAY_SIZE` in docs (found by grep)
* Manually use ARRAY_SIZE
hs_set is expected to be the same size as uint16_t, though it's made
of two 8-bit integers
* Just like char, sizeof(uint8_t) is guaranteed to be 1
This is at least true on any plausible system where qmk is actually used.
Per my understanding it's universally true, assuming that uint8_t exists:

* Run qmk-format on core C files touched in this branch

* 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
* Add support for RISC-V builds and GD32VF103 MCU
* Add toolchain selection in chibios.mk based on the mcu selected in
mcu_selection.mk
* Reorder and added comments to chibios.mk to have a streamlined makefile
* Add GD32VF103 mcu to possible targets for QMK.
* Add STM32 compatibility for GD32VF103 MCU, this is hacky but more efficent
then rewriting every driver.
* Add GigaDevice DFU bootloader as flash target, please note that
dfu-util of at least version 0.10 is needed.
* Add analog driver compatibility
* Add apa102 bitbang driver compatibility
* Add ws2812 bitbang driver compatibility
* Add eeprom in flash emulation compatibility
* Allow faster re-builds with ccache
* Add SiPeed Longan Nano to platform files
* Add SiPeed Longan Nano Onekeys
* Make quine compatible with other bootloaders
* Support builds with picolibc
* Add risc-v toolchain to arch and debian/ubuntu scripts
* Add digitizer HID interface for setting the mouse cursor position at
absolute screen coordinates. Tested on Pro Micro, Proton C and
Blackpill.
* Update docs/feature_digitizer.md

* Update tmk_core/protocol/usb_descriptor.c
Co-authored-by: Ryan <fauxpark@gmail.com>
* Add missing copyrights
Add V-USB support
* Add support for digitizer dedicated endpoint for lufa and chibios.
Fix formatting issues
Move digitizer_task definition to the feature's base implementation file
* Run cformat on modified files
* Change digitizer report usage to Digitizer instead of Pen to avoid
pointer disappearing on Windows.
* Update tmk_core/protocol/vusb/vusb.c
Co-authored-by: Ryan <fauxpark@gmail.com>
* Run cformat from docker image
* Remove send_digitizer from host_driver_t and instead rely on the
declaration being the interface to the implementation in each
HW-specific usb implementation.
* Fix build : send_digitizer shouldn't be static in vusb and add
weak-linkage implementation for tests without usb implementation
* Change digitizer user interface to match pointing device's
* Update documentation with new API

* Rewrite APA102 support
The APA102 source was broken by commit 16a15c1cfc as it did not include the
quantum header. This commit addresses that, as well as other issues with
transferring bytes over the SPI interface, i.e. it was not setting the
clock pin back to low after sending a bit.
The deviation when sending the end frame is kept, but updated to the
latest from the referenced project.
Finally, these changes expose the global LED brightness parameter
of the APA102. Brightness values are configurable through
`APA102_DEFAULT_BRIGHTNESS` and `APA102_MAX_BRIGHTNESS`.
* Fix typo in led brightness extern
* Move driver out of AVR directory and add delay for ARM
* Experimental APA102 support on AVR and ARM
Co-authored-by: Alde Rojas <hello@alde.io>
* Refactor apa102_send_byte() calls to a loop
* Implement io_wait function for ARM
* Move APA102 drivers to own directory, fix copyright notice
* Add APA102 keymap to handwired/onekey
* Simplify RGBLIGHT_ENABLE/DRIVER option handling
