When helix/rev2 was using split_common, it didn't work properly and I couldn't type on the right hand side.
The cause is that the following code, added in 0.16.0 to `quantum/keyboard.c`, does not include `quantum/split_common/split_util.h` but instead includes `keyboards/helix/rev2/split_util.h`. Therefore, `split_pre_init()/split_post_init()` in `quantum/split_common/split_util.c` was not called.
```c
#ifdef SPLIT_KEYBOARD
# include "split_util.h"
#endif
```
* add licenses message to helix/rev2 files
* Minimize the processing of helix/rev2/local_features.mk
* Changed helix/rev2 default setting to use split_common
* fix helix/rev2:edvorakjp build error
* Remove unnecessary '#include' from keymap.c
* helix keymaps Workaround for build errors. five_rows_jis, fraanrosi, froggy, froggy_106, yshrsmz
* Revert "fix helix/rev2:edvorakjp build error"
This reverts commit 731dbbe15155b3efe2ff9f5ad61c7d0cf529e837.
Separated into a single PR #16433.
* Revert "Changed helix/rev2 default setting to use split_common"
This reverts commit e76dbd7762e06e0781ee004213878b1a5029fa98.
* add 'SPLIT_*_STATE_ENABLE' into helix/rev2/config.h
* Revert "helix keymaps Workaround for build errors. five_rows_jis, fraanrosi, froggy, froggy_106, yshrsmz"
This reverts commit 9b316c1c6a532f908f2ac430233089797ce7c794.
* change helix:default to use split_common
* change helix:five_rows to use split_common
* add comment into helix/rev2/rules.mk
* change helix:led_test to use split_common
* atlas_65.h: add matrix diagram
* atlas_65.h: apply linting
- convert tabs to spaces
- four-space indent
- align backslashes in layout macro
* atlas_65.h: adjust layout macro alignment
Visually separates each side. White-space-only change.
* physically arrange layout macro
Move the matrix position identifiers in the layout macro to resemble the assembled keyboard's layout.
- move `k46` (right side B) to the fourth (Shift) row
- move each of `k1E`, `k2E` and `k3E` (right side navigation keys) up one row
- update keymaps to match
* update maintainer data
Update the maintainer data in `info.json` and `readme.md`.
* Glacier: Community Layout support
Enables the Glacier to use QMK's `tkl_f13_ansi_tsangan` community layout.
- rename `LAYOUT` to `LAYOUT_tkl_f13_ansi_tsangan`
- add `LAYOUTS` rule to `rules.mk`
* info.json: correct maintainer value
Use the maintainer's GitHub username.
'helix/rev2/keymaps/edvorakjp' was no longer buildable due to changes made by #14864.
The reason is that the prototype of `oled_task_user()` was changed in keymaps/edvorakjp/oled.c, but keymaps/edvorakjp/oled.h was not changed.
Therefore, I modified the prototype in keymaps/edvorakjp/oled.h.
* apply friendly formatting to info.json
* rebuild Configurator layout data
KLE Rotation leads to incorrect layout data when converted to `info.json` format.
* add matrix diagram to sabre.h
