* Proporly handle multiple conditonal layers w/ the same target
`then-layer` values.
* Move handling to work callback, to avoid re-entrance for cascading
layers enabling other layers.
* Move to ZephyrBuildConfig package based on Zephyr best practices.
* Support multiple shields properly, e.g. -DSHIELD="foo bar", which
allows using existing upstream shields like `ssd1306_128x64` along
with another ZMK shield.
* Properly *add* the "ZMK config" .conf file to the conf file list,
so that existing board .conf files in `app/boards/<board>.conf` are
properly honored still. Needed for overrides to usptream boards when
combined with a local `<shield>.conf` file.
* Add new API/status to track state of the
peripheral connection to the central.
* Add new peripheral status widget for displaying
the current status of the connection to
the central.
Rewrote the direct GPIO kscan driver to match the improvements made to
the matrix driver in 82cb762698 and
f946dc6893. It now uses the same
debouncing system as the matrix driver.
* Remove MISO pin from pinctrl for BDN9 rev2 board, to avoid
the 4th switch being set up for an alternate function, which
was causing spurious key press events to be triggered.
CONFIG_ZMK_BATTERY_NRF_VDDH and CONFIG_ZMK_BATTERY_VOLTAGE_DIVIDER are
now automatically enabled if a DT node with the matching "compatible"
property is present and enabled, so they no longer need to be manually
set for each board.
The key scanning drivers are now automatically enabled when a DT node
with the matching "compatible" property is present and enabled, so they
no longer need to be manually set for each board.
battery.c now uses the zmk,battery chosen node to select a battery
sensor. Using the node labeled "BATTERY" is maintained for backwards
compatibility but is now deprecated. Custom boards should switch to
using the chosen node.
