- Added modular device support and devicetree bindings for ILI9341, ILI9488, CST816S, XPT2046, and GPIO button input, updating several board configurations for display/touch/backlight/keyboard/battery. - Added a setting to control deprecated HAL usage (device property + Kconfig).

GPIO button(s) that emulate UI navigation keys, for boards with only 1 or 2 physical
|
|
buttons instead of a full keyboard or touchscreen. Exposes a KEYBOARD_TYPE device: each
|
|
button's short/long press is translated to an LVGL navigation key, decided once the
|
|
button is released (so a long press is only recognized after release, matching how long
|
|
a button was actually held).

Primary button GPIO pin. One-button mode (pin-secondary absent): short press = select
|
|
next, long press = press/enter. Two-button mode (pin-secondary present): short press =
|
|
press/enter, long press = close app.

Optional secondary button GPIO pin. When present, enables two-button mode: short press
|
|
= select next, long press = select previous. When absent, the device runs in
|
|
one-button mode (see pin-primary).
