- 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).

M5Stack Cardputer internal GPIO matrix keyboard: 4 rows x 14 columns, scanned via 3
|
|
binary-encoded column-select output pins and 7 row input pins. Exposes a KEYBOARD_TYPE
|
|
device. Modifier keys (fn/shift/ctrl/opt/alt/tab) are consumed internally and never emitted
|
|
as their own key events. Regular keys emit their ASCII character (shifted variant when
|
|
shift or ctrl is held). With fn held: del -> forward delete, enter -> enter, ` -> escape,
|
|
, -> left, / -> right, ; -> previous (group navigation), . -> next (group navigation).
