button: add missing ADC dependency for BUTTON_ADC

2024-03-14T10:20:04+00:00

The BUTTON_ADC symbol guards the compilation of button-adc driver whose
name very well makes it explicit that it requires ADC support to be
enabled.

Fix build issue of button-adc driver when ADC support isn't enabled by
making sure it cannot be built without ADC support.

button: qcom-pmic: demote "unknown button" message to debug

2024-02-14T17:21:50+00:00

This message isn't an error (there can be a watchdog subnode for example)
but it shouldn't be printed unless this driver is being debugged. Demote
it to a debug print.

button: qcom-pmic: introduce Qualcomm PMIC button driver

2024-01-16T12:26:53+00:00

Qualcomm PMICs include a "pon" function which handles two buttons, the
power button and "resin" button (usually volume down). Introduce a new
driver following upstream Linux DT to enable these and map them to Enter
and Down respectively to enable use in boot menus.

button: adc: set state to pressed when the voltage is closest to nominal

2022-02-11T14:00:47+00:00

In the Linux implementation of adc-keys
(drivers/input/keyboard/adc-keys.c), `press-threshold-microvolt` is not
really interpreted as a threshold, but rather as the "nominal voltage"
of the button. When the voltage read from the ADC is closest to a
button's `press-threshold-microvolt`, the button is considered pressed.

This patch reconciles the behavior of button-adc with Linux's adc-keys
such that device trees can be synchronized with minimal modifications.
