| * | button: adc: set state to pressed when the voltage is closest to nominal | Peter Cai | 2022-02-11 | 1 | -5/+16 |
| | | | | | | | | | | | | | | 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. Signed-off-by: Peter Cai <peter@typeblog.net> | ||||
