2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2022-02-11button: adc: set state to pressed when the voltage is closest to nominalPeter Cai
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>
