ASoC: nau8824: user configuration of key detection (7b0037fa) · Commits · 戴 / test

The SAR ADC of key press detection varies depending on headset. We can't make a set of common threshold values for every case. Therefore, the driver provides configuration for user and they can set up values by UCM configuration. Signed-off-by:
