ASoC: nau8824: user configuration of key detection
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: John Hsu <KCHSU0@nuvoton.com> Signed-off-by: Mark Brown <broonie@kernel.org>
