ASoC: da7219: Fix pole orientation detection on OMTP headsets when playing music
The OMTP pin define headsets can be mis-detected as line out instead of OMTP, causing obvious issues with audio quality. This patch is to put increased resistances within the device at a suitable point. To solve this issue better, the new mechanism setup ground switches with conditional delay control and these allow for more stabile detection process to operate as intended. This conditional delay control will not impact the hardware process but use extra system resource. This commit improves control of ground switches in the AAD logic.
