CS42L42 supports automatic type detection, to determine headset type, or headphones. However, automatic type detection does not always work correctly. To improve detection accuracy, manual mode detection can be run. This is already done in the ASoC version of the CS42L42 driver, and this chain adds the same support into the HDA version.
In addition, to better align the ASoC and HDA drivers, the ASoC header file has been moved into the general sound includes, which allows both ASoC and HDA to have access to the header. This improves the maintainability of the HDA driver, and makes it easier to port fixes/features from CS42L42 ASoC to HDA.
