Dell's laptops Inspiron 3500, Inspiron 3501, Inspiron 3505 are using Cirrus Logic CS8409 HDA bridge with CS42L42 companion codec.
The CS8409 is a multichannel HD audio routing controller. CS8409 includes support for four channels of digital microphone data and two bidirectional ASPs for up to 32 channels of TDM data or 4 channels of I2S data. The CS8409 is intended to be used with a remote companion codec that implements high performance analog functions in close physical proximity to the end-equipment audio port or speaker driver.
The CS42L42 is a low-power audio codec with integrated MIPI SoundWire interface or I2C/I2S/TDM interfaces designed for portable applications. It provides a high-dynamic range, stereo DAC for audio playback and a mono high-dynamic-range ADC for audio capture
Changes since version 1:
ALSA: hda/cirrus: Increase AUTO_CFG_MAX_INS from 8 to 18
- No change
ALSA: hda/cirrus: Add support for CS8409 HDA bridge and CS42L42 companion codec.
- Removed redundant fields in fixup table
- Handle gpio via spec->gpio_dir, spec->gpio_data and spec->gpio_mask
- Moved cs8409_cs42l42_init() from patch 2, to handle resume correctly
ALSA: hda/cirrus: Add jack detect interrupt support from CS42L42 companion codec.
- Run scripts/checkpatch.pl, fixed new warnings
ALSA: hda/cirrus: Add Headphone and Headset MIC Volume Control
- Moved control values to cache to avoid i2c read at each time.
