Subject: [PATCH v2 0/4] ALSA: hda/cirrus: Add support for CS8409 HDA bridge and CS42L42 companion codec

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.
