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
CS42L42 is connected to CS8409 HDA bridge via I2C and I2S.
CS8409 CS42L42
------- --------
ASP1.A TX --> ASP_SDIN
ASP1.A RX <-- ASP_SDOUT
GPIO5 --> RST#
GPIO4 <-- INT#
GPIO3 <-- WAKE#
GPIO7 <-> I2C SDA
GPIO6 --> I2C CLK
Tested on DELL Inspiron-3500, DELL Inspiron-3501, DELL Inspiron-3505
This patch will register CS8409 with sound card and create
input/output paths and two input devices, initialise CS42L42
companion codec and configure it for ASP TX/RX TDM mode,
24bit, 48kHz.

Changes in v3:
- Fixed uninitialized variable warning (Reported-by: kernel test robot
<l...@intel.com>)
- Moved gpio setup into s8409_cs42l42_hw_init()
- Improved susped() implementation
