[PATCH v3 00/11] Add support for Legion 7 16ACHg6 laptop

From: Lucas Tanure
Date: Tue Nov 23 2021 - 11:33:50 EST


Add support for laptops that have CS35L41 connected to an
HDA codec by I2S and direct I2C/SPI connection to the CPU

Hardware:
- The 16ACHg6 laptop has two CS35L41 amplifiers, connected
to Realtek ALC287 by an I2S bus and by and direct I2C to the CPU.
- The ALC287 codec is connected to the CPU by an HDA bus.
- The CS35L41 has a DSP which will require firmware to be loaded.

Architecture:
- Creation of a library of shared functions for CS35L41 ASoC and HDA
- HDA codec driver (RealTek) and CS35L41 HDA driver are combined
by using component binding, where it uses device names to find the
components and bind to the master
- The HDA CS35L41 driver applies pre-defined registers sequences
for each action in playback for HDA Sound card

Changes from V2:
- Not an RFC
- Create a new HDA driver for CS35L41 instead of using the ASoC one
- Use component binding and device names to find the CS35L41 driver
- Create a shared library for ASoC and HDA CS35L41 drivers

Lucas Tanure (11):
ASoC: cs35l41: Set the max SPI speed for the whole device
ASoC: cs35l41: Convert tables to shared source code
ASoC: cs35l41: Move regmap config struct to shared code
ASoC: cs35l41: Create function for init array of Supplies
ASoC: cs35l41: Move cs35l41_otp_unpack to shared code
ASoC: cs35l41: Move power initializations to reg_sequence
ASoC: cs35l41: Create shared function for errata patches
ASoC: cs35l41: Create shared function for setting channels
ASoC: cs35l41: Create shared function for boost configuration
hda: cs35l41: Add support for CS35L41 in HDA systems
ACPI / scan: Create platform device for CLSA0100 ACPI nodes
