The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed for portable applications. It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. Separate firmware/tuning is not required for individual SKUs so this firmware should support all deployments of cs42l43. Firmware version: 2.4.0 Signed-off-by: Charles Keepax <ckeepax@opensource.cirrus.com>
Linux firmware
This repository contains all these firmware images which have been extracted from older drivers, as well various new firmware images which we were never permitted to include in a GPL'd work, but which we have been permitted to redistribute under separate cover.
The upstream repository is located at https://gitlab.com/kernel-firmware/linux-firmware.git.
Submitting firmware
To submit firmware to this repository, please do one of the following:
- open a MR upstream
- send a git binary diff to
linux-firmware@kernel.org - send a git pull request to:
linux-firmware@kernel.org
Quality
If your commit adds new firmware, it must update the WHENCE file to
clearly state the license under which the firmware is available, and
that it is redistributable. Being redistributable includes ensuring
the firmware license provided includes an implicit or explicit
patent grant to end users to ensure full functionality of device
operation with the firmware. If the license is long and involved, it's
permitted to include it in a separate file and refer to it from the
WHENCE file (IE 'See LICENSE.foo for details.').
And if it were possible, a changelog of the firmware itself.
To maintain consistent quality on the repository, please run the following before submitting a patch:
make check
If you don't have pre-commit installed, you can install it with:
pip install pre-commit
Your commit must contain a Signed-Off-By: from someone authoritative on
the licensing of the firmware in question (i.e. from within the company
that owns the code).
