The CS35L41 Amplifier contains a DSP, capable of running firmware.
The firmware can run algorithms such as Speaker Protection, to ensure
that playback at high gains do not harm the speakers.
Adding support for CS35L41 firmware into the CS35L41 HDA driver also
allows us to support several extra features, such as hiberation
and interrupts.
The chain adds support in stages:
- General fixes to improve generalization and code re-use inside
the CS35L41 HDA driver.
- Add support for interrupts into the driver, which is required
for complete support of the firmware.
- Refactor ASoC CS35L41 code which deals with firmware to allow
for code re-use inside the CS35L41 HDA driver.
- Add support for loading firmware and tuning files from file system,
and creating alsa controls to control it.
- Support firmware load paths for different hardware systems.
- Support suspend/resume in the driver when using firmware. The firmware
supports hibernation, which allows the CS35L41 to drop into a low
power mode during suspend.
- Support the ability to unload firmware, swap and reload the firmware.
This is to allow different firmware to run during calibration.
The intended use-case is to load the firmware once on boot, and the driver
autmatically tries to load the firmware after it binds to the HDA driver.
This behaviour can be switched off using a kconfig, if desired.
