ASoC: cs35l56: Add support for CS35L54 and CS35L57 The CS35L54 and CS35L57 are Boosted Smart Amplifiers. The CS35L54 has I2C/SPI control and I2S/TDM audio. The CS35L57 also has SoundWire control and audio. The hardware differences between L54, L56 and L57 do not affect the driver control interface so they can all be handled by the same driver.

ASoC: cs35l56: Apply amp calibration from EFI data If there are factory calibration settings in EFI, extract the settings and write them to the firmware calibration controls. This must be done after any firmware or coefficients have been downloaded to the amp.

ASoC: cs35l56: Move runtime suspend/resume to shared library The majority of runtime_suspend and runtime_resume handling doesn't have anything specific to the ASoC driver, so can be shared by the HDA driver.

ASoC: cs35l56: Move shared data into a common data structure The ASoC and HDA drivers have structures that contain some of the same information - instead of maintaining two locations for this data the drivers should share a common data structure as this will enable common utility functions to be created. The first step is to move the location of these members in the ASoC driver.

ASoC: cs35l56: Don't return a value from cs35l56_remove() cs35l56_remove() always returns 0. Two of the functions that call it are void and the other one should only return 0. So there's no point returning anything from cs35l56_remove().

ASoC: cs35l56: Re-patch firmware after system suspend Check during cs35l56_system_resume() whether the firmware patch must be applied again. The FIRMWARE_MISSING flag in the PROTECTION_STATUS register indicates whether the firmware has been patched. In non-secure mode the FIRMWARE_MISSING flag is cleared at the end of dsp_work(). If it is set after system-resume we know that dsp_work() must be run again. In secure mode the pre-OS loader will have done the secure patching and cleared the FIRMWARE_MISSING flag. So this flag does not tell us whether firmware memory was lost. But the driver could only be downloading non-secure tunings, which is always safe to do. If the driver has control of RESET we will have asserted it during suspend so the firmware patch will have been lost. The driver would only have control of RESET in non-secure mode.

ASoC: cs35l56: Add basic system suspend handling This adds the main handling for system suspend but does not handle re-patching the firmware after system resume. This is a multi-stage suspend and resume because if there is a RESET line it is almost certain that it will be shared by all the amps. So every amp must have done its suspend before we can assert RESET. Likewise we must de-assert RESET before the amps can resume. It's preferable to assert RESET before we turning off regulators, and while they power up. The actual suspend and resume is done by using the pair pm_runtime_force_suspend() and pm_runtime_force_resume() to re-use our runtime suspend/resume sequences. pm_runtime_force_suspend() will disable our pm_runtime. If we were runtime-resumed it calls our runtime_suspend(). pm_runtime_force_resume() re-enables pm_runtime and if we were originally runtime-resumed before the pm_runtime_force_suspend() it calls our runtime_resume(). Otherwise it leaves us runtime-suspended. The general process is therefore: suspend() -> finish dsp_work and then run our runtime_suspend suspend_late() -> assert RESET and turn off supplies resume_early() -> enable supplies and de-assert RESET resume() -> pm_runtime_force_resume() In addition, to prevent the IRQ handler running in the period between pm_runtime_force_suspend() and pm_runtime_force_resume() the parent IRQ is temporarily disabled: - from suspend until suspend_noirq - from resume_noirq until resume Signed-off-by: Richard Fitzgerald <rf@opensource.cirrus.com> Link: https://lore.kernel.org/r/20230411152528.329803-6-rf@opensource.cirrus.com Signed-off-by: Mark Brown <broonie@kernel.org>

ASoC: cs35l56: Add driver for Cirrus Logic CS35L56 The CS35L56 combines a high-performance mono audio amplifier, Class-H tracking inductive boost converter, Halo Core(TM) DSP and a DC-DC boost converter supporting Class-H tracking. Supported control interfaces are I2C, SPI or SoundWire. Supported audio interfaces are I2S/TDM or SoundWire. Most chip functionality is controlled by on-board ROM firmware that is always running. The driver must apply patch/tune to the firmware before using the CS35L56.
