ASoC: cs35l56: Enable low-power hibernation mode on i2c This can now be re-enabled as the sequence to reliably wake the device has been implemented in the shared code.

ASoC: cs35l56: Use pm_ptr() Use pm_ptr() when setting the pointer to the dev_pm_ops so that it will be NULL if CONFIG_PM is disabled. This allows the dev_pm_ops to be compiled out in that case.

ASoC: cs35l56: Disable low-power hibernation mode Do not allow the CS35L56 to be put into its lowest power "hibernation" mode. This only affects I2C because "hibernation" is already disabled on SPI and SoundWire. Recent firmwares need a different wake-up sequence. Until that sequence has been specified, the chip "hibernation" mode must be disabled otherwise it can intermittently fail to wake. THIS WILL NOT APPLY CLEANLY TO 6.5 AND EARLIER: We will send a separate backport patch to stable.

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: Switch two more i2c drivers back to use .probe() The previous conversion back to .probe() applied in commit 9abcd24002bf ("ASoC: Switch i2c drivers back to use .probe()") was created based on v6.3. Since then two more drivers were added which need to be convert back in the same way before eventually .probe_new() can be dropped from struct i2c_driver.

ASoC: cs35l56: Rework IRQ allocation The irq member was being set before calling the init function and then cs35l56_irq_request() was called only when the init was successful. However cs35l56_release() calls devm_free_irq() when the irq member is set and therefore if init() fails then this will cause an attempted free of an unallocated IRQ. Instead pass the desired IRQ number to the cs35l56_irq_request() function and set cs35l56->irq only when it has been successfully allocated.

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.
