2024-11-12ASoC: max9768: Fix event generation for playback muteMark Brown
The max9768 has a custom control for playback mute which unconditionally returns 0 from the put() operation, rather than returning 1 on change to ensure notifications are generated to userspace. Check to see if the value has changed and return appropriately.

2024-05-03ASoC: codecs: Drop explicit initialization of struct ↵Uwe Kleine-König
i2c_device_id::driver_data to 0 These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

2023-09-11ASoC: max9768: Convert to use GPIO descriptorsLinus Walleij
The MAX9768 is pretty straight forward to convert to GPIO descriptors. To name the GPIO properties, I looke at the bindings in maxim,max9759.yaml which names these GPIO "mute" and "shutdown" respectively. No board files using platform data exist in the kernel, new users can use GPIO descriptor tables if desired.

2023-05-08ASoC: Switch i2c drivers back to use .probe()Uwe Kleine-König
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2022-04-11ASoC: max9*: use simple i2c probe functionStephen Kitt
The i2c probe functions here don't use the id information provided in their second argument, so the single-parameter i2c probe function ("probe_new") can be used instead. This avoids scanning the identifier tables during probes.

2014-04-14ASoC: Add snd_soc_kcontrol_codec() helper functionLars-Peter Clausen
For CODEC controls snd_kcontrol_chip() currently returns a pointer to the CODEC that registered the control. With the upcoming consolidation of platform and CODEC controls this will change. Prepare for this by introducing the snd_soc_kcontrol_codec() helper function that will hide the implementation details of how the CODEC for a control can be obtained. This will allow us to change this easily in the future. The patch also updates all CODEC drivers to use the new helper function.
