2024-05-03ASoC: codecs: Drop explicit initialization of struct ↵Uwe Kleine-König1-1/+1
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.

2023-08-23ASoC: nau8821: Improve AMIC recording performance.Seven Lee1-1/+41
Since the hardware may be designed as a single-ended input, the headset mic record only supports single-ended input on the left side. This patch will enhance microphone recording performance for single-end.

2023-07-23ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detectEdson Juliano Drosdeck1-0/+41
Add a quirk mechanism to allow specifying that active-high jack-detection should be used on platforms where this info is not available in devicetree. And add an entry for the Positivo CW14Q01P-V2 to the DMI table, so that jack-detection will work properly on this laptop.

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.

2022-08-23ASoC: nau8821: Implement hw constraint for ratesTakashi Iwai1-30/+36
nau8821 driver restricts the sample rate with over sampling rate, but currently it barely bails out at hw_params with -EINVAL error (with a kernel message); this doesn't help for user-space to recognize which rate can be actually used. This patch introduces the proper hw constraint for adjusting the available range of the sample rate depending on the OSR setup, as well as some code cleanup, for improving the communication with user-space. Now applications can know the valid rate beforehand and reduces the rate appropriately without errors.

2022-07-19ASoC: nau8821: Don't unconditionally free interruptMark Brown1-10/+0
The remove() operation unconditionally frees the interrupt for the device but we may not actually have an interrupt so there might be nothing to free. Since the interrupt is requested after all other resources we don't need the explicit free anyway, unwinding is guaranteed to be safe, so just delete the remove() function and let devm take care of things.

2022-04-11ASoC: nau8*: use simple i2c probe functionStephen Kitt1-3/+2
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.
