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.

2022-08-23ASoC: nau8821: Implement hw constraint for ratesTakashi Iwai
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 Brown
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.

2022-06-27ASoC: nau*: Remove now redundant non_legacy_dai_naming flagCharles Keepax
The ASoC core has now been changed to default to the non-legacy DAI naming, as such drivers using the new scheme no longer need to specify the non_legacy_dai_naming flag.

2022-04-11ASoC: nau8*: 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.
