ASoC: rt-sdw*: add func to all error logs

2024-03-28T19:31:12Z

The drivers for Realtek SoundWire codecs use similar logs, which is problematic to analyze problems reported by CI tools, e.g. "Failed to get private value: 752001 => 0000 ret=-5". It's not uncommon to have several Realtek devices on the same platform, having the same log thrown makes support difficult. This patch adds __func__ to all error logs which didn't already include it. No functionality change, only error logs are modified.

ASoC: rt700: enable pm_runtime in probe, keep status as 'suspended'

2023-08-07T13:32:24Z

This patch suggests enabling pm_runtime during the probe, but marking the device as 'active' only after it is enumerated. That will force a dependency between the card and the codec, pm_runtime_get_sync() will have to wait for the codec device to resume and hence implicitly wait for the enumeration/initialization to be completed. In the nominal case where the codec device is already active the get_sync() would only perform a ref-count increase. The changes are directly inspired by RT711 and RT711-sdca changes.

ASoC: SoundWire codecs: make regmap cache-only in probe

2023-08-07T13:32:20Z

The SoundWire bus may start after the probe where the SoundWire ASoC components are registered. This creates a time window where the card can be created and the registers be accessed. As discussed on the mailing list, we can't really control when codecs are enumerated and initialized, but we can make sure the access to the codecs is cached until the hardware is accessible. This patch configures regcache_cache_only() with a 'true' parameter in the probe function, and a 'false' parameter in the io_init routine. The rt5682 is handled through a different patch due to its specific cache handling.

ASoC: codecs: rt700-sdw: simplify set_stream

2023-03-29T14:03:04Z

Using a dynamic allocation to store a single pointer is not very efficient/useful. Worse, the memory is released in the SoundWire stream.c file, but still accessed in the DAI shutdown, leading to kmemleak reports. And last the API requires the previous stream information to be cleared when the argument is NULL. Simplify the code to address all 3 problems.

ASoC: codecs: soundwire: call pm_runtime_resume() in component probe

2022-06-17T17:37:59Z

Make sure that the bus and codecs are pm_runtime active when the card is registered/created. This avoid timeouts when accessing registers.

ASoC: codecs: rt700/rt711/rt711-sdca: resume bus/codec in .set_jack_detect

2022-06-07T19:37:32Z

The .set_jack_detect() codec component callback is invoked during card registration, which happens when the machine driver is probed. The issue is that this callback can race with the bus suspend/resume, and IO timeouts can happen. This can be reproduced very easily if the machine driver is 'blacklisted' and manually probed after the bus suspends. The bus and codec need to be re-initialized using pm_runtime helpers. Previous contributions tried to make sure accesses to the bus during the .set_jack_detect() component callback only happen when the bus is active. This was done by changing the regcache status on a component remove. This is however a layering violation, the regcache status should only be modified on device probe, suspend and resume. The component probe/remove should not modify how the device regcache is handled. This solution also didn't handle all the possible race conditions, and the RT700 headset codec was not handled. This patch tries to resume the codec device before handling the jack initializations. In case the codec has not yet been initialized, pm_runtime may not be enabled yet, so we don't squelch the -EACCES error code and only stop the jack information. When the codec reports as attached, the jack initialization will proceed as usual.

The workqueues are initialized in the io_init functions, which isn't quite right.

ASoC: rt7*-sdw: harden jack_detect_handler

2022-06-07T19:37:30Z

Realtek headset codec drivers typically check if the card is instantiated before proceeding with the jack detection. The rt700, rt711 and rt711-sdca are however missing a check on the card pointer, which can lead to NULL dereferences encountered in driver bind/unbind tests.
