2024-09-24ASoC: atmel: mchp-pdmc: Skip ALSA restoration if substream runtime is ↵Andrei Simion
uninitialized Update the driver to prevent alsa-restore.service from failing when reading data from /var/lib/alsa/asound.state at boot. Ensure that the restoration of ALSA mixer configurations is skipped if substream->runtime is NULL.

2024-09-13ASoC: atmel: mchp-pdmc: Retain Non-Runtime ControlsCodrin Ciubotariu
Avoid removing these controls, as doing so can cause issues if the stream is initiated from another control. Ensure these controls remain intact when the stream is started or finished. Instead of removing them, return an -EBUSY error code to indicate that the controller is busy, especially when the audio filter and the SINC filter are in use.

2024-09-09ASoC: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all drivers below sound/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2023-09-01ASoC: dmaengine: Drop unused iov_iter for process callbackTakashi Iwai
Passing the iov_iter to the process callback is rather buggy, as the iterator has been already processed for playback. Similarly, it makes the copy for capture buggy after the process callback reading the iterator out. Moreover, all existing process callbacks don't refer to the passed iterator at all. So, it's better to drop the argument from the process callback.

2023-08-18ASoC: dmaengine: Use iov_iter for process callback, tooTakashi Iwai
Along with the conversion to PCM copy ops, use the iov_iter for the pointer to be passed to the dmaengine process callback, too. It avoids the direct reference of iter_iov_addr(), and it can potentially help for the drivers to access memory properly (although both atmel and stm drivers don't use the given buffer address at all for now).

2023-03-20ASoC: atmel: mchp-pdmc: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-02-28ASoC: mchp-pdmc: fix poc noise at capture startupClaudiu Beznea
Microchip PDMC IP doesn't filter microphone noises on startup. By default, it captures data received from digital microphones after the MCHP_PDMC_MR.EN bits are set. Thus when enable is set on PDMC side the digital microphones might not be ready yet and PDMC captures data from then in this time. This data captured is poc noise. To avoid this the software workaround is to the following: 1/ enable PDMC channel 2/ wait 150ms (on SAMA7G5-EK setup) 3/ execute 16 dummy reads from RHR 4/ clear interrupts 5/ enable interrupts 6/ enable DMA channel Fixes: 50291652af52 ("ASoC: atmel: mchp-pdmc: add PDMC driver") Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> Link: https://lore.kernel.org/r/20230228110145.3770525-4-claudiu.beznea@microchip.com Signed-off-by: Mark Brown <broonie@kernel.org>

Add support for suspend to RAM by re-aranging the lines in switch..case from mchp_pdmc_trigger() and saving/restoring the enabled interrupts. These are necessary as AT91 devices has a special power saving mode (called backup and self-refresh) where most of the SoC parts are powered off and thus we need to reconfigure the PDMC on resume.
