* ASoC: atmel: mchp-pdmc: Retain Non-Runtime ControlsCodrin Ciubotariu2024-09-131-42/+15
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | Improve the DMA descriptor calculation by dividing the period size by the product of sample size and DMA chunk size, rather than just DMA chunk size. Ensure that all DMA descriptors start from a well-aligned address to improve the reliability and efficiency of DMA operations and avoid potential issues related to misaligned descriptors.

* ASoC: Switch back to struct platform_driver::remove()Uwe Kleine-König2024-09-099-9/+9
| | | | | | | | | | | | | | | 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.

* ASoC: atmel: mchp-i2s-mcc: Improve maxburst calculation for better performanceCodrin Ciubotariu2024-09-051-5/+33
| | | | | | | | | | | | | | | | | | | | | | | The period size represents the size of the DMA descriptor. To ensure all DMA descriptors start from a well-aligned address, the period size must be divided by (sample size * maxburst), not just by maxburst. This adjustment allows for computing a higher maxburst value, thereby increasing the performance of the DMA transfer. Previously, snd_pcm_lib_period_bytes() returned 0 because the runtime HW parameters are computed after the hw_params() callbacks are used. To address this, we now use params_*() functions to compute the period size accurately. This change optimizes the DMA transfer performance by ensuring proper alignment and efficient use of maxburst values. [andrei.simion@microchip.com: Reword commit message and commit title.

* ASoC: Use *-y instead of *-objs in MakefileMark Brown2024-05-081-15/+15
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge series from Takashi Iwai <tiwai@suse.de>: This is a series of trivial cleanup patches for ASoC to correct the *-objs suffix in Makefile. The other ALSA code has been covered by a previous patch set https://lore.kernel.org/r/20240507135513.14919-1-tiwai@suse.de As was suggested in a patch review, *-objs suffix in Makefile is basically a wrong use nowadays for kernel driver modules. They should be replaced with *-y suffix instead. This is a result of systematic conversions, separated per directory. Only lightly compile-tested.

* ASoC: Explicitly include correct DT includesRob Herring2023-10-093-3/+1
| | | | | | | | | | | | | | | | | | | The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

| | | | | | | | | | | | | | | | 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.

* ASoC: mchp-pdmc: fix poc noises when startingMark Brown2023-02-281-5/+48
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge series from Claudiu Beznea <claudiu.beznea@microchip.com>: To start capture on Microchip PDMC the enable bits for each supported microphone need to be set. After this bit is set the PDMC starts to receive data from microphones and it considers this data as valid data. Thus if microphones are not ready the PDMC captures anyway data from its lines. This data is interpreted by the human ear as poc noises. To avoid this the following software workaround need to be applied when starting capture: 1/ enable PDMC channel 2/ wait 150ms 3/ execute 16 dummy reads from RHR 4/ clear interrupts 5/ enable interrupts 6/ enable DMA channel For this workaround to work step 6 need to be executed at the end. For step 6 was added patch 1/3 from this series. With this, component DAI driver sets its struct snd_soc_component_driver::start_dma_last = 1 and proper action is taken based on this flag when starting DAI trigger vs DMA.
| * ASoC: mchp-pdmc: fix poc noise at capture startupClaudiu Beznea2023-02-281-5/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | ASoC: sam9g20ek: Disable capture unless building with microphone inputMark Brown2023-02-281-0/+3
|/ | | | | | | | | | | | | | | | Without modification the AT91SAM9G20-EK has no capture support, none of the inputs of the CODEC are wired to anything to useful and there are no paths supporting loopback. Since the audio is clocked from the CODEC and the DAPM inputs are marked as unusable this means that capture will fail to transfer any data as the ADC path can't be powered up. Flag this in the device description so apps don't see unusable capture support, guarded with the existing optional define for mic input.
