2024-09-09ASoC: Switch back to struct platform_driver::remove()Uwe Kleine-König1-1/+1
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.

pm_runtime_allow() is not needed for ACP child platform devices. Replace pm_runtime_allow() with pm_runtime_mark_last_busy() & pm_runtime_set_active() in pm_runtime enable sequence for ACP child platform drivers.

2023-03-20ASoC: amd: raven: acp3x-pdm-dma: Convert to platform remove callback ↵Uwe Kleine-König1-3/+2
returning void 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.

2023-02-02ASoC: amd: renoir: Add a module parameter to influence pdm_gainMario Limonciello1-1/+7
In case of regressions for any users that the new pdm_gain value is too high and for additional debugging, introduce a module parameter that would let them configure it. This parameter should be removed in the future: * If it's determined that the parameter is not needed, just hardcode the correct value as before * If users do end up using it to debug and report different values we should introduce a config knob that can have policy set by ucm.

Change the legacy DAI naming flag from opting in to the new scheme (non_legacy_dai_naming), to opting out of it (legacy_dai_naming). These drivers appear to be on the CPU side of the DAI link and currently uses the legacy naming, so add the new flag.

2022-02-28ASoC: amd: pcm-dma: Use platform_get_irq() to get the interruptMeng Tang1-5/+2
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypassed the hierarchical setup and messed up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq().

2021-08-02ASoC: amd: Fix reference to PCM buffer addressTakashi Iwai1-1/+1
PCM buffers might be allocated dynamically when the buffer preallocation failed or a larger buffer is requested, and it's not guaranteed that substream->dma_buffer points to the actually used buffer. The driver needs to refer to substream->runtime->dma_addr instead for the buffer address.

2020-08-03ASoC: amd: renoir: restore two more registers during resumeHui Wang1-20/+9
Recently we found an issue about the suspend and resume. If dmic is recording the sound, and we run suspend and resume, after the resume, the dmic can't work well anymore. we need to close the app and reopen the app, then the dmic could record the sound again. For example, we run "arecord -D hw:CARD=acp,DEV=0 -f S32_LE -c 2 -r 48000 test.wav", then suspend and resume, after the system resume back, we speak to the dmic. then stop the arecord, use aplay to play the test.wav, we could hear the sound recorded after resume is weird, it is not what we speak to the dmic. I found two registers are set in the dai_hw_params(), if the two registers are set during the resume, this issue could be fixed. Move the code of the dai_hw_params() into the pdm_dai_trigger(), then these two registers will be set during resume since pdm_dai_trigger() will be called during resume. And delete the empty function dai_hw_params().
