2023-03-20ASoC: Intel: sst: Convert to platform remove callback returning voidUwe Kleine-König1-3/+2
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.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v6.1 This has been a very quiet release for the core but quite a busy one for drivers with a big crop of new drivers and lots of feature additions and fixes to existing ones: - A new string helper parse_int_array_user(). - Improvements to the SOF IPC4 code, especially around trace. - Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silcon systems, Everest ES8326, Intel Sky Lake and Kaby Lake, MediaTek MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450 and Texas Instruments SRC4392 There is a conflict with the conversion of I2C remove functions to void in the cs42l42 driver which is fairly straightforward to resolve but should be highlighted to Linus.

2022-06-09Specify clock provider directly to CPU DAIsMark Brown1-2/+2
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: Currently the set_fmt callback always passes clock provider/consumer with respect to the CODEC. This made sense when the framework was directly broken down into platforms and CODECs. However, as things are now broken down into components which can be connected as either the CPU or CODEC side of a DAI link it simplifies things if each side of the link is just told if it is provider or consumer of the clocks. Making this change allows us to remove one of the last parts of the ASoC core that needs to know if a driver is a CODEC driver, where it flips the clock format specifier if a CODEC driver is used on the CPU side of a DAI link, as well as just being conceptually more consistent with componentisation. The basic idea of this patch chain is to change the set_fmt callback from specifying if the CODEC is provider/consumer into directly specifying if the component is provider/consumer. To do this we add some new defines, and then to preserve bisectability, the migration is done by adding a new callback, converting over all existing CPU side drivers, converting the core, and then finally reverting back to the old callback. Converting the platform drivers makes sense as the existing defines are from the perspective of the CODEC and there are more CODEC drivers than platform drivers. Obviously a fair amount of this patch chain I was only able to build test, so any testing that can be done would be greatly appreciated.

Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ...

2021-08-19ASoC: intel: atom: Fix breakage for PCM buffer address setupTakashi Iwai1-1/+1
The commit 2e6b836312a4 ("ASoC: intel: atom: Fix reference to PCM buffer address") changed the reference of PCM buffer address to substream->runtime->dma_addr as the buffer address may change dynamically. However, I forgot that the dma_addr field is still not set up for the CONTINUOUS buffer type (that this driver uses) yet in 5.14 and earlier kernels, and it resulted in garbage I/O. The problem will be fixed in 5.15, but we need to address it quickly for now. The fix is to deduce the address again from the DMA pointer with virt_to_phys(), but from the right one, substream->runtime->dma_area.

2021-07-30ASoC: intel: atom: Fix reference to PCM buffer addressTakashi Iwai1-2/+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 address should be retrieved from runtime->dma_addr, instead of substream->dma_buffer (and shouldn't use virt_to_phys). Also, remove the line overriding runtime->dma_area superfluously, which was already set up at the PCM buffer allocation.

The SST firmware's media and deep-buffer inputs are hardcoded to S16LE, the corresponding DAIs don't have a hw_params callback and their prepare callback also does not take the format into account. So far the advertising of non working S24LE support has not caused issues because pulseaudio defaults to S16LE, but changing pulse-audio's config to use S24LE will result in broken sound. Pipewire is replacing pulse now and pipewire prefers S24LE over S16LE when available, causing the problem of the broken S24LE support to come to the surface now.
