2024-09-30ASoC: fsl: Use maple tree register cacheMark Brown
Several of the NXP drivers use regmaps with a rbtree register cache. Since the maple tree cache is using a generally more modern data structure which makes implementation choices more suitable for modern systems let's convert these drivers to it. This should have no practical impact.

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.

2024-05-27ASoC: fsl: fsl_easrc: Switch to RUNTIME_PM_OPS()Fabio Estevam
Replace SET_RUNTIME_PM_OPS() with its modern alternative RUNTIME_PM_OPS(). The combined usage of pm_ptr() and RUNTIME_PM_OPS() allows the compiler to evaluate if the runtime suspend/resume() functions are used at build time or are simply dead code. This allows removing the __maybe_unused notation from the runtime suspend/resume() functions.

2023-10-23ASoC: fsl: Fix PM disable depth imbalance in fsl_easrc_probeZhang Shurong
The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context. We fix it by calling pm_runtime_disable when error returns.

2023-03-20ASoC: fsl: fsl_easrc: 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.

2020-06-22ASoC: soc-component: merge snd_soc_component_read() and ↵Kuninori Morimoto
snd_soc_component_read32() We had read/write function for Codec, Platform, etc, but these has been merged into snd_soc_component_read/write(). Internally, it is using regmap or driver function. In read case, each styles are like below regmap ret = regmap_read(..., reg, &val); driver function val = xxx->read(..., reg); Because of this kind of different style, to keep same read style, when we merged each read function into snd_soc_component_read(), we created snd_soc_component_read32(), like below. commit 738b49efe6c6 ("ASoC: add snd_soc_component_read32") (1) val = snd_soc_component_read32(component, reg); (2) ret = snd_soc_component_read(component, reg, &val); Many drivers are using snd_soc_component_read32(), and some drivers are using snd_soc_component_read() today. In generally, we don't check read function successes, because, we will have many other issues at initial timing if read function didn't work. Now we can use soc_component_err() when error case. This means, it is easy to notice if error occurred. This patch aggressively merge snd_soc_component_read() and _read32(), and makes snd_soc_component_read/write() as generally style. This patch do 1) merge snd_soc_component_read() and snd_soc_component_read32() 2) it uses soc_component_err() when error case (easy to notice) 3) keeps read32 for now by #define 4) update snd_soc_component_read() for all drivers Because _read() user drivers are not too many, this patch changes all user drivers.

2020-04-29ASoC: fsl_easrc: mark PM functions __maybe_unusedArnd Bergmann
ifdefs are hard, and in this driver the suspend/resume functions are the only callers of some other helpers that trigger a harmless warning when CONFIG_PM is disabled: sound/soc/fsl/fsl_easrc.c:1807:12: warning: 'fsl_easrc_get_firmware' defined but not used [-Wunused-function] 1807 | static int fsl_easrc_get_firmware(struct fsl_asrc *easrc) | ^~~~~~~~~~~~~~~~~~~~~~ sound/soc/fsl/fsl_easrc.c:303:12: warning: 'fsl_easrc_resampler_config' defined but not used [-Wunused-function] 303 | static int fsl_easrc_resampler_config(struct fsl_asrc *easrc) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ Remove the #ifdef and just mark the callers as __maybe_unused to suppress the warnings altogether.

EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module found on i.MX8MN. It is different with old ASRC module. The primary features for the EASRC are as follows: - 4 Contexts - groups of channels with an independent time base - Fully independent and concurrent context control - Simultaneous processing of up to 32 audio channels - Programmable filter charachteristics for each context - 32, 24, 20, and 16-bit fixed point audio sample support - 32-bit floating point audio sample support - 8kHz to 384kHz sample rate - 1/16 to 8x sample rate conversion ratio Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com> Signed-off-by: Cosmin-Gabriel Samoila <cosmin.samoila@nxp.com> Acked-by: Nicolin Chen <nicoleotsuka@gmail.com> Link: https://lore.kernel.org/r/260d7a9fbddf9fa90760d30095df60a4c25fd0a1.1587038908.git.shengjiu.wang@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>
