[alsa-devel] [PATCH v4 0/2] ASoC: mt8183: fix audio playback slowly after playback
by Jiaxin Yu 02 Jan '20

02 Jan '20

This series patches add reset controller for MT8183, and audio will use it in machine driver during bootup, they depend on the for-next. v4 changes: 1. Fixed wrong signed-off as correct mail suffix. 2. Fixed patch subject that add patch version. v3 changes: 1. https://patchwork.kernel.org/patch/11164283/ and https://patchwork.kernel.org/patch/11164305/ has been merged. 2. Change the name of mtk_wdt_compatible to mtk_wdt_data. 3. Remove toprgu_reset struct and use mtk_wdt_dev instead. 4. Get the value of sw_rst_num from .h file. 5. Adddd mt2712-resets.h for mt2712. 6. Improve commit message. v2 changes: 1. remove "WIP" that in the title of patches 2. add hyper link for the patch that depends on 3. patchwork list: https://patchwork.kernel.org/cover/11164285/ https://patchwork.kernel.org/patch/11164295/ https://patchwork.kernel.org/patch/11164299/ https://patchwork.kernel.org/patch/11164283/ https://patchwork.kernel.org/patch/11164305/ v1 changes: 1. patchwork list: https://patchwork.kernel.org/cover/11164173/ https://patchwork.kernel.org/patch/11164181/ https://patchwork.kernel.org/patch/11164185/ https://patchwork.kernel.org/patch/11164187/ https://patchwork.kernel.org/patch/11164175/ yong.liang (2): dt-bindings: mediatek: mt8183: Add #reset-cells watchdog: mtk_wdt: mt8183: Add reset controller .../devicetree/bindings/watchdog/mtk-wdt.txt | 10 +- drivers/watchdog/Kconfig | 1 + drivers/watchdog/mtk_wdt.c | 111 +++++++++++++++++- .../reset-controller/mt2712-resets.h | 22 ++++ .../reset-controller/mt8183-resets.h | 15 +++ 5 files changed, 155 insertions(+), 4 deletions(-) create mode 100644 include/dt-bindings/reset-controller/mt2712-resets.h -- 2.18.0

[alsa-devel] [PATCH] ASoC: cs47l92: Simplify error handling code in 'cs47l92_probe()'
by Christophe JAILLET 31 Dec '19

31 Dec '19

If 'madera_init_bus_error_irq()' fails, 'wm_adsp2_remove(&cs47l92->core.adsp[0])' will be called twice. Once in the 'if' block, and once in the error handling path. This is harmless, but one of this call can be axed.

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again. Added resume pm call back to ACP pm ops and also added runtime PM operations for ACP3x PCM platform device. Device will enter into D3 state when there is no activity on audio I2S lines.

[alsa-devel] [PATCH 1/6] ASoC: amd: Refactoring of DAI from DMA driver
by Ravulapati Vishnu vardhan rao 31 Dec '19

31 Dec '19

ASoC: PCM DMA driver should only have dma ops. So Removed all DAI related functionality.Refactoring the PCM DMA diver code.Added new file containing only DAI ops Signed-off-by: Ravulapati Vishnu vardhan rao <Vishnuvardhanrao.Ravulapati(a)amd.com> --- sound/soc/amd/raven/Makefile | 2 + sound/soc/amd/raven/acp3x-i2s.c | 261 ++++++++++++++++++++++++++++++++ sound/soc/amd/raven/acp3x-pcm-dma.c | 292 ++++++------------------------------ sound/soc/amd/raven/acp3x.h | 44 ++++++ 4 files changed, 356 insertions(+), 243 deletions(-) create mode 100644 sound/soc/amd/raven/acp3x-i2s.c diff --git a/sound/soc/amd/raven/Makefile b/sound/soc/amd/raven/Makefile index 108d1ac..62c22b6 100644 --- a/sound/soc/amd/raven/Makefile +++ b/sound/soc/amd/raven/Makefile @@ -2,5 +2,7 @@ # Raven Ridge platform Support snd-pci-acp3x-objs := pci-acp3x.o snd-acp3x-pcm-dma-objs := acp3x-pcm-dma.o +snd-acp3x-i2s-objs := acp3x-i2s.o obj-$(CONFIG_SND_SOC_AMD_ACP3x) += snd-pci-acp3x.o obj-$(CONFIG_SND_SOC_AMD_ACP3x) += snd-acp3x-pcm-dma.o +obj-$(CONFIG_SND_SOC_AMD_ACP3x) += snd-acp3x-i2s.o diff --git a/sound/soc/amd/raven/acp3x-i2s.c b/sound/soc/amd/raven/acp3x-i2s.c new file mode 100644 index 0000000..d9bc0fc --- /dev/null +++ b/sound/soc/amd/raven/acp3x-i2s.c @@ -0,0 +1,261 @@ +// SPDX-License-Identifier: GPL-2.0+ +// +// AMD ALSA SoC PCM Driver +// +//Copyright 2016 Advanced Micro Devices, Inc. + +#include <linux/platform_device.h> +#include <linux/module.h> +#include <linux/err.h> +#include <linux/io.h> +#include <sound/pcm_params.h> +#include <sound/soc.h> +#include <sound/soc-dai.h> +#include <linux/dma-mapping.h> + +#include "acp3x.h" + +#define DRV_NAME "acp3x-i2s" + +static int acp3x_i2s_set_fmt(struct snd_soc_dai *cpu_dai, + unsigned int fmt) +{ + struct i2s_dev_data *adata;

[alsa-devel] [PATCH] ASoC: core: Fix access to uninitialized list heads
by Takashi Iwai 31 Dec '19

31 Dec '19

The error path of soc_new_pcm_runtime() invokes soc_free_pcm_runtime() that may cause a few problems. First off, it calls list_del() for rtd->list that may not be initialized. Similarly, snd_soc_pcm_component_free() traverses over the component list that may not be initialized, either. Such access to the uninitialized list head would lead to either a BUG_ON() or a memory corruption. This patch fixes the access to uninitialized list heads by initializing the list heads properly at the beginning before those error paths.
