[PATCH v5 0/7] Audio Graph Updates
by Sameer Pujar 10 Nov '20

10 Nov '20

This series is a prepraration for using generic graph driver for Tegra210 audio. Tegra audio graph series will be sent in a separate series because it has some dependency over other series for documentation work. This series can focus on the generic ASoC driver updates. Below are the summary of changes done. * Support multiple instances of a component. For example there can be multiple I2S devices which can use the same component driver. * Support open platforms with empty Codec endpoint. Customers can plug their own HW and can populate codec endpoint. * In a component model there can be many components which can be connected together. In such cases Identify no-pcm DPCM DAI links which can be used in BE<->BE connections. * Expose structures or helpers to be re-used by other similar graph drivers. The series is based on following references where DPCM usgae for Tegra Audio and simple-card driver proposal were discussed. * https://lkml.org/lkml/2020/4/30/519 (DPCM for Tegra) * https://lkml.org/lkml/2020/6/27/4 (simple-card driver) Changelog ========= v4 -> v5 -------- * No changes in the core/audio-graph driver patches which are part of the current series. * Dropped Tegra audio patches and doc patches. This will be sent separately once the doc depdendencies are resolved. v3 -> v4 -------- * Added new patches to convert graph.txt and audio-graph-card.txt to corresponding json-schema files. Later these references are used in Tegra audio graph schema. * AHUB component binding docs are updated to reflect the usage of ports/port/endpoint * More common stuff is moved into graph_parse_of() and this is used by both generic and Tegra audio graph. * DT binding for Tegra audio graph is updated to included "ports { }" * As per the suggestion 'void *data' member is dropped from 'asoc_simple_priv' and instead container method is used to maintain required custom data internal to Tegra audio graph. v2 -> v3 -------- * Dropped new compatible addition in generic graph driver after reviewing it with Morimoto-san. Instead added Tegra audio graph driver and new compatibles are added in the same. * Added new patches to expose new members for customization in audio graph driver. * Added new patch for Tegra audio graph driver and related documentation. * Minor change in below commit where mutex version of helper is used "ASoC: audio-graph: Identify 'no_pcm' DAI links for DPCM" * DT binding is updated to use the newly exposed compatibles * No changes in other patches v1 -> v2 -------- * Re-organized ports/endpoints description for ADMAIF and XBAR. Updated DT patches accordingly. * After above change, multiple Codec endpoint support is not required and hence dropped for now. This will be considered separately if at all required in future. * Re-ordered patches in the series.

[PATCH] ASoC: qcom: common: Fix refcounting in qcom_snd_parse_of()
by Dan Carpenter 10 Nov '20

10 Nov '20

There are two issues in this function. 1) We can't drop the refrences on "cpu", "codec" and "platform" before we take the reference. This doesn't cause a problem on the first iteration because those pointers start as NULL so the of_node_put() is a no-op. But on the subsequent iterations, it will lead to a use after free. 2) If the devm_kzalloc() allocation failed then the code returned directly instead of cleaning up.

[PATCH v2 0/2] ASoC: soc-compress: tidyup STREAM vs COMPRESS
by Kuninori Morimoto 10 Nov '20

10 Nov '20

Hi Mark These are v2 of tidyup patch-set for SNDRV_PCM_STREAM_xxx and SND_COMPRESS_xxx. soc-compress is using both SNDRV_PCM_STREAM_xxx and SND_COMPRESS_xxx, but mixed use. This is confusable, but no problem. Because these are defined as UAPI and are using same value. This patch-set make sure these are same value. v1 -> v2 - checks COMPRESS vs PCM_STREAM by using BUILD_BUG_ON() Link: https://lore.kernel.org/r/87wnzcfnkk.wl-kuninori.morimoto.gx@renesas.com Kuninori Morimoto (2): ASoC: soc-compress: tidyup STREAM vs COMPRESS ASoC: soc-compress: assume SNDRV_PCM_STREAM_xxx and SND_COMPRESS_xxx are same sound/soc/soc-compress.c | 63 +++++++++++++++------------------------- 1 file changed, 23 insertions(+), 40 deletions(-) -- 2.25.1

This series of patches adds support for Mediatek AFE for MT8192 SoC. At the same time, the calibration function of MT6359 is completed with real machine driver. The patch is based on broonie tree "for-next" branch. Change since v3: - use normal conditional statements to improve legiblity in [v3,3/9] - remove mtk_i2s_hd_en_event as there's trace in the core - impove mt8192_i2s_enum and mt8192_adda_enum Change since v2: - split the dai driver files as a separate patch - fix dt-bindings to GPL-2.0-only License - remove unnecessary preperty descriptions such as 'maxItems' Change since v1: - fixed some typos related to dt-bindings in [v1,3/5] and [v1,5/5] - add vendor prefix to the properties, such as "mediatek,apmixedsys" - add a dependency description to indicate the required header files Jiaxin Yu (9): ASoC: mediatek: mt6359: add the calibration functions ASoC: mediatek: mt8192: add platform driver ASoC: mediatek: mt8192: support i2s in platform driver ASoC: mediatek: mt8192: support adda in platform driver ASoC: mediatek: mt8192: support pcm in platform driver ASoC: mediatek: mt8192: support tdm in platform driver dt-bindings: mediatek: mt8192: add audio afe document ASoC: mediatek: mt8192: add machine driver with mt6359, rt1015 and rt5682 dt-bindings: mediatek: mt8192: add mt8192-mt6358-rt1015-rt5682 document .../bindings/sound/mt8192-afe-pcm.yaml | 100 + .../sound/mt8192-mt6359-rt1015-rt5682.yaml | 42 + sound/soc/codecs/mt6359.c | 110 + sound/soc/codecs/mt6359.h | 7 + sound/soc/mediatek/Kconfig | 23 + sound/soc/mediatek/Makefile | 1 + sound/soc/mediatek/common/mtk-afe-fe-dai.c | 13 +- sound/soc/mediatek/common/mtk-base-afe.h | 1 + sound/soc/mediatek/mt8192/Makefile | 16 + sound/soc/mediatek/mt8192/mt8192-afe-clk.c | 669 ++++ sound/soc/mediatek/mt8192/mt8192-afe-clk.h | 244 ++ sound/soc/mediatek/mt8192/mt8192-afe-common.h | 170 + .../soc/mediatek/mt8192/mt8192-afe-control.c | 163 + sound/soc/mediatek/mt8192/mt8192-afe-gpio.c | 306 ++ sound/soc/mediatek/mt8192/mt8192-afe-gpio.h | 19 + sound/soc/mediatek/mt8192/mt8192-afe-pcm.c | 2389 +++++++++++++ sound/soc/mediatek/mt8192/mt8192-dai-adda.c | 1471 ++++++++ sound/soc/mediatek/mt8192/mt8192-dai-i2s.c | 2110 +++++++++++ sound/soc/mediatek/mt8192/mt8192-dai-pcm.c | 409 +++ sound/soc/mediatek/mt8192/mt8192-dai-tdm.c | 778 ++++ .../mediatek/mt8192/mt8192-interconnection.h | 65 + .../mt8192/mt8192-mt6359-rt1015-rt5682.c | 1058 ++++++ sound/soc/mediatek/mt8192/mt8192-reg.h | 3131 +++++++++++++++++ 23 files changed, 13291 insertions(+), 4 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/mt8192-afe-pcm.yaml create mode 100644 Documentation/devicetree/bindings/sound/mt8192-mt6359-rt1015-rt5682.yaml create mode 100644 sound/soc/mediatek/mt8192/Makefile create mode 100644 sound/soc/mediatek/mt8192/mt8192-afe-clk.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-afe-clk.h create mode 100644 sound/soc/mediatek/mt8192/mt8192-afe-common.h create mode 100644 sound/soc/mediatek/mt8192/mt8192-afe-control.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-afe-gpio.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-afe-gpio.h create mode 100644 sound/soc/mediatek/mt8192/mt8192-afe-pcm.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-dai-adda.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-dai-i2s.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-dai-pcm.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-dai-tdm.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-interconnection.h create mode 100644 sound/soc/mediatek/mt8192/mt8192-mt6359-rt1015-rt5682.c create mode 100644 sound/soc/mediatek/mt8192/mt8192-reg.h -- 2.18.0

[PATCH v3 0/9] slab: provide and use krealloc_array()
by Bartosz Golaszewski 10 Nov '20

10 Nov '20

From: Bartosz Golaszewski <bgolaszewski(a)baylibre.com> Andy brought to my attention the fact that users allocating an array of equally sized elements should check if the size multiplication doesn't overflow. This is why we have helpers like kmalloc_array(). However we don't have krealloc_array() equivalent and there are many users who do their own multiplication when calling krealloc() for arrays. This series provides krealloc_array() and uses it in a couple places. A separate series will follow adding devm_krealloc_array() which is needed in the xilinx adc driver. v1 -> v2: - added a kernel doc for krealloc_array() - mentioned krealloc et al in the docs - collected review tags v2 -> v3: - add a patch improving krealloc()'s kerneldoc - fix a typo - improve .rst doc - tweak line breaks Bartosz Golaszewski (9): mm: slab: clarify krealloc()'s behavior with __GFP_ZERO mm: slab: provide krealloc_array() ALSA: pcm: use krealloc_array() vhost: vringh: use krealloc_array() pinctrl: use krealloc_array() edac: ghes: use krealloc_array() drm: atomic: use krealloc_array() hwtracing: intel: use krealloc_array() dma-buf: use krealloc_array() Documentation/core-api/memory-allocation.rst | 4 ++++ drivers/dma-buf/sync_file.c | 3 +-- drivers/edac/ghes_edac.c | 4 ++-- drivers/gpu/drm/drm_atomic.c | 3 ++- drivers/hwtracing/intel_th/msu.c | 2 +- drivers/pinctrl/pinctrl-utils.c | 2 +- drivers/vhost/vringh.c | 3 ++- include/linux/slab.h | 18 ++++++++++++++++++ mm/slab_common.c | 6 +++--- sound/core/pcm_lib.c | 4 ++-- 10 files changed, 36 insertions(+), 13 deletions(-) -- 2.29.1
