[PATCH v2 0/2] ASoC: qcom: common: Parse auxiliary devices from device tree
by Stephan Gerhold 08 Sep '20

08 Sep '20

In some cases we need to probe additional audio components that do not appear as part of the DAI links specified in the device tree. Examples for this are auxiliary devices such as analog amplifiers or codecs. The ASoC core provides a way to probe these components by adding them to snd_soc_card->aux_dev. This patch set allows specifying them in the device tree through a new "aux-devs" property. v1: https://lore.kernel.org/linux-arm-msm/20200819091533.2334-1-stephan@gerhold… Changes in v2: - Fix value type in device tree bindings: aux-devs should be array of phandles without any arguments, so change <phandles with arguments> -> <array of phandles> Stephan Gerhold (2): ASoC: dt-bindings: qcom: Document "aux-devs" property ASoC: qcom: common: Parse auxiliary devices from device tree .../devicetree/bindings/sound/qcom,apq8016-sbc.txt | 7 +++++++ Documentation/devicetree/bindings/sound/qcom,apq8096.txt | 8 ++++++++ Documentation/devicetree/bindings/sound/qcom,sdm845.txt | 8 ++++++++ sound/soc/qcom/common.c | 4 ++++ 4 files changed, 27 insertions(+) -- 2.28.0

[PATCH 00/16] Add Allwinner H3/H5/H6/A64 HDMI audio
by Clément Péron 04 Sep '20

04 Sep '20

Hi, This a merge of serie: - Add Add H6 I2S support https://patchwork.kernel.org/cover/11497007/ - Add Allwinner H3/H5/A64 HDMI audio https://patchwork.kernel.org/cover/11510511/ I merge both serie because there is a similar issue regarding the I2S polarity. This need to be investigated under a scope and see if the comment is still true for Allwinner H6 and previous SoC. LibreElec team found that we have to introduce the "simple-audio-card,frame-inversion" property with recent mainline change. In order to make HDMI audio work. Maybe the I2S polarity is good or maybe the silicium has an issue but not present for HDMI I2S or not present in TDM mode... I cannot do it myself, so if someone want to to do it please feel free. Regarding the discussion we had here: https://patchwork.kernel.org/patch/11510521/ I didn't switch to generic hdmi card-name and used name like: sun8i-h3-hdmi, sun50i-h6-hdmi, etc.... Despite this wrong comment the rest of the serie introduce some fix that should be merged even if it's without the H6 support.

[PATCH v4 0/3] ASoC: soundwire: fix port_ready[] dynamic allocation
by Bard Liao 03 Sep '20

03 Sep '20

The existing code allocates memory for the total number of ports. This only works if the ports are contiguous, but will break if e.g. a Devices uses port0, 1, and 14. The port_ready[] array would contain 3 elements, which would lead to an out-of-bounds access. Conversely in other cases, the wrong port index would be used leading to timeouts on prepare. This can be fixed by allocating for the worst-case of 15 ports (DP0..DP14). In addition since the number is now fixed, we can use an array instead of a dynamic allocation. Changes in v4: - Reorder the patches order to allow bisect. Changes in v3: - Add ASoC tag in the cover letter title. - Edit the title and commit message of the third patch for better understanding. Changes in v2: - Split patches into sdw and asoc patches. Please note that "soundwire: fix port_ready[] dynamic allocation in mipi_disco" and "ASoC: codecs: fix port_ready[] dynamic allocation in ASoC codecs" should be merged at the same time.

a saner API for allocating DMA addressable pages
by Christoph Hellwig 03 Sep '20

03 Sep '20

Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported. I'm still a little unsure about the API naming, as alloc_pages sort of implies a struct page return value, but we return a kernel virtual address. The other alternative would be to name the API dma_alloc_noncoherent, but the whole non-coherent naming seems to put people off. As a follow up I plan to move the implementation of the DMA_ATTR_NO_KERNEL_MAPPING flag over to this framework as well, given that is also is a fundamentally non coherent allocation. The replacement for that flag would then return a struct page, as it is allowed to actually return pages without a kernel mapping as the name suggested (although most of the time they will actually have a kernel mapping..) In addition to the conversions of the existing non-coherent DMA users the last three patches also convert the DMA coherent allocations in the NVMe driver to use this new framework through a dmapool addition. This was both to give me a good testing vehicle, but also because it should speed up the NVMe driver on platforms with non-coherent DMA nicely, without a downside on platforms with cache coherent DMA.
