[PATCH v2 0/3] ASoC: dt-bindings: Rework audio-graph-port schema
by Rob Herring 01 Apr '21

01 Apr '21

This series refactors the audio-graph-port.yaml schema moving the 'port' node out of the schema and updating to use graph.yaml schema. This allows users to define what each 'port' node is like other graph binding users. v2: - Rebase on ASoC tree Rob Cc: alsa-devel(a)alsa-project.org Cc: linux-tegra(a)vger.kernel.org Cc: Jonathan Hunter <jonathanh(a)nvidia.com> Cc: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Cc: Liam Girdwood <lgirdwood(a)gmail.com> Cc: Lubomir Rintel <lkundrak(a)v3.sk> Cc: Mark Brown <broonie(a)kernel.org> Cc: Masahiro Yamada <yamada.masahiro(a)socionext.com> Cc: Sameer Pujar <spujar(a)nvidia.com> Cc: Thierry Reding <thierry.reding(a)gmail.com> Rob Herring (3): ASoC: dt-bindings: Move port/ports properties out of audio-graph-port.yaml ASoC: dt-bindings: Use OF graph schema ASoC: dt-bindings: socionext: Use audio-graph-port schema .../bindings/sound/audio-graph-port.yaml | 104 ++++++++---------- .../bindings/sound/marvell,mmp-sspa.yaml | 6 +- .../bindings/sound/nvidia,tegra186-dspk.yaml | 11 +- .../sound/nvidia,tegra210-admaif.yaml | 11 +- .../bindings/sound/nvidia,tegra210-ahub.yaml | 11 +- .../bindings/sound/nvidia,tegra210-dmic.yaml | 11 +- .../bindings/sound/nvidia,tegra210-i2s.yaml | 11 +- .../bindings/sound/renesas,rsnd.yaml | 5 +- .../sound/socionext,uniphier-aio.yaml | 8 +- .../sound/socionext,uniphier-evea.yaml | 8 +- 10 files changed, 89 insertions(+), 97 deletions(-) -- 2.27.0

[PATCH] ASoC: Intel: bytcr_rt5640: Add quirk for the Chuwi Hi8 tablet
by Hans de Goede 01 Apr '21

[PATCH v4 0/5] soundwire: add static port map support
by Srinivas Kandagatla 01 Apr '21

01 Apr '21

In some cases, SoundWire device ports are statically mapped to Controller ports during design, however there is no way to expose this information to the controller. Controllers like Qualcomm ones use this info to setup static bandwidth parameters for those ports. A generic port allocation is not possible in this cases! This patch adds a new member m_port_map to SoundWire device so that it can populate the static master port map and share it with controller to be able to setup correct bandwidth parameters. As a user of this feature this patchset also adds new bindings for wsa881x smart speaker which has 4 ports which are statically mapped to the 3 output and 1 input port of the controller. Tested it on DB845c and SM8250 MTP. thanks, srini Changes since v3: - updated kernel doc for more clarity on m_port_map Srinivas Kandagatla (5): soundwire: add static port mapping support soundwire: qcom: update port map allocation bit mask soundwire: qcom: add static port map support ASoC: dt-bindings: wsa881x: add bindings for port mapping ASoC: codecs: wsa881x: add static port map support .../bindings/sound/qcom,wsa881x.yaml | 9 ++++++ drivers/soundwire/qcom.c | 31 +++++++++++++++---- include/linux/soundwire/sdw.h | 2 ++ sound/soc/codecs/wsa881x.c | 7 +++++ 4 files changed, 43 insertions(+), 6 deletions(-) -- 2.21.0

[PATCH][next] soundwire: qcom: Fix a u8 comparison with less than zero
by Colin King 31 Mar '21

31 Mar '21

From: Colin Ian King <colin.king(a)canonical.com> Variable devnum is being checked for a less than zero error return however the comparison will always be false because devnum is an 8 bit unsigned integer. Fix this by making devnum an int. Also there is no need to iniitialize devnum with zero as this value is no read, so remove the redundant assignment.
