[PATCH] ASoC: rsnd: adg: use __clk_get_name() instead of local clk_name[]
by Kuninori Morimoto 28 Nov '22

28 Nov '22

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Current rsnd_adg_clk_dbg_info() is using locak clk_name[] to ndicating clk name, but we don't want to use local clk_name[] everywhere when we support R-Car Gen4 sound to handling non compatible clk naming. This patch uses __clk_get_name() instead of local clk_name[] for it.

[PATCH] ASoC: rt5640: Fix Jack work after system suspend
by Oder Chiou 28 Nov '22

28 Nov '22

We found an corner case in RT5640 codec driver which schedules jack work after system suspend as IRQ was enabled. Due to this, hitting the error as register access happening after suspend as jack worker thread getting scheduled in irq handler. The patch disables the irq during the suspend to prevent the corner case happening.

[PATCH v3 1/9] sound: sdw: Add hw_params to SoundWire config helper function
by Charles Keepax 28 Nov '22

28 Nov '22

The vast majority of the current users of the SoundWire framework have almost identical code for converting from hw_params to SoundWire configuration. Whilst complex devices might require more, it is very likely that most new devices will follow the same pattern. Save a little code by factoring this out into a helper function. Signed-off-by: Charles Keepax <ckeepax(a)opensource.cirrus.com> --- I was a little bit two minds about whether to make this an inline or not, so any thoughts on that would be super welcome. The function does very little, especially given that SNDRV_PCM_STREAM_PLAYBACK == SDW_DATA_DIR_RX so the if is also really just an assignment.

[PATCH v2 00/11] ASoC: dt-bindings: Rework Qualcomm APR/GPR Sound nodes for SM8450
by Krzysztof Kozlowski 28 Nov '22

28 Nov '22

Changes since v1 ================ 1. Patch 2: Keep compatibles in qcom,apr.yaml. 2. Patch 3: New patch. Description =========== Adding sound support for Qualcomm SM8450 SoC (and later for SC8280XP) brought some changes to APR/GPR services bindings. These bindings are part of qcom,apr.yaml: apr-or-gpr-device-node <- qcom,apr.yaml apr-gpr-service@[0-9] <- qcom,apr.yaml service-specific-components <- /schemas/sound/qcom,q6*.yaml The schema for services (apr-gpr-service@[0-9]) was not complete and is still quite not specific. It allows several incorrect combinations, like adding a clock-controller to a APM device. Restricting it would complicate the schema even more. Bringing new support for sound on Qualcomm SM8450 and SC8280XP SoC would grow it as well. Refactor the bindings before extending them for Qualcomm SM8450 SoC.
