[PATCH v2] ASoC: qcom: lpass-cpu: Remove bit clock state check
by Srinivasa Rao Mandadapu 28 Jan '21

28 Jan '21

No need of BCLK state maintenance from driver side as clock_enable and clk_disable API's maintaing state counter. One of the major issue was spotted when Headset jack inserted while playback continues, due to same PCM device node opens twice for playaback/capture and closes once for capture and playback continues. It can resolve the errors in such scenarios.

[PATCH] ASoC: ti: Allocate dais dynamically for TDM and audio graph card
by Pavel Machek 28 Jan '21

28 Jan '21

From: Tony Lindgren <tony(a)atomide.com> We can have multiple connections on a single McBSP instance configured with audio graph card when using TDM (Time Division Multiplexing). Let's allow that by configuring dais dynamically. See Documentation/devicetree/bindings/sound/audio-graph-card.txt and Documentation/devicetree/bindings/graph.txt for more details for multiple endpoints. I've tested this with droid4 where cpcap pmic and modem voice are both both wired to mcbsp3. I've also tested this on droid4 both with and without the pending modem audio codec driver that is waiting for n_gsm serdev dependencies to clear.

[PATCH 1/3] ASoC: SOF: allow soundwire use desc->default_fw_filename
by Kai Vehmanen 27 Jan '21

27 Jan '21

From: Libin Yang <libin.yang(a)intel.com> The old code always uses sof_fw_filename in struct snd_soc_acpi_mach as the firmware name. However, firmware name should depend on the platform instead of the machine. For example, different machines may use the same soundwire link topology, but they are using the different firmware. In this case, it's hard to determine in struct snd_soc_acpi_mach which firmware it should use.

[PATCH] ASoC: siu: Fix build error by a wrong const prefix
by Takashi Iwai 27 Jan '21

27 Jan '21

A const prefix was put wrongly in the middle at the code refactoring commit 932eaf7c7904 ("ASoC: sh: siu_pcm: remove snd_pcm_ops"), which leads to a build error as: sound/soc/sh/siu_pcm.c:546:8: error: expected '{' before 'const' Also, another inconsistency is that the declaration of siu_component misses the const prefix. This patch corrects both failures.

[PATCH v2 1/2] ASoC: soc-component: add snd_soc_component_read/write_field()
by Srinivas Kandagatla 27 Jan '21

27 Jan '21

It's often the case that we would write or read a particular field in register. With the current soc_component apis, reading a particular field in register would involve first read the register and then perform shift operations. Ex: to read from a field mask of 0xf0 val = snd_soc_component_read(component, reg); field = ((val & 0xf0) >> 0x4); This is sometimes prone to errors and code become less readable! With this new api we could just do field = snd_soc_component_read_field(component, reg, 0xf0); this makes it bit simple, easy to write and less error prone! This also applies to writing! There are various places in kernel which provides such field interfaces however soc_component seems to be missing this. This patch is inspired by FIELD_GET/FIELD_PREP macros in include/linux/bitfield.h Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> --- Changes since v1: - removed open coding and call read and update_bits - made soc_component_field_shift an inline function include/sound/soc-component.h | 6 ++++ sound/soc/soc-component.c | 53 +++++++++++++++++++++++++++++++++++ 2 files changed, 59 insertions(+) diff --git a/include/sound/soc-component.h b/include/sound/soc-component.h index 0bce41fefd30..5b47768222b7 100644 --- a/include/sound/soc-component.h +++ b/include/sound/soc-component.h @@ -353,6 +353,12 @@ int snd_soc_component_test_bits(struct snd_soc_component *component, unsigned int reg, unsigned int mask, unsigned int value); +unsigned int snd_soc_component_read_field(struct snd_soc_component *component, + unsigned int reg, unsigned int mask); +int snd_soc_component_write_field(struct snd_soc_component *component, + unsigned int reg, unsigned int mask, + unsigned int val); + /* component wide operations */ int snd_soc_component_set_sysclk(struct snd_soc_component *component, int clk_id, int source, diff --git a/sound/soc/soc-component.c b/sound/soc/soc-component.c index 760523382f3c..361a79d655e3 100644 --- a/sound/soc/soc-component.c +++ b/sound/soc/soc-component.c @@ -34,6 +34,18 @@ static inline int _soc_component_ret(struct snd_soc_component *component, return ret; } +static inline int soc_component_field_shift(struct snd_soc_component *component, + unsigned int mask) +{ + if (!mask) { + dev_err(component->dev, "ASoC: error field mask is zero for %s\n", + component->name); + return 0; + } + + return (__builtin_ffs(mask) - 1); +} + /* * We might want to check substream by using list. * In such case, we can update these macros. @@ -839,6 +851,47 @@ int snd_soc_component_update_bits_async(struct snd_soc_component *component, } EXPORT_SYMBOL_GPL(snd_soc_component_update_bits_async); +/** + * snd_soc_component_read_field() - Read register field value + * @component: Component to read from + * @reg: Register to read + * @mask: mask of the register field + * + * Return: read value of register field. + */ +unsigned int snd_soc_component_read_field(struct snd_soc_component *component, + unsigned int reg, unsigned int mask) +{ + unsigned int val; + + val = snd_soc_component_read(component, reg); + + val = (val & mask) >> soc_component_field_shift(component, mask); + + return val; +} +EXPORT_SYMBOL_GPL(snd_soc_component_read_field); + +/** + * snd_soc_component_write_field() - write to register field + * @component: Component to write to + * @reg: Register to write + * @mask: mask of the register field to update + * @val: value of the field to write + * + * Return: 1 for change, otherwise 0. + */ +int snd_soc_component_write_field(struct snd_soc_component *component, + unsigned int reg, unsigned int mask, + unsigned int val) +{ + + val = (val << soc_component_field_shift(component, mask)) & mask; + + return snd_soc_component_update_bits(component, reg, mask, val); +} +EXPORT_SYMBOL_GPL(snd_soc_component_write_field); + /** * snd_soc_component_async_complete() - Ensure asynchronous I/O has completed * @component: Component for which to wait -- 2.21.0
