[alsa-devel] [PATCH v5 00/12] AC97 device/driver model revamp
by Robert Jarzmik 04 Sep '17

04 Sep '17

Hi Lars, Mark, Charles, Lee, This is a minor revision after v4, mainly reviews from Takashi, Charles. I extracted the diff from the v3 of sound/ac97 which is in [1] for easier spotting of what has globally changed. I tentatively kept your Ack Charles for patch 11/12, please shout if you disagree (there is an #ifdef added). I would still need a review from you, Lee, for the mfd patch (patch 6/12). Happy review. -- Robert Robert Jarzmik (12): ALSA: ac97: split out the generic ac97 registers ALSA: ac97: add an ac97 bus ASoC: add new ac97 bus support ASoC: arm: make pxa2xx-ac97-lib ac97 codec agnostic Input: wm97xx: split out touchscreen registering mfd: wm97xx-core: core support for wm97xx Codec Input: wm97xx: add new AC97 bus support ASoC: wm9713: add ac97 new bus support ASoC: wm9712: add ac97 new bus support ASoC: wm9705: add private structure ASoC: wm9705: add ac97 new bus support ASoC: pxa: switch to new ac97 bus support drivers/input/touchscreen/Kconfig | 2 +- drivers/input/touchscreen/wm97xx-core.c | 252 ++++++++++----- drivers/mfd/Kconfig | 15 + drivers/mfd/Makefile | 1 + drivers/mfd/wm97xx-core.c | 405 ++++++++++++++++++++++++ include/linux/mfd/wm97xx.h | 31 ++ include/sound/ac97/codec.h | 118 +++++++ include/sound/ac97/compat.h | 20 ++ include/sound/ac97/controller.h | 85 +++++ include/sound/ac97/regs.h | 262 ++++++++++++++++ include/sound/ac97_codec.h | 239 +------------- include/sound/pxa2xx-lib.h | 15 +- sound/Kconfig | 2 + sound/Makefile | 1 + sound/ac97/Kconfig | 19 ++ sound/ac97/Makefile | 8 + sound/ac97/ac97_core.h | 16 + sound/ac97/bus.c | 539 ++++++++++++++++++++++++++++++++ sound/ac97/codec.c | 15 + sound/ac97/snd_ac97_compat.c | 108 +++++++ sound/arm/Kconfig | 1 - sound/arm/pxa2xx-ac97-lib.c | 37 ++- sound/arm/pxa2xx-ac97.c | 35 ++- sound/soc/codecs/Kconfig | 9 +- sound/soc/codecs/wm9705.c | 61 ++-- sound/soc/codecs/wm9712.c | 39 ++- sound/soc/codecs/wm9713.c | 39 ++- sound/soc/pxa/Kconfig | 5 +- sound/soc/pxa/pxa2xx-ac97.c | 46 ++- 29 files changed, 2011 insertions(+), 414 deletions(-) create mode 100644 drivers/mfd/wm97xx-core.c create mode 100644 include/linux/mfd/wm97xx.h create mode 100644 include/sound/ac97/codec.h create mode 100644 include/sound/ac97/compat.h create mode 100644 include/sound/ac97/controller.h create mode 100644 include/sound/ac97/regs.h create mode 100644 sound/ac97/Kconfig create mode 100644 sound/ac97/Makefile create mode 100644 sound/ac97/ac97_core.h create mode 100644 sound/ac97/bus.c create mode 100644 sound/ac97/codec.c create mode 100644 sound/ac97/snd_ac97_compat.c -- 2.11.0 [1] sound diff from last revision (git diff submit/ac97-3..submit/ac97-4 sound/ac97 include/sound/ac97) diff --git a/include/sound/ac97/compat.h b/include/sound/ac97/compat.h index d876464bf7e4..1351cba40048 100644 --- a/include/sound/ac97/compat.h +++ b/include/sound/ac97/compat.h @@ -13,7 +13,6 @@ #define AC97_COMPAT_H #include <sound/ac97_codec.h> -#include <sound/soc.h> struct snd_ac97 *snd_ac97_compat_alloc(struct ac97_codec_device *adev);

[alsa-devel] [PATCH v4 00/12] AC97 device/driver model revamp
by Robert Jarzmik 04 Sep '17

04 Sep '17

Hi Lars, Mark, Charles, Lee, This is a minor revision after v3, mainly reviews from Takashi, Charles. I did more extensive testing of load/unload of the whole serie, and apart from a bug in wm97xx-core in touchscreen tree (for a which a patch will be sent apart), it seems to work properly. I extracted the diff from the v3 of sound/ac97 which is in [1] for easier spotting of what has globally changed. I would still need a review from you, Lee, for the mfd patch (patch 6/12). Happy review. -- Robert Robert Jarzmik (12): ALSA: ac97: split out the generic ac97 registers ALSA: ac97: add an ac97 bus ASoC: add new ac97 bus support ASoC: arm: make pxa2xx-ac97-lib ac97 codec agnostic Input: wm97xx: split out touchscreen registering mfd: wm97xx-core: core support for wm97xx Codec Input: wm97xx: add new AC97 bus support ASoC: wm9713: add ac97 new bus support ASoC: wm9712: add ac97 new bus support ASoC: wm9705: add private structure ASoC: wm9705: add ac97 new bus support ASoC: pxa: switch to new ac97 bus support drivers/input/touchscreen/Kconfig | 2 +- drivers/input/touchscreen/wm97xx-core.c | 252 ++++++++++----- drivers/mfd/Kconfig | 15 + drivers/mfd/Makefile | 1 + drivers/mfd/wm97xx-core.c | 405 ++++++++++++++++++++++++ include/linux/mfd/wm97xx.h | 31 ++ include/sound/ac97/codec.h | 118 +++++++ include/sound/ac97/compat.h | 21 ++ include/sound/ac97/controller.h | 84 +++++ include/sound/ac97/regs.h | 262 +++++++++++++++ include/sound/ac97_codec.h | 239 +------------- include/sound/pxa2xx-lib.h | 15 +- sound/Kconfig | 2 + sound/Makefile | 1 + sound/ac97/Kconfig | 19 ++ sound/ac97/Makefile | 8 + sound/ac97/ac97_core.h | 10 + sound/ac97/bus.c | 542 ++++++++++++++++++++++++++++++++ sound/ac97/codec.c | 15 + sound/ac97/snd_ac97_compat.c | 105 +++++++ sound/arm/Kconfig | 1 - sound/arm/pxa2xx-ac97-lib.c | 37 ++- sound/arm/pxa2xx-ac97.c | 35 ++- sound/soc/codecs/Kconfig | 9 +- sound/soc/codecs/wm9705.c | 59 ++-- sound/soc/codecs/wm9712.c | 37 ++- sound/soc/codecs/wm9713.c | 39 ++- sound/soc/pxa/Kconfig | 5 +- sound/soc/pxa/pxa2xx-ac97.c | 46 ++- 29 files changed, 2001 insertions(+), 414 deletions(-) create mode 100644 drivers/mfd/wm97xx-core.c create mode 100644 include/linux/mfd/wm97xx.h create mode 100644 include/sound/ac97/codec.h create mode 100644 include/sound/ac97/compat.h create mode 100644 include/sound/ac97/controller.h create mode 100644 include/sound/ac97/regs.h create mode 100644 sound/ac97/Kconfig create mode 100644 sound/ac97/Makefile create mode 100644 sound/ac97/ac97_core.h create mode 100644 sound/ac97/bus.c create mode 100644 sound/ac97/codec.c create mode 100644 sound/ac97/snd_ac97_compat.c -- 2.11.0 [1] sound diff from last revision (git diff submit/ac97-2..submit/ac97-3 sound/ac97 include/sound/ac97) diff --git a/sound/ac97/bus.c b/sound/ac97/bus.c index 7cda8175341e..af618a0e89cb 100644 --- a/sound/ac97/bus.c +++ b/sound/ac97/bus.c @@ -76,7 +76,6 @@ static void ac97_codec_release(struct device *dev) adev = to_ac97_device(dev); ac97_ctrl = adev->ac97_ctrl; ac97_ctrl->codecs[adev->num] = NULL; - sysfs_remove_link(&dev->kobj, "ac97_controller"); kfree(adev); } @@ -269,8 +268,29 @@ static const struct attribute_group *ac97_adapter_groups[] = { NULL, }; +static void ac97_del_adapter(struct ac97_controller *ac97_ctrl) +{ + mutex_lock(&ac97_controllers_mutex); + ac97_ctrl_codecs_unregister(ac97_ctrl); + list_del(&ac97_ctrl->controllers); + mutex_unlock(&ac97_controllers_mutex); + + device_unregister(&ac97_ctrl->adap); +} + +static void ac97_adapter_release(struct device *dev) +{ + struct ac97_controller *ac97_ctrl; + + ac97_ctrl = to_ac97_controller(dev); + idr_remove(&ac97_adapter_idr, ac97_ctrl->nr); + dev_dbg(&ac97_ctrl->adap, "adapter unregistered by %s\n", + dev_name(ac97_ctrl->parent)); +} + static const struct device_type ac97_adapter_type = { .groups = ac97_adapter_groups, + .release = ac97_adapter_release, }; static int ac97_add_adapter(struct ac97_controller *ac97_ctrl) @@ -298,16 +318,6 @@ static int ac97_add_adapter(struct ac97_controller *ac97_ctrl) return ret; } -static void ac97_del_adapter(struct ac97_controller *ac97_ctrl) -{ - mutex_lock(&ac97_controllers_mutex); - ac97_ctrl_codecs_unregister(ac97_ctrl); - list_del(&ac97_ctrl->controllers); - idr_remove(&ac97_adapter_idr, ac97_ctrl->nr); - mutex_unlock(&ac97_controllers_mutex); - put_device(&ac97_ctrl->adap); -} - /** * snd_ac97_controller_register - register an ac97 controller * @ops: the ac97 bus operations @@ -508,7 +518,7 @@ static int ac97_bus_remove(struct device *dev) } static struct bus_type ac97_bus_type = { - .name = "ac97", + .name = "ac97bus", .dev_groups = ac97_dev_groups, .match = ac97_bus_match, .pm = &ac97_pm, @@ -522,5 +532,11 @@ static int __init ac97_bus_init(void) } subsys_initcall(ac97_bus_init); +static void __exit ac97_bus_exit(void) +{ + bus_unregister(&ac97_bus_type); +} +module_exit(ac97_bus_exit); + MODULE_LICENSE("GPL"); MODULE_AUTHOR("Robert Jarzmik <robert.jarzmik(a)free.fr>");

[alsa-devel] [PATCH 0/6 v3] Add ASoC support for AMD Stoney APUs
by Alex Deucher 01 Sep '17

01 Sep '17

This patch set updates the AMD GPU and Audio CoProcessor (ACP) audio drivers and the designware i2s driver for Stoney (ST). ST is an APU similar to Carrizo (CZ) which already has ACP audio support. The i2s controller and ACP audio DMA engine are part of the GPU and both need updating so I would like to upstream the whole patch set via one tree if possible. The current code is based on drm-next, but I'm happy to rebase on whatever tree this ends up going through if there are any problems applying. These patches touch both audio and drm. The entire patch set can be viewed here: https://cgit.freedesktop.org/~agd5f/linux/log/?h=stoney_acp2 Thanks! Alex v2: - Patch 1 is already applied to the audio tree, just including it for completeness since it's required for this patch set and it's not yet in the drm tree. - New patch to share asic types between gpu and audio drivers - ACPI ID changed for rt5650 machine driver - Integrate feedback on other patches v3: - resend remaining patches that have not been applied yet Akshu Agrawal (2): drm/amdgpu Moving amdgpu asic types to a separate file ASoC: AMD: Add machine driver for cz rt5650 Vijendar Mukunda (4): drm/amd/amdgpu: Added asic_type as ACP DMA driver platform data ASoC: AMD: disabling memory gating in stoney platform ASoC: AMD: DMA driver changes for Stoney Platform ASoC: AMD: Audio buffer related changes for Stoney drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c | 2 + drivers/gpu/drm/amd/include/amd_shared.h | 29 +--- include/drm/amd_asic_type.h | 52 +++++++ sound/soc/amd/Kconfig | 7 + sound/soc/amd/Makefile | 2 + sound/soc/amd/acp-pcm-dma.c | 243 ++++++++++++++++++++++++------- sound/soc/amd/acp-rt5645.c | 210 ++++++++++++++++++++++++++ sound/soc/amd/acp.h | 9 ++ 8 files changed, 472 insertions(+), 82 deletions(-) create mode 100644 include/drm/amd_asic_type.h create mode 100644 sound/soc/amd/acp-rt5645.c -- 2.5.5

[alsa-devel] [PATCH] asoc: make clock direction configurable in asoc-simple
by Vitaly Wool 01 Sep '17

01 Sep '17

Some CPU drivers (e. g. davinci-mcasp) may require the system clock to be configured as OUT, while there's no good way currently to set SND_SOC_CLK_OUT in simple-soc driver if the clock is fixed-rate. This patch makes asoc_simple_card_init_dai() initialize clock to SND_SOCK_CLK_OUT if explicitly stated in the relevant dts file. This change is transparent and doesn't change the default behavior.
