[alsa-devel] [PATCH 0/20] ASoC: rsnd: add Synchronous SRC and U/O error salvage support
by Kuninori Morimoto 24 Feb '15

24 Feb '15

Hi Mark. These patches adds [1] Synchronous SRC, [2] under/over run error salvage support to Renesas sound driver. 1) - 16) : prepare cleanup/tidyup for 17) - 19) 17) : Synchronous SRC 18)- 19) : salvage support for under/over run error 20) : cleanup for 18) - 19) Current Renesas sound can use Asynchronous/Synchronous sampling rate convert. Asynchronous sampling rate convert is already supported on upstream. ("feature" is supported, "DT" bindings is not yet supported) 17) adds Synchronous sampling rate convert. Renesas sound has HW bug (?) which switches L/R channel if under/over run error had occurred. 18) - 19) adds salvage supported for it. 20) is cleanup patch which is based on 18)-19) patch Kuninori Morimoto (20): 1. ASoC: rsnd: add .fallback callback 2. ASoC: rsnd: add callback status check method 3. ASoC: rsnd: rsnd_src_ssiu_stop() stops SSIU compulsorily 4. ASoC: rsnd: tidyup PIO/DMA mode settings method 5. ASoC: rsnd: tidyup SSI interrupt enable/disable method 6. ASoC: rsnd: care SSIWSR register in rsnd_ssi_hw_start() 7. ASoC: rsnd: clear status register when HW start 8. ASoC: rsnd: synchronize SSI start/stop sequence between PIO/DMA mode 9. ASoC: rsnd: show master clock rate when ADG probe 10. ASoC: rsnd: move snd_kcontrol_new fucntions to core.c 11. ASoC: rsnd: tidyup rsnd_io_to_runtime() macro 12. ASoC: rsnd: use rsnd_src_convert_rate() once on rsnd_src_set_convert_rate_gen2() 13. ASoC: rsnd: initialize SRC on rsnd_src_init() 14. ASoC: rsnd: set SRC_ROUTE_MODE0 on each rsnd_src_set_convert_rate() 15. ASoC: rsnd: share SSI starting method between PIO/DMA mode 16. ASoC: rsnd: remove un-necessary parameter from rsnd_src_start/stop() 17. ASoC: rsnd: add Synchronous SRC mode 18. ASoC: rsnd: add salvage support for under/over flow error on SSI 19.

[alsa-devel] [PATCH 0/4] ASoC: samsung: clean up references to outdated Kconfig symbols
by Paul Bolle 14 Feb '15

14 Feb '15

A few series of ARM cleanups regarding S5PC100 and S5PV210 were included in v3.17. These series removed these five Kconfig symbols: MACH_AQUILA MACH_GONI MACH_SMDKC100 MACH_SMDKC110 MACH_SMDKV210 This series, done on top of next-20150119, removes the remaining references to those five symbols. (The first two patches are actually resends.) Paul Bolle (4): ASoC: samsung: Remove goni or aquila with the WM8994 ASoC: samsung: Remove PCM support for WM8580 on SMDK ASoC: samsung: MACH_SMDKC100 isn't supported anymore ASoC: samsung: remove outdated Kconfig references sound/soc/samsung/Kconfig | 24 +-- sound/soc/samsung/Makefile | 4 - sound/soc/samsung/goni_wm8994.c | 289 ------------------------------------- sound/soc/samsung/smdk_wm8580pcm.c | 176 ---------------------- 4 files changed, 2 insertions(+), 491 deletions(-) delete mode 100644 sound/soc/samsung/goni_wm8994.c delete mode 100644 sound/soc/samsung/smdk_wm8580pcm.c -- 1.9.3

Commit 28c8331d386a ("ARM: S5PV210: Remove support for board files") removed the Kconfig symbols MACH_GONI and MACH_AQUILA. As a result the dependencies of SND_SOC_GONI_AQUILA_WM8994 can never be met. So remove the unbuildable "SoC I2S Audio support for AQUILA/GONI - WM8994".

[alsa-devel] [PATCH 4/4] ASoC: samsung: remove outdated Kconfig references
by Paul Bolle 07 Feb '15

07 Feb '15

The Kconfig symbols MACH_SMDKC110 and MACH_SMDKV210 were removed in v3.17. But the Kconfig entries for SND_SOC_SAMSUNG_SMDK_WM8580 and SND_SOC_SAMSUNG_SMDK_WM9713 still reference them. Perhaps these references to those removed symbols should be changed into references to an existing symbol (such as MACH_S5PV210_DT). But apparently no one noticed that these references were pointless ever since v3.17. So it seems they can simply be removed. Let's do that now.

Commit b8529ec1c1b0 ("ARM: S5PC100: no more support S5PC100 SoC") removed Kconfig symbol MACH_SMDKC100. But there are still two references to that symbol left. These are now pointless.

[alsa-devel] [PATCH 2/4] ASoC: samsung: Remove PCM support for WM8580 on SMDK
by Paul Bolle 07 Feb '15

07 Feb '15

Commit 28c8331d386a ("ARM: S5PV210: Remove support for board files") removed the Kconfig symbols MACH_SMDKC110 and MACH_SMDKV210. As a result the dependencies of SND_SOC_SMDK_WM8580_PCM can never be met. So remove the unbuildable "SoC PCM Audio support for WM8580 on SMDK".
