[alsa-devel] ASoC : WM5102 Audio Codec needs ACPI support and a baytrail machine driver
by Christian Hartmann 16 Jun '15

16 Jun '15

Hi list, I have a device "Lenovo Yoga 851 F" which have a WM510205 Audio codec on a Baytrail System. I have sent already one patch (spi-pxa2xx) raise num_chipselect by one, which fixes to bind the arizona WM5102 codec as a spi slave attachted on a pxa2xx spi master device. I have tried several times and added the ACPI id "WM510205" to the arizona-spi.c driver. The ACPI ID is extracted from the DSDT.dsl of this machine. But unfortunately it fails and I got only a NULL pointer deference error in arizona_spi_probe(). I want to request ACPI support for this device and I cannot fix currently the NULL pointer. I do not know yet, if I have to add this ACPI id to the arizona-spi driver (sure, thats what I am trying and failing) or to the NEW baytrail machine driver. In this case it should be the bytcr_wm5102.c and byt-wm5102.c, which does not exists yet. I have a branched tovalds/master and added (my first attempt) the above mentioned machine driver on a local branch. The result is only a dsp boot timeout error. Any help, ideas, hints, patches to try would be appreciate sincerely yours Christian Hartmann a snap of the dsdt Device (LPEA) { Name (_ADR, Zero) // _ADR: Address Name (_HID, "80860F28" /* Intel SST Audio DSP */) // _HID: Hardware ID Name (_CID, "80860F28" /* Intel SST Audio DSP */) // _CID: Compatible ID Name (_DDN, "Intel(R) Low Power Audio Controller - 80860F28") // _DDN: DOS Device Name Name (_SUB, "17AA7004") // _SUB: Subsystem ID Name (_UID, One) // _UID: Unique ID Name (_DEP, Package (0x01) // _DEP: Dependencies { ^SPI1.AUDI }) ... ...

[alsa-devel] [PATCH v2 0/3] ASoC: Mediatek: Add support for MT8173 SOC
by Koro Chen 16 Jun '15

16 Jun '15

This adds basic support for the Mediatek AFE (Audio Front End) unit of MT8173. This patch is based on Linux 4.1-rc1 and Sascha's SCPSYS power patch [1]. The AFE unit comprises several memory interfaces that communicate with CPU, a multi input multi output digital audio interconnect, and several external interfaces (e.g. I2S). [1] https://lkml.org/lkml/2015/6/9/172 changes since v1: - change Kconfig to tristate - remove unnecessary !! in the platform driver - let MODULE_DEVICE_TABLE follow the table - remove regulators from machine drivers changes since RFC: - Use DPCM to model AFE AFE memory interfaces such as DL1, VUL are modeled as frontend DAIs, and AFE IOs such as I2S, HDMI are backend DAIs. Which memif and IO to be used can be set in the machine driver. There is no need to indicate this in dts anymore so include/dt-bindings/sound/mtk-afe.h is removed. AFE connections are represented by DAPM widgets and routes, and set connection APIs/tables are no longer required. (mtk-afe-connection.c and mtk-afe-connection.h are removed)

Hi Mark These are prepare for MIXer support for Renesas sound card. Each Renesas sound mod (= SSI/SRC/DVC) might be called from many paths if it supports MIXer. In such case, mod <-> stream is no longer 1:1 relationship. this patch set don't use rsnd_mod_to_io() as prepare for MIXer support 1) - 2) bugfix patch for PIO mode. These are not critical bug since no platform is using PIO mode. 3) - 10) cleanup for DPCM related code for MIXer support 11) - 21) remove rsnd_mod_to_io() from Renesas sound driver Kuninori Morimoto (21): 1) ASoC: rsnd: don't care under/over run error when PIO 2) ASoC: rsnd: don't call snd_pcm_period_elapsed() under spin lock 3) ASoC: rsrc-card: used "fe.xxx"/"be.xxx" name for dai_link 4) ASoC: rsrc-card: tidyup priv->snd_card setup timing 5) ASoC: rsrc-card: enable multi cpu/codec for DPCM 6) ASoC: rsrc-card: remove unused name 7) ASoC: rsnd-card: tidyup rsrc_priv_to_() 8) ASoC: rsrc-card: move rsrc_card_parse_daifmt() to upper side 9) ASoC: rsrc-card: tidyup return value of clock error 10) ASoC: rsrc-card: cleanup for DPCM 11) ASoC: rsnd: count each mod (SSI/SRC/DVC) 12) ASoC: rsnd: rsnd_mod has rsnd_priv 13) ASoC: rsnd: adds struct rsnd_dai_stream as on each fuction as parameter 14) ASoC: rsnd: add common interrupt handler for SSI/SRC/DMA 15) ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_get_adinr() 16) ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_dma_xxx() 17) ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_ssi_xxx() 18) ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_src_xxx() 19) ASoC: rsnd: don't use rsnd_mod_to_io() on snd_kcontrol 20) ASoC: rsnd: move rsnd_mod_is_working() to rsnd_io_is_working() 21) ASoC: rsnd: remove io from rsnd_mod sound/soc/sh/rcar/core.c | 111 ++++++++++++++++++++++++--------- sound/soc/sh/rcar/dma.c | 113 ++++++++++++++++++++-------------- sound/soc/sh/rcar/dvc.c | 30 +++++---- sound/soc/sh/rcar/rsnd.h | 112 +++++++++++++++++++++------------ sound/soc/sh/rcar/rsrc-card.c | 438 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++------------------------------------------------------------------------- sound/soc/sh/rcar/src.c | 121 ++++++++++++++++++++---------------- sound/soc/sh/rcar/ssi.c | 96 +++++++++++++++++------------ 7 files changed, 558 insertions(+), 463 deletions(-) Best regards --- Kuninori Morimoto
