[alsa-devel] [PATCH] ALSA: hda - Add CX20582 and OLPC XO-1.5 support
by Daniel Drake 16 Jul '09

16 Jul '09

This adds support for the Conexant CX20582 codec, based on code from http://www.linuxant.com/alsa-driver/alsa-driver-linuxant-1.0.19ppch12-1.noa… This is the codec to be shipped in the OLPC XO-1.5, so this patch also includes an XO-specific profile. Resultant configuration: http://dev.laptop.org/~dsd/20090713/codec0.txt http://dev.laptop.org/~dsd/20090713/codec0.svg As the Linuxant code is structured differently to the other codecs, I was unable to cleanly reimplement everything in the generic and Dell profiles as more info is needed (e.g. codec graphs). I simplified those profiles so that hopefully it will not break anyone's audio. If it does, it may be worth returning -ENODEV from patch_cx5066 on non-OLPC systems, and then fixing snd_hda_codec_configure() to fall back on the generic parser, at least until support for other systems is figured out. --- sound/pci/hda/patch_conexant.c | 479 ++++++++++++++++++++++++++++++++++++++++ 1 files changed, 479 insertions(+), 0 deletions(-) diff --git a/sound/pci/hda/patch_conexant.c b/sound/pci/hda/patch_conexant.c index 4fcbe21..77b4f28 100644 --- a/sound/pci/hda/patch_conexant.c +++ b/sound/pci/hda/patch_conexant.c @@ -108,6 +108,8 @@ struct conexant_spec { struct hda_input_mux private_imux; hda_nid_t private_dac_nids[AUTO_CFG_MAX_OUTS]; + unsigned int dell_automute; + unsigned int port_d_mode; }; static int conexant_playback_pcm_open(struct hda_pcm_stream *hinfo, @@ -1908,6 +1910,480 @@ static int patch_cxt5051(struct hda_codec *codec) return 0; } +/* Conexant 5066 specific */ + +static hda_nid_t cxt5066_dac_nids[1] = { 0x10 }; +static hda_nid_t cxt5066_adc_nids[3] = { 0x14, 0x15, 0x16 }; +static hda_nid_t cxt5066_capsrc_nids[1] = { 0x17 }; +#define CXT5066_SPDIF_OUT 0x21 + +static struct hda_channel_mode cxt5066_modes[1] = { + { 2, NULL }, +}; + +static void cxt5066_update_speaker(struct hda_codec *codec) +{ + struct conexant_spec *spec = codec->spec; + unsigned int pinctl; + + snd_printdd("CXT5066: update speaker, hp_present=%d\n", + spec->hp_present); + + /* Port A (HP) */ + pinctl = ((spec->hp_present & 1) && spec->cur_eapd) ?

If you just blindly initialise the variable as you are doing then the warning goes away but any problematic code remains so the situation is worse. In this case I suspect that whatever compiler you are using (none of those I've tried with seem to be doing this) isn't able to figure out that if we skip initialising the variable then we use exactly the same condition to return from the function before we try to use the variable. For something like this the warning can normally be worked around by changing the control flow so that the compiler is able to figure out that things are safe.

At best, you can try again GPIO pins and reverting COEF setup by my earlier patch, and try some more adjustments of widgets amp or pinctl via hda-verb or hda-analyzer... Takashi

[alsa-devel] New Audio Driver Design
by jassi brar 15 Jul '09

15 Jul '09

Hello, I am to write an ALSA driver for my SOC which has a dedicated DSP subsystem which can be loaded with decoder instructions and parameteres, and then we load it with encoded data. The dsp then decodes the data and sends it to the PCM controller. Could someone please refer me to some similar driver/codec which already does that? If not, how should i design the driver? :- Should I load the encoder inst/params using firmware API? Then, which API should I use to submit encoded data to the DSP? Any pointers please? Thanks.

[alsa-devel] [PATCH 3/3] ASoC: MAX9877: add MAX9877 amp driver
by Joonyoung Shim 15 Jul '09

15 Jul '09

The MAX9877 combines a high-efficiency Class D audio power amplifier with a stereo Class AB capacitor-less DirectDrive headphone amplifier. The max9877_add_controls() is called to register the MAX9877 specific controls on machine specific init() of the machine driver. The datasheet for the MAX9877 can find at the following url: http://datasheets.maxim-ic.com/en/ds/MAX9877.pdf Signed-off-by: Joonyoung Shim <jy0922.shim(a)samsung.com> --- This patch is version 2. I updated from review of version 1. Change log: v2: - add SND_SOC_MAX9877 to SND_SOC_ALL_CODECS on Kconfig. - use SOC_DOUBLE_R_EXT_TLV instead of SOC_SINGLE_EXT_TLV for HP volume control. - modify max9877_get_reg() and max9877_set_reg for double reg controls. - add EXPORT_SYMBOL_GPL(max9877_add_controls). sound/soc/codecs/Kconfig | 5 + sound/soc/codecs/Makefile | 6 + sound/soc/codecs/max9877.c | 270 ++++++++++++++++++++++++++++++++++++++++++++ sound/soc/codecs/max9877.h | 37 ++++++ 4 files changed, 318 insertions(+), 0 deletions(-) create mode 100644 sound/soc/codecs/max9877.c create mode 100644 sound/soc/codecs/max9877.h diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index b674d3a..16a710f 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -49,6 +49,7 @@ config SND_SOC_ALL_CODECS select SND_SOC_WM9705 if SND_SOC_AC97_BUS select SND_SOC_WM9712 if SND_SOC_AC97_BUS select SND_SOC_WM9713 if SND_SOC_AC97_BUS + select SND_SOC_MAX9877 if I2C help Normally ASoC codec drivers are only built if a machine driver which uses them is also built since they are only usable with a machine @@ -188,3 +189,7 @@ config SND_SOC_WM9712 config SND_SOC_WM9713 tristate + +# Amp +config SND_SOC_MAX9877 + tristate diff --git a/sound/soc/codecs/Makefile b/sound/soc/codecs/Makefile index 301eb08..cf111c9 100644 --- a/sound/soc/codecs/Makefile +++ b/sound/soc/codecs/Makefile @@ -38,6 +38,9 @@ snd-soc-wm9705-objs := wm9705.o snd-soc-wm9712-objs := wm9712.o snd-soc-wm9713-objs := wm9713.o +# Amp +snd-soc-max9877-objs := max9877.o + obj-$(CONFIG_SND_SOC_AC97_CODEC) += snd-soc-ac97.o obj-$(CONFIG_SND_SOC_AD1980) += snd-soc-ad1980.o obj-$(CONFIG_SND_SOC_AD73311) += snd-soc-ad73311.o @@ -77,3 +80,6 @@ obj-$(CONFIG_SND_SOC_WM9081) += snd-soc-wm9081.o obj-$(CONFIG_SND_SOC_WM9705) += snd-soc-wm9705.o obj-$(CONFIG_SND_SOC_WM9712) += snd-soc-wm9712.o obj-$(CONFIG_SND_SOC_WM9713) += snd-soc-wm9713.o + +# Amp +obj-$(CONFIG_SND_SOC_MAX9877) += snd-soc-max9877.o diff --git a/sound/soc/codecs/max9877.c b/sound/soc/codecs/max9877.c new file mode 100644 index 0000000..7df9a7c --- /dev/null +++ b/sound/soc/codecs/max9877.c @@ -0,0 +1,270 @@ +/* + * max9877.c -- amp driver for max9877 + * + * Copyright (C) 2009 Samsung Electronics Co.Ltd + * Author: Joonyoung Shim <jy0922.shim(a)samsung.com> + * + * This program is free software;

[alsa-devel] [PATCH 2/3] ASoC: add SOC_DOUBLE_R_EXT_TLV control type
by Joonyoung Shim 15 Jul '09

This is a macro for double controls with special callback function and TLV. The SOC_DOUBLE_R_EXT_TLV needs two registers and one shift for double controls.
