2017-01-25ALSA: add Intel HDMI LPE audio driver for BYT/CHT-TJerome Anand
On Baytrail and Cherrytrail, HDaudio may be fused out or disabled by the BIOS. This driver enables an alternate path to the i915 display registers and DMA. Although there is no hardware path between i915 display and LPE/SST audio clusters, this HDMI capability is referred to in the documentation as "HDMI LPE Audio" so we keep the name for consistency. There is no hardware path or control dependencies with the LPE/SST DSP functionality. The hdmi-lpe-audio driver will be probed when the i915 driver creates a child platform device. Since this driver is neither SoC nor PCI, a new x86 folder is added Additional indirections in the code will be cleaned up in the next series to aid smoother DP integration Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Jerome Anand <jerome.anand@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-07-26sound: oss: Use kernel_read_file_from_path() for mod_firmware_load()Takashi Iwai
Since recently we have kernel_read_file_from_path(), and it's doing the same thing as our own home-baked mod_firmware_load(). Let's use the official API function and clean up the old code. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-03-23ALSA: hda - Make snd_hda_bus_type publicTakashi Iwai
Define the common hd-audio driver and device types to bind over snd_hda_bus_type publicly. This allows to implement other type of device and driver code over hd-audio bus. Now both struct hda_codec and struct hda_codec_driver inherit these new struct hdac_device and struct hdac_driver, respectively. The bus registration is done in subsys_initcall() to assure it before any other driver registrations. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-03-15ALSA: add LaCie FireWire Speakers/Griffin FireWave Surround driverClemens Ladisch
Add a driver for two playback-only FireWire devices based on the OXFW970 chip. v2: better AMDTP API abstraction; fix fw_unit leak; small fixes v3: cache the iPCR value v4: FireWave constraints; fix fw_device reference counting; fix PCR caching; small changes and fixes v5: volume/mute support; fix crashing due to pcm stop races v6: fix build; one-channel volume for LaCie v7: use signed values to make volume (range checks) work; fix function block IDs for volume/mute; always use channel 0 for LaCie volume Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Acked-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Tested-by: Jay Fenlason <fenlason@redhat.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2006-12-12[PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystemNicolas Pitre
Commit 2d4ba4a3b9aef95d328d74a17ae84f8d658059e2 introduced a dependency that was never meant to exist when the ac97_bus.c module was created. Move ac97_bus.c up the directory hierarchy to make sure it is built when selected even if sound is configured out so things work as originally intended.

2006-09-29[PATCH] build sound/sound_firmware.c only for OSSAdrian Bunk
All sound/sound_firmware.c contains is mod_firmware_load() that is a legacy API only used by some OSS drivers. This patch builds it into an own sound_firmware module that is only built depending on CONFIG_SOUND_PRIME making the kernel slightly smaller for ALSA users.

2006-06-28[ALSA] fix build failure due to snd-aoaTakashi Iwai

2006-06-22[ALSA] snd-aoa: add snd-aoaJohannes Berg
This large patch adds all of snd-aoa. Consisting of many modules, it currently replaces snd-powermac for all layout-id based machines and handles many more (for example new powerbooks and powermacs with digital output that previously couldn't be used at all). It also has support for all layout-IDs that Apple has (judging from their Info.plist file) but not all are tested. The driver currently has 2 known regressions over snd-powermac: * it doesn't handle powermac 7,2 and 7,3 * it doesn't have a DRC control on snapper-based machines I will fix those during the 2.6.18 development cycle.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
