* sound: oxygen: handle cards with broken EEPROMClemens Ladisch2009-02-191-1/+10
| | | | | | | | | | | | | | | | | Under as yet unknown circumstances, the first word of the sound card's EEPROM gets overwritten. When this has happened, we cannot rely on the subsystem IDs that the kernel reads from the PCI configuration registers. Instead, we read the IDs directly from the EEPROM and do the ID matching manually. Because the model-specific driver cannot determine the model before calling oxygen_pci_probe(), that function now gets a get_model() callback as parameter. The customizing of the model structure, which was formerly done by the probe() callback, also has moved into get_model().

* sound: oxygen: make the owner module a parameter of the probe functionClemens Ladisch2009-02-191-2/+1
| | | | | | | | | | | Move the owner field out of the oxygen_model structure and make it a parameter of oxygen_pci_probe(), because the actual owner module does not depend on the card model. Furthermore, moving it out of the model structure allows us to create the card structure before the actual model is known.

* ALSA: oxygen: add self-documenting functionsClemens Ladisch2008-09-221-1/+6
| | | | | | | Introduce some trivial functions to better document the relationships of the various model callbacks. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* ALSA: oxygen: rename pcm_dev_cfgClemens Ladisch2008-09-221-3/+3
| | | | | | | Rename the pcm_dev_cfg field to device_config because there will be additional flags that do not describe PCM devices. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* ALSA: oxygen: add probe callbackClemens Ladisch2008-09-221-1/+1
| | | | | | | Add a probe callback to the model structure so that model-specific drivers can refine their model detection before the card is initialized. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* ALSA: oxygen: fix distorted output on AK4396-based cardsClemens Ladisch2008-08-291-0/+4
| | | | | | | | | | | | | | | When changing the sample rate, the CMI8788's master clock output becomes unstable for a short time. The AK4396 needs the master clock to do SPI writes, so writing to an AK4396 control register directly after a sample rate change will garble the value. In our case, this leads to the DACs being misconfigured to I2S sample format, which results in a wrong output level and horrible distortions on samples louder than -6 dB. To fix this, we need to wait until the new master clock signal has become stable before doing SPI writes.

* [ALSA] oxygen: separate out hardware initialization codeClemens Ladisch2008-05-191-2/+9
| | | | | | | | | Create separate functions for the code that initializes the hardware, as opposed to initializing internal driver state, so that they can be reused for resume support. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
* [ALSA] oxygen: simplify DAC volume initializationClemens Ladisch2008-05-191-8/+7
| | | | | | | | When initializing the DAC volume registers, we can just use the generic volume update functions instead of setting the registers manually. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>

* [ALSA] oxygen: generalize DAC volume TLV handlingClemens Ladisch2008-04-241-5/+2
| | | | | | | | Add a pointer for DAC volume TLV data to the model structure so that the model driver do not need to manually assign it in their control filter. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* [ALSA] oxygen: generalize handling of DAC volume limitsClemens Ladisch2008-04-241-0/+2
| | | | | | | | Add fields for the DAC volume limits to the module structure so that model drivers do not need to install their own control info handlers. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | The empty hifier_mixer_init() function is useless; remove it. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] oxygen: use SPDIF input only if presentClemens Ladisch2008-04-241-5/+0
| | | | | | | | If the card model does not have a digital input or an AC97 codec, disable the respective interrupt and mixer controls. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] oxygen: move MIDI flag to model structClemens Ladisch2008-04-241-1/+1
| | | | | | | | Put the flag that enables the MIDI port into the model structure instead of passing it as a separate parameter to oxygen_pci_probe(). Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] oxygen: make SPI/2-wire configuration model-specificClemens Ladisch2008-04-241-1/+1

* [ALSA] oxygen: change model-specific PCM device configurationClemens Ladisch2008-04-241-3/+3
| | | | | | | | | | When specifying which PCM devices to use, model drivers now use flags that also specify the routing between PCM devices and DMA channels instead of just DMA channel bits. This simplifies some code that checks for these flags. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* [ALSA] oxygen: revert SPI clock frequency change for AK4396/WM8785Clemens Ladisch2008-01-311-1/+1
| | | | | | | | | While the AK4396 and WM8785 datasheets say that the SPI clock cycle length must be at least 200 ns, 320 ns seems not to work reliably with the controller, so we better use 160 ns. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
