2008-09-24ALSA: oxygen: wait for ACK when resetting UARTClemens Ladisch1-0/+1
After sending a reset command to the UART, wait some time for the ACK to be generated (and to be read and dropped by the interrupt handler) before sending the next command. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2008-09-22ALSA: oxygen: add UART I/O functionsClemens Ladisch1-0/+21
Add functions to allow model drivers to communicate with external chips by doing I/O with the not-used-for-MIDI UART. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2008-05-19[ALSA] oxygen: save register writesClemens Ladisch1-4/+18
Save the written values of all CMI8788 and AC97 registers and of some of the DAC/ADC registers so that it is possible to restore the register state later. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-04-24[ALSA] oxygen: add I2C supportClemens Ladisch1-2/+21
Add a function to write I2C registers. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-01-31[ALSA] oxygen: use AC97 interruptClemens Ladisch1-8/+16
After an AC97 register read or write, use the AC97 interrupt instead of polling to wait for the access to be completed. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-01-31[ALSA] oxygen: reduce SPI clock frequency for AK4396/WM8785Clemens Ladisch1-1/+1
According to the datasheets, the SPI clock cycle must be at least 200 ns for the AK4396 and the WM8785, so we cannot use the default 160 ns. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-01-31[ALSA] oxygen: add register definitionsClemens Ladisch1-2/+2
Add more symbols for registers and register fields. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai1-1/+0
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2008-01-31[ALSA] add CMI8788 driverClemens Ladisch1-0/+194
Add the snd-oxygen driver for the C-Media CMI8788 (Oxygen) chip, used on the Asound A-8788, AuzenTech X-Meridian, Bgears b-Enspirer, Club3D Theatron DTS, HT-Omega Claro, Razer Barracuda AC-1, Sondigo Inferno, and TempoTec HIFIER sound cards.
