| | | | | | | | | | | | | | | | This patch updates the email address of the sound drivers supported by me to an email account I will use on a more regular basis in the future. Signed-off-by: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* | treewide: Convert uses of struct resource to resource_size(ptr)Joe Perches2011-06-10
|/ | | | | | | | | | | | | | | | | | | | Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing. Mostly uncompiled, no cross-compilers.

* ALSA: fix invalid hardware.h include in ac97c for AVR32 architectureHans-Christian Egtvedt2011-01-25
| | | | | | | | | | This patch fixes the non-compiling AC97C driver for AVR32 architecture by include mach/hardware.h only for AT91 architecture. The AVR32 architecture does not supply the hardware.h include file.

* ALSA: AC97: add full duplex support for atmel AT91 and AVR.Sedji Gaouaou2010-03-25
| | | | | | | | | | | This patch add full duplex support on AT91 and AVR. It was a bug: we needed to check first if there are some chips opened so we could enable both reception and sending of the data.

* ALSA: AC97: add AC97 support for AT91.Sedji Gaouaou2010-03-25
| | | | | | | | | | | This patch add AC97 support for ATMEL AT91, using the AVR32 code. While AVR is using a DMA, the AT91 chips are using a Peripheral Data Controller.

* ALSA: snd-atmel-ac97c: cleanup registers when removing driverHans-Christian Egtvedt2009-04-05
| | | | | | | | This patch will set the channel A and control channel mode register to zero before disabling the AC97C peripheral. Signed-off-by: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: snd-atmel-ac97c: do a proper reset of the external codecHans-Christian Egtvedt2009-04-05
| | | | | | | | | This patch will enable the AC97C before resetting the external codec, leaving the AC97C disabled will result in floating I/O lines that can affect the reset procedure.

* ALSA: snd-atmel-ac97c: enable interrupts to catch events for error reportingHans-Christian Egtvedt2009-04-05
| | | | | | | | | | | | This patch will enable interrupts from AC97C and report about error conditions that occurs. On channel A both overrun and underrun will be enabled depending if playback and/or capture are enabled. On the control channel the overrun interrupt is enabled.

* ALSA: snd-atmel-ac97c: set correct size for buffer hardware parameterHans-Christian Egtvedt2009-04-05
| | | | | | | | | | | | This patch will set a proper maximum bytes for the buffer, which is: channels * bytes per sample * maximum periods * maximum bytes per period. It also sets the minimum periods to 6, a value chosen from testing, with a minimum of 6 periods the system has good time to fill in new audio data without skipping.

* ALSA: snd-atmel-ac97c: do not overwrite OCA and ICA when assigning channelsHans-Christian Egtvedt2009-04-05
| | | | | | | | | | This patch will take care not to overwrite OCA and ICA registers when assigning input and output channels. It will also make sure the registers are at a known state when enabling a channel and clean up properly in case of an error.
