2012-01-27ALSA: Convert at73c213 to module_spi_driverAxel Lin1-11/+1
This patch converts at73c213 to use the module_spi_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-06-28ALSA: atmel - update author email for ABDAC, AC97C and AT73C213Hans-Christian Egtvedt1-1/+1
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>
2010-11-11ALSA: AT73C213: Rectify misleading comment.Peter Rosin1-1/+1
The Atmel SSC can divide by even numbers, not only powers of two. Signed-off-by: Peter Rosin <peda@axentia.se> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2010-06-08ALSA: sound/spi: patch for the unuseful variable removalWan ZongShun1-1/+0
The '*bitclk' of structure 'snd_at73c213' seems no use, so I make a patch to remove the unnecessary variable. Signed-off-by: Wan ZongShun <mcuos.com@gmail.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-01-12ALSA: Convert to snd_card_create() in other sound/*Takashi Iwai1-4/+3
Convert from snd_card_new() to the new snd_card_create() function in other sound subdirectories. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-05-27sound: Convert to menuconfigTakashi Iwai1-3/+10
Convert menu in sound Kconfig files to menuconfig and if. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-04-24[ALSA] at73c213: Add constraints for periods valueAtsushi Nemoto1-0/+6
The interrupt handler always provide runtime->period_size data, so it works correctly only if buffer_size was a multiple of period_size. This patch fixes periodic click noise. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-04-24[ALSA] at73c213: remove redundant private_free routineAtsushi Nemoto1-10/+0
snd_pcm_lib_preallocate_free_for_all() is called from snd_pcm_free() just after calling the private_free routine. So there should be no need to call it in driver's private_free routine.

2008-04-24[ALSA] at73c213: monaural supportAtsushi Nemoto1-4/+15
Add support for monaural playback to at73c213 driver. The sound will be apear on L-channel. Tested on AT91SAM9260-EK. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-04-24[ALSA] at73c213: fix error checking for clk APIAtsushi Nemoto1-1/+2
The clk_round_rate() and clk_set_rate() will return int, so not store thier return value to unsigned long variable. This bug hides real error on these API.

2008-04-24[ALSA] Add __devinit macro to at73c213 sound driver probe functionsHans-Christian Egtvedt1-3/+3
This patch adds __devinit to the functions used when probing. Will also reduce the memory footprint a bit if CONFIG_HOTPLUG is not enabled. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
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] at73c213: replace spinlock in mixer functions with a mutexHans-Christian Egtvedt1-15/+19
This patch fixes the locking bug in the at73c213 SPI sound driver. This bug was triggered because spinlocks were wrapped around the spi_sync call which might sleep. The fix was to add a mutex to the sound driver and replace the spinlocks in the mixer functions with mutex lock/unlock. Tested on STK1000/STK1002.

2007-10-16[ALSA] ALSA sound driver for the AT73C213 DAC using Atmel SSC driverHans-Christian Egtvedt4-0/+1276
This patch adds support for the AT73C213 DAC using the misc Atmel SSC driver in I2S mode. The driver also requires a SPI to setup the registers and control volume. It has been tested with an AT32AP7000 on the ATSTK1000 development board. The driver should also work with any Atmel device with an SSC module supported by the Atmel SSC driver (atmel-ssc). The atmel-ssc driver is just submitted to the Linux kernel.
