[ALSA] ALSA sound driver for the AT73C213 DAC using Atmel SSC driver
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. Please see mail thread Signed-off-by: Hans-Christian Egtvedt <> Signed-off-by: Takashi Iwai <> Signed-off-by: Jaroslav Kysela <>

+ Say Y here if you want to use the Atmel AT73C213 external DAC. This
+ DAC can be found on Atmel development boards.
+ This driver requires the Atmel SSC driver for sound sink, a
+ peripheral found on most AT91 and AVR32 microprocessors.
+ To compile this driver as a module, choose M here: the module will be
