• dfaf53566   ASoC: atmel_ssc_dai: enable fslen extension feature ... Browse Code »

  When SSC work as master, it will generate the frame sync signal.
  On old SoCs, it only supports frame sync length less or equal to
  16bits, on newer SoCs, it supports frame sync length extension,
  which can support frame size larger than 16 bits.
  So, add this to make it supports playback 24/32 bits audio clips.

  When SSC works in slave mode, according to the hardware design, the
  clock can get from TK pin, also can get from RK pin. So, add one
  parameter to choose where the clock from.

• eb1f29306   Driver for the Atmel on-chip SSC on AT32AP and AT91 ... Browse Code »

  The Synchronous Serial Controller (SSC) on Atmel microprocessors are
  capable of tranceiving many frame based protocols, like I2S. Tested on the
  AT32AP7000/ATSTK1000.

  This driver is used in the ALSA sound driver for the AT73C213 external DAC
  on the ATSTK1000 development board for AVR32. This sound driver will be
  submitted soon.

  Hardware documentation can be found in the AT32AP7000 data sheet, which can
  be downloaded from
  http://www.atmel.com/dyn/products/datasheets.asp?family_id=682
