* ASoC: atmel_ssc_dai: make option to choose clockBo Shen2014-02-121-0/+1
| | | | | | | | | | 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.

* ARM: atmel-ssc: change phybase type to dma_addr_tBo Shen2013-07-151-1/+1
| | | | | | | | | as the phybase paramter only used for DMA operation, change it's type from resource_size_t to dma_addr_t Signed-off-by: Bo Shen <voice.shen@atmel.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>

* ARM: at91: atmel-ssc: add platform device id tableBo Shen2012-11-061-0/+5
| | | | | | | | | | | | Add platform device id to check whether the SSC controller support pdc or dam for data transfer If match "at91rm9200_ssc", which support pdc for data transfer If match "at91sam9g45_ssc", which support dma for data transfer Signed-off-by: Bo Shen <voice.shen@atmel.com> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: atmel-ssc: include linux/io.h for raw ioJoachim Eastwood2012-08-281-0/+1
| | | | | | | | | | | | | | | | Include linux/io.h for raw io operations in atmel-scc header. This fixes the following build error: CC [M] sound/soc/atmel/atmel_ssc_dai.o sound/soc/atmel/atmel_ssc_dai.c: In function 'atmel_ssc_interrupt': sound/soc/atmel/atmel_ssc_dai.c:171: error: implicit declaration of function '__raw_readl' sound/soc/atmel/atmel_ssc_dai.c: In function 'atmel_ssc_shutdown': sound/soc/atmel/atmel_ssc_dai.c:249: error: implicit declaration of function '__raw_writel' Signed-off-by: Joachim Eastwood <joachim.eastwood@jotron.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* Driver for the Atmel on-chip SSC on AT32AP and AT91Hans-Christian Egtvedt2007-10-171-0/+312
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 [akpm@linux-foundation.org: init spinlock at compile time] Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Acked-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Cc: David Brownell <david-b@pacbell.net> Cc: Andrew Victor <andrew@sanpeople.com> Cc: Patrice Vilchez <patrice.vilchez@rfo.atmel.com> Cc: Nicolas Ferre <nicolas.ferre@rfo.atmel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
