Lars-Peter Clausen	d32e03f0b6	ASoC: xtfpga-i2s: Add missing __rcu annotation ... tx_substeam is accessed using the RCU API and hence should have the __rcu annotation. Fixes the following sparse warnings: sound/soc/xtensa/xtfpga-i2s.c:165:24: error: incompatible types in comparison expression (different address spaces) sound/soc/xtensa/xtfpga-i2s.c:165:24: error: 'struct snd_pcm_substream [noderef] <asn:4>*' versus sound/soc/xtensa/xtfpga-i2s.c:165:24: error: 'struct snd_pcm_substream *' sound/soc/xtensa/xtfpga-i2s.c:255:24: error: incompatible types in comparison expression (different address spaces) sound/soc/xtensa/xtfpga-i2s.c:255:24: error: 'struct snd_pcm_substream [noderef] <asn:4>*' versus sound/soc/xtensa/xtfpga-i2s.c:255:24: error: 'struct snd_pcm_substream *' Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>	2015-07-29 15:07:54 +01:00
Vaishali Thakkar	36e914cc4b	ASoC: xtensa: Remove unnecessary snd_pcm_lib_preallocate_free_for_all() ... The ALSA core takes care that all preallocated memory is freed when the PCM itself is freed. There is no need to do this manually in the driver. Signed-off-by: Vaishali Thakkar <vthakkar1994@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>	2015-07-23 17:40:37 +01:00
Max Filippov	57b7068de5	ASoC: add xtensa xtfpga I2S interface and platform ... XTFPGA boards provides an audio subsystem that consists of TI CDCE706 clock synthesizer, I2S transmitter and TLV320AIC23 audio codec. I2S transmitter has MMIO-based interface that resembles that of the OpenCores I2S transmitter. I2S transmitter is always a master on I2S bus. There's no specialized audio DMA, sample data are transferred to I2S transmitter FIFO by CPU through memory-mapped queue interface.
