2014-02-12ASoC: rsnd: tidyup original for_each_rsnd_xxx macroKuninori Morimoto
Current for_each_rsnd_xxx macro will read out-of-array's memory after last loop operation. It was not good C language operation, and the binary which was compiled by (at least) gcc 4.8.1 is broken This patch tidyup these issues Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-07ASoC: rsnd: use device dependency clockKuninori Morimoto
Current R-Car sound driver is using device independent audio clock, but it is not good design for DT support. This patch adds device dependent clock support. But, there are some platform which is using independent audio clock. It is still supported at this point, but it will be removed soon.

2014-02-03ASoC: rsnd: add Gen2 SRC and DMAEngine supportKuninori Morimoto
Renesas sound Gen2 has SRC (= Sampling Rate Converter) which needs 2 DMAC. The data path image when you use SRC on Gen2 is [mem] -> Audio-DMAC -> SRC -> Audio-DMAC-peri-peri -> SSIU -> SSI This patch support SRC and DMAEnine. It is tested on R-Car H2 Lager board Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-02-03ASoC: rsnd: remove SSI dependent DMAEngine callbackKuninori Morimoto
Renesas Gen2 sound will use 2 DMAC which are Audio-DMAC, and Audio-DMAC-peri-peri. Current driver has callback function for each DMAC, because it assumed each DMAC needs special settings. But it became clear that these can share settings. This patch removes unnecessary callback Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-03ASoC: rsnd: extracts Gen1/Gen2 common partsKuninori Morimoto
Renesas sound IP Gen1/Gen2 are similar, but different. This patch extracts Gen1/Gen2 common and dependency parts, and create Gen1/Gen2 ops to control it. According to this structure, SSIU setup which has been implemented on ssi.c can be moved to scu.c (SRU/SSIU/SCU should be implemented on scu.c) Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-01-09ASoC: sh: Don't set unused struct snd_pcm_hardware fieldsLars-Peter Clausen
The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.

2013-12-31ASoC: rsnd: add SRC (Sampling Rate Converter) supportKuninori Morimoto
This patch adds SRC support to Renesas sound driver. SRC converts sampling rate between codec <-> cpu. It needs special codec chip, or very simple DA/AD converter to use it.

2013-12-31ASoC: rsnd: tidyup rsnd_ssi_master_clk_start() parameterKuninori Morimoto
Renesas sound has SRC (= Sampling Rate Converter), but, the HW implementation depends on its generation. It was part of SRU on Gen1, and SCU on Gen2. This SCU needs DMA transfer to use it. Current rsnd driver is using it as DMA transfer buffer (= no rate convert), and Gen1 is only supported at this point. This patch cleanup it with focusing about SRC and Gen2 part. ssi clock which is calculated from rsnd_ssi_master_clk_start() should have flexibility since Renesas sound has SRC (= Sampling Rate Converter). But current implementation is using runtime->rate directly.
