2014-03-05ASoC: rsnd: add probe/remove callback on rsnd_mod_opsKuninori Morimoto1-0/+6
Each rsnd mod needs specific probe method, and its best timing is DAI probe timing. But current code runs it mod probe timing. This patch adds new probe/remove callback to solve it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-05ASoC: rsnd: call rsnd_scu_ssi_mode_init() from SSIKuninori Morimoto1-0/+3
Current R-Car sound driver is assuming that SCU mod is used even though it is not needed. Because scu.c is controlling SSIU too. (it is Gen1 compatibility) But, SCU mod will be really not used if new platform dai feature was added. Thus, rsnd_scu_ssi_mode_init() is called from SSI directory by this patch.

2014-03-05ASoC: rsnd: Get correct SCU IDKuninori Morimoto1-0/+14
Current rsnd driver is assuming that SCU/SRU ID is same as SSIU/SSI ID, because Gen1 can't select it. But, Gen2 can select it. The SCU/SRU/SSIU/SSI pair depends on the platform. This patch get correct SCU ID from platform info. To keep compatible, it still assuming SCU ID = SSI ID if platform doesn't have info Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-04ASoC: rsnd: share reg_field and reduce memoryKuninori Morimoto1-28/+53

2014-03-04ASoC: rsnd: use mod array instead of list on rdaiKuninori Morimoto1-4/+8
struct rsnd_dai_stream used list for mod list. It added only odd flexibility to current driver, and it is a factor which makes extendibility difficult. rsnd use mod array instead of list from now.

2014-03-04ASoC: rsnd: run rsnd_path_init() when probe() timingKuninori Morimoto1-9/+0
Current rsnd SSIU/SSI/SCU/SRU path is set when playback/capture starts up. But it is meaningless method, since the path is based on platform and can be set in probe() timing. This patch sets the path on probe() timing. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-02-03ASoC: rsnd: add Gen2 SRC and DMAEngine supportKuninori Morimoto1-0/+25
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 Morimoto1-5/+5
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 Morimoto1-1/+1
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>

2014-02-03ASoC: rsnd: merge SRC clock timing/settingKuninori Morimoto1-4/+4
SRC clock and timing setting register exist in SRU and ADG on Gen1. But, these are merged into ADG on Gen2. Current driver is supporting Gen1 SRC only at this point, but, above settings are set as different function. This patch merges these as preparation of Gen2 support.

SRU (Gen1) / SCU (Gen2) / SSIU (Gen2) are controlled under scu.c. (SCU + SSIU (Gen2) was SRU (Gen1)) And register of SSI_MODE0/1 are mapped on these IP. But these have been implemented under ssi.c on this driver. The naming is very confusable, but it should be implemented under scu.c Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-03ASoC: rsnd: rsnd_dai_is_clk_master() can be sharedKuninori Morimoto1-0/+1

2013-12-31ASoC: rsnd: add SRC (Sampling Rate Converter) supportKuninori Morimoto1-0/+18
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. This patch was tested via ak4554 codec, and supports Gen1 only at this point. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-12-31ASoC: rsnd: INT_ENABLE is needed only Gen2Kuninori Morimoto1-1/+1
INT_ENABLE is needed only Gen2. rsnd_mod_write() do nothing on Gen1, but it is confusable. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-12-31ASoC: rsnd: route setting is needed only Gen1Kuninori Morimoto1-5/+5
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. rsnd_scu_set_route() is needed only Gen1. This patch renames it to rsnd_scu_set_route_if_gen1() and it adds comment to rsnd_reg member in order to clarify it is used for Gen1.

2013-10-20ASoC: rcar: add rsnd_scu_hpbif_is_enable()Kuninori Morimoto1-0/+1
Current SSI needs RSND_SSI_DEPENDENT flag to decide dependent/independent mode. And SCU needs RSND_SCU_USE_HPBIF flag to decide HPBIF is enable/disable. But these 2 means same things.

2013-08-06ASoC: rsnd: SSI supports DMA transfer via BUSIFKuninori Morimoto1-0/+9
This patch adds BUSIF support for R-Car sound DMAEngine transfer. The sound data will be transferred via FIFO which can cover blank time which will happen when DMA channel is switching.

2013-08-06ASoC: rsnd: add common DMAEngine methodKuninori Morimoto1-0/+32
R-Car Sound driver will support DMA transfer in the future, then, SSI/SRU/SRC will use it. Current R-Car can't use soc-dmaengine-pcm.c since its DMAEngine doesn't support dmaengine_prep_dma_cyclic(), and SSI needs double plane transfer (which needs special submit) on DMAC.

2013-08-06ASoC: rsnd: remove platform dai and add dai_id on platform settingKuninori Morimoto1-0/+3
Current rsnd driver is using struct rsnd_dai_platform_info so that indicate sound DAI information (playback/capture SSI ID). But, SSI settings were also required separately. Thus, platform settings was very un-understandable. This patch adds dai_id to SSI settings, and removed rsnd_dai_platform_info.
