2014-12-03ASoC: rsnd: tidyup SSI interrupt enable/disable methodKuninori Morimoto1-3/+22
Current SSI doesn't care interrupt "disable" method. And, it is used when PIO mode only at this point. SSI interrupt will be used for sound R/L issue workaround when DMA mode too. This patch tidyup SSI interrupt enable/disable method. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-03ASoC: rsnd: rsnd_src_ssiu_stop() stops SSIU compulsorilyKuninori Morimoto1-4/+2
rsnd_src_ssiu_stop() is used to stop SSIU, but it shouldn't depend on whether it is using SSIU. This patch stops SSIU compulsorily. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-11-10ASoC: rsnd: tidyup debug message format and timingKuninori Morimoto1-4/+7
Current Renesas R-Car sound driver debug message is using random format (ex "ssi0: xxx" / "SSI0 xxx" / "ssi[0]: xxx") and confusable timing ("xxx probe failed" and "xxx probed" are shown in same time) This patch fixes these Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-07-31ASoC: rsnd: care audio local bus data format consistencyKuninori Morimoto1-0/+19
R-Car sound uses Audio Local Bus which uses Lch/Rch format. This bus is used if driver uses BUSIF. But sound data is written as Rch/Lch format in register. This means Rch <-> Lch will be inverted. SSIU :: BUSIF_DALIGN is used to controlling data format.

2014-07-31ASoC: rsnd: care detail of SRC_BSDSRKuninori Morimoto1-1/+31
Driver should care more detail of SRC_BSDSR settings. The sound includes noise without this patch if it used SRC. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-06-28ASoC: rsnd: SSI + DMA can select BUSIFKuninori Morimoto1-10/+27
Sound data needs to be sent to R-Car sound SSI when playback. But, there are 2 interfaces for it. 1st is SSITDR/SSIRDR which are mapped on SSI. 2nd is SSIn_BUSIF which are mapped on SSIU. 2nd SSIn_BUSIF is used when DMA transfer, and it is always used if sound data came from via SRC. But, we can use it when SSI+DMA case too. (Current driver is assuming 1st SSITDR/SSIRDR for it) 2nd SSIn_BUSIF can be used as FIFO. This is very helpful/useful for SSI+DMA. But DMA address / DMA ID are not same between 1st/2nd cases. This patch care about these settings.

2014-05-26ASoC: rsnd: module name is unifiedKuninori Morimoto1-3/+20
Renesas sound driver uses many modules (= SSI/SRC/DVC), and each module had own name. But, each module name can be used as several purpose, like clock name, DMA name etc... This patch uses common name for each module. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-05-26ASoC: rsnd: remove rsnd_src_non_opsKuninori Morimoto1-10/+10
Renesas sound driver is supporting Gen1/Gen2. SRC probe can return error if it was unknown generation. Now, rsnd_src_non_ops is not needed. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-05-13ASoC: rsnd: add rsnd_get_adinr()Kuninori Morimoto1-23/+3
SRC module needs ADINR register settings, but, it has many similar xxx_ADINR register, and needs same settings. This patch adds rsnd_get_adinr() to sharing code. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-05-08ASoC: rsnd: remove compatibility codeKuninori Morimoto1-48/+21
Now, all platform is using new style rsnd_dai_platform_info. Keeping compatibility is no longer needed. We can cleanup code. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-04-11ASoC: rsnd: fix clock prepare/unprepareBen Dooks1-2/+2
As with the previous commit, before a clock can be used it must be prepared for use. Change from clk_enable() and clk_disable() to the versions of the calls which also prepare and un-prepare the clocks. Will fix warnings from the clock code when this is used.

2014-03-05ASoC: rsnd: rename scu to srcKuninori Morimoto1-0/+687
R-Car sound has SCU unit which has SRC/CTU/MIX/DVC, and current rsnd driver has scu.c and scu module. Current scu.c has SRC support only. My first concept was control these feature on scu.c but, it become difficult and un-understandable now.
