2017-06-21ASoC: rsnd: fixup unsigned expression compared with zero: main_rateKuninori Morimoto3-6/+6
This patch fixes this WARNING sound/soc/sh/rcar/ssi.c:285:5-14: WARNING: Unsigned expression\ compared with zero: main_rate < 0 Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-06-15ASoC: rsnd: add rsnd_soc_hw_rule/constraint()Kuninori Morimoto2-2/+154
Current Renesas sound driver is assuming that all Sampling rate and channles are possible to use, but these are depends on inputed clock and SSI connection situation. For example, if it is using 1 SSI, enabled TDM mode and has 12288000 input clock, 2ch output can support until 192000Hz, but 6ch output can support until 64000Hz, 8ch can support 48000Hz. To control these situation correctly, it needs to support hw_constraints / refine feature. To support such feature, this patch adds new rsnd_soc_hw_rule/constraint() which adds hw rule of Channel and Sampling Rate.

2017-06-15ASoC: rsnd: add rsnd_adg_clk_query()Kuninori Morimoto2-26/+28
Current Renesas sound driver is assuming that all Sampling rate and channles are possible to use, but these are depends on inputed clock and SSI connection situation. For example, if it is using 1 SSI, enabled TDM mode and has 12288000 input clock, 2ch output can support until 192000Hz, but 6ch output can support until 64000Hz, 8ch can support 48000Hz. To control these situation correctly, it needs to support hw_constraints / refine feature. To support such feature, it needs SSI clock query feature, and it needs ADG clock query feature. Current ADG has rsnd_adg_ssi_clk_try_start() and it is doing similar things, but it try to setup ADG register in same time. This is not needed. This patch adds new rsnd_adg_clk_query() and separates query feature and register setting feature in adg.c Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-06-15ASoC: rsnd: rename "slots" related variableKuninori Morimoto4-37/+49
Current Renesas sound driver has slots and slots_num in struct rsnd_dai, but these are very un-understandable naming (It had named from TDM slots). In this driver, the "slots" means total usable channels, and "stot_num" means SSI lane number if Multi SSI was used. To more understandable code, this patch renames "slots" to "max_channels", and "slots_num" to "ssi_lane", and replaces related functions name.

2017-06-14ASoC: rsnd: reduce confusable macro parameter magicKuninori Morimoto1-2/+3
rsnd_dai_call() macro is using "priv" inside. Thus, if caller function doesn't have "priv" related operation, strange phenomenon occur which code is using "priv", but compiler indicates "unused variable 'priv'". >From code point of view, it is not problem, but it is very confusable. This patch removes "priv" from rsnd_dai_call() macro, and adds "priv" on caller function.

2017-06-13ASoC: rsnd: control kctrl items acceptance anytime/runtimeKuninori Morimoto5-6/+40
Current SRC/DVC/CTU adds kctrl for each device, and SRC can adjust its sampling rate during playback, thus, this feature should be enabled only *during* playback.

2017-06-13ASoC: rsnd: add detail explanation of L/R conversion timingKuninori Morimoto1-0/+18
Renesas Sound device *Hardware* L/R and Linux *Software* L/R are inverted. Because of this background, it needs to convert L/R. Then, DVC needs *Hardware* L/R, and Linux needs *Software* L/R. Because Playback/Capture needs different timing, and there is no explanation about it on source code / git log, this patch adds it.

2017-06-07ASoC: rsnd: cleanup pointer related codeKuninori Morimoto4-56/+65

2017-06-07ASoC: rsnd: update pointer more accurateKuninori Morimoto4-3/+48
Current rsnd driver updates pointer when DMA transfer was finished in DMA transfer mode. But PulseAudio requests more accurate pointer update when timer mode.

2017-05-29ASoC: add audio-graph-scu-card supportKuninori Morimoto3-0/+427
OF-graph base DT binding is used on V4L2, and ALSA SoC is using different style of DT today. Now ALSA SoC supports simple-card driver for generic/simple sound card, and we have simple-scu-card driver for simple-card + ALSA DPCM case. In the future, V4L2 / ALSA will support HDMI, and then, DT bindings between V4L2 / ALSA should be merged.
