2019-12-10ASoC: soc-core: remove snd_soc_disconnect_sync()Kuninori Morimoto
Sound card disconnecting operation was needed when "sound driver" was unbinded without unbinding "sound card". In such case, sound driver should be stopped even though it was playbacking/capturing. Otherwise clock open/close counter mismatch happen. One headache was that we can't skip unbind in error case because unbind operation doesn't check return value from each drivers. snd_soc_disconnect_sync() was added for these purpose, and Renesas sound card only is used it. But now, ALSA SoC automatically disconnect sound card when sound driver was unbinded. Thus, snd_soc_disconnect_sync() is no longer needed. This patch removes it.

There is no need to store the inverted DALIGN values in the table, as they can easily be calculated at run-time. This also protects against the introduction of inconsistencies between normal and inverted values by a future table modification. Reorder the two subexpressions in the AND check, to perform the least expensive check first.

2019-10-18ASoC: rsnd: Reinitialize bit clock inversion flag for every format settingJunya Monden
Unlike other format-related DAI parameters, rdai->bit_clk_inv flag is not properly re-initialized when setting format for new stream processing. The inversion, if requested, is then applied not to default, but to a previous value, which leads to SCKP bit in SSICR register being set incorrectly. Fix this by re-setting the flag to its initial value, determined by format.

Renesas sound device has many IPs and many situations. If platform/board uses MIXer, situation will be more complex. To avoid duplicate DVC kctrl registration when MIXer was used, it had original flags. But it was issue when sound card was re-binded, because no one can't cleanup this flags then. To solve this issue, commit 9c698e8481a15237a ("ASoC: rsnd: tidyup registering method for rsnd_kctrl_new()") checks registered card->controls, because if card was re-binded, these were cleanuped automatically. This patch could solve re-binding issue. But, it start to avoid MIX kctrl. To solve these issues, we need below.

2018-11-28ASoC: rsnd: tidyup registering method for rsnd_kctrl_new()Kuninori Morimoto
Current rsnd dvc.c is using flags to avoid duplicating register for MIXer case. OTOH, commit e894efef9ac7 ("ASoC: core: add support to card rebind") allows to rebind sound card without rebinding all drivers. Because of above patch and dvc.c flags, it can't re-register kctrl if only sound card was rebinded, because dvc is keeping old flags. (Of course it will be no problem if rsnd driver also be rebinded, but it is not purpose of above patch). This patch checks current card registered kctrl when registering. In MIXer case, it can avoid duplicate register if card already has same kctrl. In rebind case, it can re-register kctrl because card registered kctl had been removed when unbinding.

Gen2 has BUSIF0-3, Gen3 has BUSIF0-7 on some SSIU. Current driver is assuming it is using BUSIF0 as default. Thus, SSI is attaching SSIU (with BUSIF0) by using rsnd_ssiu_attach(). But, TDM split mode also needs other BUSIF to use it. This patch adds missing SSIU BUSIFx support. BUSIF is handled by SSIU instead of SSI anymore. Thus, its settings no longer needed on SSI node on DT. This patch removes its settings from Document, but driver is still keeping compatibility. Thus, old DT style is still working. But, to avoid confusing, it doesn't indicate old compatibility things on Document. New SoC should have SSIU on DT from this patch. 1) old style DT is still supported (= no rcar_sound,ssiu node on DT) 2) If ssiu is not indicated on playback/capture, BUSIF0 will be used as default playback = <&ssi3>; /* ssiu30 will be selected */ 3) you can select own ssiu playback = <&ssi32 &ssi3>; /* ssiu32 will be selected */ Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2018-09-03ASoC: rsnd: fixup not to call clk_get/set under non-atomicJiada Wang
Clocking operations clk_get/set_rate, are non-atomic, they shouldn't be called in soc_pcm_trigger() which is atomic. Following issue was found due to execution of clk_get_rate() causes sleep in soc_pcm_trigger(), which shouldn't be blocked. We can reproduce this issue by following > enable CONFIG_DEBUG_ATOMIC_SLEEP=y > compile, and boot > mount -t debugfs none /sys/kernel/debug > while true; do cat /sys/kernel/debug/clk/clk_summary > /dev/null; done & > while true; do aplay xxx; done This patch adds support to .prepare callback, and moves non-atomic clocking operations to it. As .prepare is non-atomic, it is always called before trigger_start/trigger_stop.

2018-06-18ASoC: rsnd: add rsnd_daidrv_get()Kuninori Morimoto
rsnd priv has many parameters. On __rsnd_dai_probe() it uses rsnd_rdai_get() to get rdai pointer, but is using priv->daidrv directly to get daidrvhv, but it is confusable for reader. This patch adds rsnd_daidrv_get() to get daidrv from priv. Now reader can understand that rdai and daidrv are related.
