commit c0ea089d ("ASoC: rsnd: rsnd_mod_name() handles both name and ID") merged "name" and "ID" on rsnd_mod_name() to handle sub-ID (= for CTU/BUSIF). Then, it decided to share static char to avoid pointless memory. But, it doesn't work correctry in below case, because last called name will be used. dev_xxx(dev, "%s is connected to %s\n", rsnd_mod_name(mod_a), /* ssiu[00] */ rsnd_mod_name(mod_b)); /* ssi[0] */ -> rcar_sound ec500000.sound: ssi[0] is connected to ssi[0] ~~~~~~ ~~~~~~ We still don't want to have pointless memory, so let's use ring buffer. 16byte x 5 is very enough for this purpose. dev_xxx(dev, "%s is connected to %s\n", rsnd_mod_name(mod_a), /* ssiu[00] */ rsnd_mod_name(mod_b)); /* ssi[0] */ -> rcar_sound ec500000.sound: ssiu[00] is connected to ssi[0] ~~~~~~~~ ~~~~~~ Signed-off-by:

This patch adds TDM Split mode support. rsnd driver is assuming audio-graph-scu-card is used for Sound Card. This is very simple sample DT settings to use it. sound_card: sound { compatible = "audio-graph-scu-card"; ... convert-channels = <8>; /* TDM Split */ dais = <&rsnd_port0 /* playback ch1/ch2 */ &rsnd_port1 /* playback ch3/ch4 */ &rsnd_port2 /* playback ch5/ch6 */ &rsnd_port3 /* playback ch7/ch8 */ >; }; audio-codec { ... port { codec_0: endpoint@1 { remote-endpoint = <&rsnd_ep0>; }; codec_1: endpoint@2 { remote-endpoint = <&rsnd_ep1>; }; codec_2: endpoint@3 { remote-endpoint = <&rsnd_ep2>; }; codec_3: endpoint@4 { remote-endpoint = <&rsnd_ep3>; }; }; }; &rcar_sound { ... ports { rsnd_port0: port@0 { rsnd_ep0: endpoint { remote-endpoint = <&codec_0>; ... playback = <&ssiu30 &ssi3>; }; }; rsnd_port1: port@1 { rsnd_ep1: endpoint { remote-endpoint = <&codec_1>; ... playback = <&ssiu31 &ssi3>; }; }; rsnd_port2: port@2 { rsnd_ep2: endpoint { remote-endpoint = <&codec_2>; ... playback = <&ssiu32 &ssi3>; }; }; rsnd_port3: port@3 { rsnd_ep3: endpoint { remote-endpoint = <&codec_3>; ... playback = <&ssiu33 &ssi3>; }; }; }; }; Signed-off-by:

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:

Current rsnd driver is using "%s[%d]" for mod name and ID, but, this ID portion might confusable. For example currently, CTU ID is 0 to 7, but using 00 to 13 (= 00, 01, 02, 03, 10, 11, 12, 13) is very best matching to datasheet. In the future, we will support BUSIFn, but it will be more complicated numbering. To avoid future confusable code, this patch modify rsnd_mod_name() to return understandable name. To avoid using pointless memory, it uses static char and snprintf, thus, rsnd_mod_name() user should use it immediately, and shouldn't keep its pointer. Signed-off-by:

ID for CTU and SSIU are confusable. 1 CTU has 4 sub nodes. This means, CTU0 has CTU01 - CTU03, CTU1 has CTU10 - CTU13. SSIU is more confusable. Gen2 SSIU has BUSIF0-3, Gen3 SSIU has BUSIF0-7, but not for all SSIU. In rsnd driver, each mod drivers are assuming rsnd_mod_id() returns main device ID (In CTU case CTU0-1, SSIU case SSIU0-9), not serial number. This patch adds new .id/.id_sub to handling more detail ID. Signed-off-by:

Current rsnd driver will fallback to PIO mode if it can't get DMA handler. But, DMA might return -EPROBE_DEFER when probe timing. This driver always fallback to PIO mode especially from commit ac6bbf0c ("iommu: Remove IOMMU_OF_DECLARE") because of this reason. The DMA driver will be probed later, but sound driver might be probed as PIO mode in such case. This patch fixup this issue. Then, -EPROBE_DEFER is not error. Thus, let's don't indicate error message in such case. And it needs to call rsnd_adg_remove() individually if probe failed, because it registers clk which should be unregister. Maybe PIO fallback feature itself is not needed, but let's keep it so far. Signed-off-by:

Main purpose of .nolock_start is we need to call some function without spinlock. OTOH we have .prepare which main purpose is called under atomic context. Then, it is called without spinlock. In summary, our main callback init/quit, and start/stop are called under "atomic context and with spinlock". And some function need to be called under "non-atomic context or without spinlock". Let's merge .nolock_start and prepare to be more clear code. Then, let's rename nolock_stop to cleanup Signed-off-by:

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.

The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

commit 4821d914 ("ASoC: rsnd: use dma_sync_single_for_xxx() for IOMMU") (= v1) which have been already reverted had supported IPMMU support on rsnd driver. Because memory allocating timing and DMAEngine access timing were different, it used continuous memory and called dma map function by itself. OTOH, it is using DMA descriptor mode (= DMA cyclic mode), thus, there was timing conflict between DMA sync/unsync and DMA transfer starting, and it maked sound noise. This patch supports IPMMU with coherent memory, and, it uses Audio DMAC dev for allocating memory by snd_pcm_lib_preallocate_pages_for_all() to indicate memory area to IPMMU. One note is that Playback/Capture need each paired Audio DMAC dev. Because of this, we need to keep each paired Audio DMAC dev when probing, and use it when allocating each memory for IPMMU.

rsnd driver is supporting Gen3. The difference between Gen1 and Gen2 were very big, but, between Gen2 and Gen3 are not so much. Thus, it is assuming Gen2 and Gen3 have compatible, therefore, there is no RSND_GEN3 and rsnd_is_gen3() macro. But in the future, it will need Gen2 and Gen3 different operation, and for Gen4. This patch adds missing RSND_GEN3 and rsnd_is_gen3() macro. Signed-off-by:

The suspend/resume callbacks are now optional, leading to a warning when they are unused: sound/soc/sh/rcar/core.c:1548:12: error: 'rsnd_resume' defined but not used [-Werror=unused-function] static int rsnd_resume(struct device *dev) ^~~~~~~~~~~ sound/soc/sh/rcar/core.c:1539:12: error: 'rsnd_suspend' defined but not used [-Werror=unused-function] static int rsnd_suspend(struct device *dev) This marks the as __maybe_unused to avoid the warning.

Use SET_SYSTEM_SLEEP_PM_OPS() macro instead of direct assignment to .suspend and .resume fields. This makes driver working after restore from hibernation. Signed-off-by:

Current rsnd driver is judging 16bit/24bit data by using runtime->sample_bits, but it is indicating physical size, not format size. This is confusable code. This patch uses snd_pcm_format_width() to be more correct code. Tested-by:

On Renesas sound device, DALIGN which exchanges channel position is needed because SW and HW are using defferent data order if 16bit data. It is not needed when 24bit data. rsnd_get_dalign() returns necessary value, but it was confusable code. This patch makes it more simple. Tested-by:

Renesas sound needs 8ch clock if TDM 6ch mode, and needs 2ch clock for 6ch or 8ch sound if Multi SSI mode. And these are related to before/after CTU (= Channel Transfer Unit). To calculate these we already has rsnd_runtime_channel_for_ssi() which returns runtime necessary channels. But, it based on runtime->channels which is not yet set when hw refine. We need to use hw_params instead of runtime->xxx when hw refine, and it is not needed after runtime was set. This patch adds new hw_params on rsnd_dai_stream, and it will be removed on rsnd_hw_params(). This is very temporary durty code, but it seems no choice at this point. Tested-by:

Renesas R-Car sound driver should be stopped if unbinded during playbacking/capturing. Otherwise clock open/close counter mismatch happen. One note is that we can't skip from remove function (= return -Exxx) in such case if user used unbind. Because unbind function doesn't check return value from each driver's remove function. This means we must to stop and remove driver in remove function. Now ASoC has snd_soc_disconnect_sync() for this purpose. Let's use it. Signed-off-by:

commit 4821d914 ("ASoC: rsnd: use dma_sync_single_for_xxx() for IOMMU") had supported IOMMU, but it breaks normal sound "recorde" and both PulseAudio's "playback/recorde". The sound will be noisy. That commit was using dma_sync_single_for_xxx(), and driver should make sure memory is protected during CPU or Device are using it. But if driver returns current "residue" data size correctly on pointer function, player/recorder will access to protected memory. IOMMU feature should be supported, but I don't know how to handle it without memory cache problem at this point. Thus, this patch simply revert it to avoid current noisy sound. Tested-by:

Current rsnd driver has rsnd_mod_id() which returns mod ID, and it returns -1 if mod was NULL. In the same time, this driver has rsnd_mod_name() which returns mod name, and it returns "unknown" if mod or mod->ops was NULL. Basically these "mod" never be NULL, but the reason why rsnd driver has such behavior is that DMA path finder is assuming memory as "mod == NULL". Thus, current DMA path debug code prints like below. Here "unknown[-1]" means it was memory. ... rcar_sound ec500000.sound: unknown[-1] from rcar_sound ec500000.sound: src[0] to rcar_sound ec500000.sound: ctu[2] rcar_sound ec500000.sound: mix[0] rcar_sound ec500000.sound: dvc[0] rcar_sound ec500000.sound: ssi[0] rcar_sound ec500000.sound: audmac[0] unknown[-1] -> src[0] ... 1st issue is that it is confusable for user. 2nd issue is rsnd driver has something like below code. mask |= 1 << rsnd_mod_id(mod); Because of this kind of code, some statically code checker will reports "Shifting by a negative value is undefined behaviour". But this "mod" never be NULL, thus negative shift never happen. To avoid these issues, this patch adds new dummy "mem" to indicate memory, and use it to indicate debug information, and, remove unneeded "NULL mod" behavior from rsnd_mod_id() and rsnd_mod_name(). The debug information will be like below by this patch ... rcar_sound ec500000.sound: mem[0] from rcar_sound ec500000.sound: src[0] to rcar_sound ec500000.sound: ctu[2] rcar_sound ec500000.sound: mix[0] rcar_sound ec500000.sound: dvc[0] rcar_sound ec500000.sound: ssi[0] rcar_sound ec500000.sound: audmac[0] mem[0] -> src[0] ...
