2024-04-02ASoC: rsnd: cleanup regmap tableKuninori Morimoto
R-Car Sound is using almost same register mapping on each generation, therefore we can share it. Here indicates some memo/comments. SSI/SSIU/SCU have multi channels (SSI0 - SSI9 etc), but ADG is single, so, we don't need to have multi channel settings for it - rsnd_gen_regmap_init(..., 10, ..ADG, ...); + rsnd_gen_regmap_init(..., 1, ..ADG, ...); Gen4 added new SSI_BUSIF, but it is not used Gen4 calls rsnd_gen_regmap_init() for SDMC, but the address is calculated by rsnd_gen4_dma_addr(). It needs physical address, but other info are not needed. use NULL conf for it. - rsnd_gen_regmap_init(..., 10, ..SDMC, conf_sdmc); + rsnd_gen_regmap_init(..., 1, ..SDMC, conf_null); Gen4 have only SSI0/SSIU0, we don't need to have multi channel settings. - rsnd_gen_regmap_init(..., 10, ..SSI, ...); + rsnd_gen_regmap_init(..., 1, ..SSI, ...); SSI_MODE2 address is different between Gen2/3 and Gen4, but it is not used on Gen4. Thus we can share same regmap table.

2023-10-09ASoC: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

In general Renesas SoC's SSI/SRC are all enabled, but some SoC is not. H2 E2 SRC0 <= SRC1 SRC1 SRC2 SRC2 ... ... Renesas Sound driver is assuming that *all* modules are enabled, and thus it is using *data array* to access each modules. Because of it, we have been using "status = disabled" at DT, and using *full size* array but avoiding disabled module. ex) rcar_sound,src { src-0 { => status = "disabled"; }; src1: src-1 { ... }; ... But R-Car D3 have many disabled modules (It has SSI3/SSI4, SRC5/SRC6), and Renesas SoC maintainer don't want above style on DT. ex) rcar_sound,src { => src0: src-0 { status = "disabled"; }; => src1: src-1 { status = "disabled"; }; => src2: src-2 { status = "disabled"; }; => src3: src-3 { status = "disabled"; }; => src4: src-4 { status = "disabled"; }; src5: src-5 { ... }; src6: src-6 { ... }; }; rcar_sound,ssi { => ssi0: ssi-0 { status = "disabled"; }; => ssi1: ssi-1 { status = "disabled"; }; => ssi2: ssi-2 { status = "disabled"; }; ssi3: ssi-3 { ... }; ssi4: ssi-4 { ... }; }; To adjust it, it needs to care about related for_each_child_of_node() loop on rsnd driver, and it is used from... > grep -l for_each_child_of_node sound/soc/sh/rcar/* sound/soc/sh/rcar/core.c sound/soc/sh/rcar/ctu.c sound/soc/sh/rcar/dma.c sound/soc/sh/rcar/dvc.c sound/soc/sh/rcar/mix.c sound/soc/sh/rcar/src.c sound/soc/sh/rcar/ssi.c sound/soc/sh/rcar/ssiu.c This patch adjust to this situation.

2021-05-27ASoC: rsnd: protect mod->statusKuninori Morimoto
Renesas Sound uses many modules (SSI/SSIU/SRC/CTU/MIX/DVC/DMA), and supports complex connections/path. Thus each modules needs to save its status to correctly control it. This status is updated when by .trigger, and .hw_params/.hw_free. Renesas Sound is protecting modules by using lock when .trigger, but it was not enough to protecting each modules "status" if it was used from many paths. 1) .hw_params/.hw_free update status 2) another doesn't update status, but overwrites by same value This patch do 1) protects .hw_params/.hw_free by lock 2) do nothing if no status update Without this patch, protected mod->status (= .trigger) might be overwrote by non protected mod->status (= .hw_params / .hw_free), and in such case, CTU/MIX/DVC/SSIU/SSI which are used from many paths might get damage. If above issue happens, Renesas Sound will be hung (= silence) and never be recoverd. I could reproduce this issue by continue playing very short sound with loop very long term (3-4 hours) through 2 inputs (= MIXer). For updating rsnd_status_update(), this patch removes rsnd_dai_call() debug message. Because we already have debugfs support, and is not good match to new code. Reported-by: Linh Phung T.

2018-12-12ASoC: rsnd: remove RSND_REG_ from rsnd_regKuninori Morimoto
Current rsnd is using RSND_REG_xxx for register naming, and using RSND_REG_##f style macro for read/write. The biggest reason why it uses this style is that we can avoid non-existing register access. But, its demerit is sequential register access code will be very ugly. Current rsnd driver is well tested, so, let's remove RSND_REG_ from rsnd_reg, and cleanup sequential register access code.

2018-12-04ASoC: rsnd: fixup mod ID for CTU regmap read/writeKuninori Morimoto
commit c16015f36cc12824 ("ASoC: rsnd: add .get_id/.get_id_sub") add new .get_id/.get_id_sub to indicate module ID/subID. It is used for SSIU and CTU. In SSIU case, subID indicates BUSIF, but register settings is based on SSIU ID. OTOH, in CTU case, subID indicates CTU channel, and register settings is based on it. This means regmap read/write function needs to care it. This patch fixup this issue. It can't play MIXed sound without this patch.

2018-11-06ASoC: rsnd: add SSIU BUSIF supportKuninori Morimoto
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>

2018-11-05ASoC: rsnd: rsnd_mod_name() handles both name and IDKuninori Morimoto
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.

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.

Prepare <-> Cleanup functions pair has balanced calls. But in case of suspend mode no call to rsnd_soc_dai_shutdown() function, so cleanup isn't called. OTOH during resume mode function rsnd_soc_dai_prepare() is called, but calling rsnd_ssi_prepare() is skipped (rsnd_status_update() returns zero, bacause was not cleanup before). We need to call rsnd_ssi_prepare(), because it enables SSI clocks by calling rsnd_ssi_master_clk_start(). This patch allows to call prepare/cleanup functions always.

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".

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.
