Firstly, fail probe if we can't register the regulator notifiers as this will cause the cache to never be synchronised which will result in odd behaviour if the regulators are controllable. Secondly, we don't need to call regulator_bulk_disable if the enable fails, because the regulator core will handle this clean up for us. Finally, we need to disable the regulators if snd_soc_register_codecs fails.

But, result of DMA ML discussion, it was concluded that it is not a general purpose DMAC. And it should be moved from current DMAEngine to rsnd driver. So, Audio DMAC peri peri become non DMAEngine. OTOH, ALSA SoC has soc-generic-dmaengine-pcm implementation. but it seems difficult to use this generic implementation on rsnd driver at this point, since it needs to fallback to PIO mode if DMA can't use. and additionally it needs 2 DMAC (= Audio DMAC / Audio DMAC peri peri). These are not "generic" feature. Of course I will try to use this generic dmaengine in the future somehow, but just use current style at this point until it can formally use 2 DMACs. This patch adds new dma.c and moves current dma code to dma.c from core.c.

And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine. But, in result of DMA ML discussion, 2nd DMAC was concluded that it is not a general purpose DMAC (2nd DMAC is for Device to Device inside sound system). Additionally, current DMAEngine can't support Device to Device, and we don't have correct DT bindings for it at this point. So the easiest solution for it is that move it from DMAEngine to rsnd driver. Audio DMAC peri peri is controlled from sound driver without DMAEngine by this patch.

And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine. But, in result of DMA ML discussion, 2nd DMAC was concluded that it is not a general purpose DMAC (2nd DMAC is for Device to Device inside sound system). Additionally, current DMAEngine can't support Device to Device, and we don't have correct DT bindings for it at this point. So the easiest solution for it is that move it from DMAEngine to rsnd driver. dma-names on DT was implemented as no difference between 1st / 2nd DMAC's, since rsnd had assumed that both DMACs are implemented as DMAEngine. That style was "src_dst". But now, 2nd DMAC was implemented as non DMAEngine, and it doesn't need dma-names anymore. So, this dma-names rule is no longer needed. And additionally, dma-names was assumed that it has all (= SSI/SSIU/SRC/DVC) nodes under sound node. In upstream code, no SoC/platform is supporting DMA for rsnd driver yet. This means there is no compatible issue if this patch changes dma-names's rule of DT. This patch assumes dma-names for 1st DMAC are tx/rx base, and listed in each SSI/SRC/DVC subnode ex) rcar_sound,dvc { dvc0: dvc@0 { dmas = <&audma0 0xbc>; dma-names = "tx"; }; ... rcar_sound,src { src0: src@0 { ... dmas = <&audma0 0x85>, <&audma1 0x9a>; dma-names = "rx", "tx"; }; ... rcar_sound,ssi { ssi0: ssi@0 { ... dmas = <&audma0 0x01>, <&audma1 0x02>, <&audma0 0x15>, <&audma1 0x16>; dma-names = "rx", "tx", "rxu", "txu"; }; ...

And it will be invoked before updating dapm widget power. In some machine driver, snd_soc_dai_set_sysclk is called in dapm event to switch codec sysclk to RC clock in idle mode. And in some use cases (such as syspend/resume) hw_params will not be called when the dapm widget is powered up. As a result, is_sys_clk_from_pll will return 0 although it is supposed to be 1. To solve this, we let is_sys_clk_from_pll check sysclk sysclk_src which is stored in private data and don't change the value of sysclk_src when codec sysclk is switched to internal clock. The internal clock can only be used in idle mode, so it sould be fine if we don't set sysclk_src to internal clock.

Also, we set codec idle_bias_off = true. As a result, codec driver will not suspend as we expect. On Braswell, we don't need the jack detection when suspend but need it after resume, so export the jack suspend/resume APIs which are provided for machine driver to control during suspend/resume.

But, sound card driver point of view, it is difficult to add this DPCM feature on simple-card driver. Especially, DT binding support is very difficult. This patch implements DPCM feature on DT as Renesas specific sound card. This new driver is copied from current simple-card driver. Main difference between simple-card and this driver are... 1. removed unused feature from simple-card 2. removed driver named prefix from DT property 3. CPU will be FE, CODEC will be BE with snd-soc-dummy 4. it supports sampling rate convert via .be_hw_params_fixup 5. board specific routing is implemented in driver Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown --- .../bindings/sound/renesas,rsrc-card.txt | 66 +++ sound/soc/sh/Kconfig | 5 + sound/soc/sh/rcar/Makefile | 5 +- sound/soc/sh/rcar/rsrc-card.c | 489 +++++++++++++++++++++ 4 files changed, 564 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/sound/renesas,rsrc-card.txt create mode 100644 sound/soc/sh/rcar/rsrc-card.c (limited to 'sound') diff --git a/Documentation/devicetree/bindings/sound/renesas,rsrc-card.txt b/Documentation/devicetree/bindings/sound/renesas,rsrc-card.txt new file mode 100644 index 000000000000..12e287ed4dce --- /dev/null +++ b/Documentation/devicetree/bindings/sound/renesas,rsrc-card.txt @@ -0,0 +1,66 @@ +Renesas Sampling Rate Convert Sound Card: + +Renesas Sampling Rate Convert Sound Card specifies audio DAI connections of SoC <-> codec. + +Required properties: + +- compatible : "renesas,rsrc-card," + Examples with soctypes are: + - "renesas,rsrc-card,lager" + - "renesas,rsrc-card,koelsch" +Optional properties: + +- card_name : User specified audio sound card name, one string + property. +- cpu : CPU sub-node +- codec : CODEC sub-node + +Optional subnode properties: + +- format : CPU/CODEC common audio format. + "i2s", "right_j", "left_j" , "dsp_a" + "dsp_b", "ac97", "pdm", "msb", "lsb" +- frame-master : Indicates dai-link frame master. + phandle to a cpu or codec subnode. +- bitclock-master : Indicates dai-link bit clock master. + phandle to a cpu or codec subnode. +- bitclock-inversion : bool property.

Since the charging can take a rather long time (up to multiple seconds) it is done asynchronously without blocking. A delayed work item is run once the charging is finished and the device is switched to the target bias level. This all done asynchronously to the regular DAPM sequence accessing the same data structures and registers without any looking, which can lead to race conditions. Furthermore this potentially delays the start of stream on the CODEC while the rest of the system is already up and running, meaning the first bytes of audio are lost. It also does no comply with the assumption of the DAPM core that if set_bias_level() returned successfully the device will be at the requested bias level. This patch slightly refactors things and makes sure that the caps charging is properly integrated into the DAPM sequence. When transitioning from SND_SOC_BIAS_OFF to SND_SOC_BIAS_STANDBY the part will be put into fast charging mode and a work item will be scheduled that puts it back into standby charging once the charging period has elapsed. If a playback or capture stream is started while charging is in progress the driver will now wait in SND_SOC_BIAS_PREPARE until the charging is done. This makes sure that charging is done asynchronously in the background when the chip is idle, but at the same time makes sure that playback/capture is not started before the charging is done.

Since the charging can take a rather long time (up to multiple seconds) it is done asynchronously without blocking. A delayed work item is run once the charging is finished and the device is switched to the target bias level. This all done asynchronously to the regular DAPM sequence accessing the same data structures and registers without any looking, which can lead to race conditions. Furthermore this potentially delays the start of stream on the CODEC while the rest of the system is already up and running, meaning the first bytes of audio are lost. It also does no comply with the assumption of the DAPM core that if set_bias_level() returned successfully the device will be at the requested bias level. This patch slightly refactors things and makes sure that the caps charging is properly integrated into the DAPM sequence. When transitioning from SND_SOC_BIAS_OFF to SND_SOC_BIAS_STANDBY the part will be put into fast charging mode and a work item will be scheduled that puts it back into standby charging once the charging period has elapsed. If a playback or capture stream is started while charging is in progress the driver will now wait in SND_SOC_BIAS_PREPARE until the charging is done. This makes sure that charging is done asynchronously in the background when the chip is idle, but at the same time makes sure that playback/capture is not started before the charging is done.

As part of this change the existing controls "TX Playback Switch" (controlled power for the SPDIF TX block) and "AIF Playback Switch" (controlled power for the AIF block) are both removed, as they are now redundant since the power state of those blocks is controlled automatically by DAPM. There are several benefits of this change, the most important of which is this change adds support for powering down the SPDIF RX block. The RX block will automatically assume control of the PLL on the chip when it is receiving a signal, so leaving this enabled all the time as was currently done in the driver can be problematic. An incoming SPDIF signal that is not being used can completely destroy the clocking for an in use TX signal. But this change ensures that the RX block will only be powered when the user intends to be receiving data, thus avoiding this issue. Additional benefits include the chip being simpler to operate as the power no longer needs to be manually controlled between use-cases and a small power saving (although it is acknowledged that this is likely unimportant in the typical use-cases for this chip).

This can be problematic when using output clocks from the wm8804 for other devices. The snd_soc_codec_set_pll API defines that a clock should be available once the call returns, however, with all the clocking controlled in set_bias_level this is not currently the case. This patch enables pm_runtime for the wm8804, enabling both the regulators and the oscillator when the chip resumes, and enabling the PLL in the snd_soc_codec_set_pll call. Naturally the enabling the PLL will also cause the chip to resume.

Unfortunately this is after the pll-out GPIO is configured which is selectable in the device tree. Therefore it is not possible to use GPIO4 for pll-out. Therefore this patch removes the configuration of GPIO4.
