* ASoC: AMD: Audio buffer related changes for StoneyVijendar Mukunda2017-10-191-5/+78
| | | | | | | | | | | | | | Stoney uses 16kb SRAM memory for playback and 16Kb for capture.Modified Max buffer size to have the correct mapping between System Memory and SRAM. Added snd_pcm_hardware structures for playback and capture for Stoney.

* ASoC: AMD: DMA driver changes for Stoney PlatformVijendar Mukunda2017-10-191-22/+65
| | | | | | | | | | | | | | | | | Added DMA driver changes for Stoney platform. Below are the key differences between Stoney and CZ In Stoney, Memory Gating is disabled.SRAM Banks won't be turned off.No Of SRAM Banks reduced to 6. DAGB Garlic Interface used and 16 bit resolution is supported. SRAM bank 1 & SRAM bank 2 will be used for playback scenario. SRAM Bank 3 & SRAM Bank 4 will be used for Capture scenario.

| | | | | | | | | | | | | For Stoney platform, Memory gating is disabled.i.e SRAM Banks won't be turned off. By Default, SRAM Bank state set to ON. Added condition checks to skip SRAM Bank state set logic for Stoney platform.

* ASoC: constify snd_pcm_ops structuresJulia Lawall2016-09-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct snd_pcm_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_platform_driver e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i; expression e1, e2; position p; @@ snd_pcm_set_ops(e1, e2, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_pcm_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_pcm_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@kernel.org>

* ASoC: AMD: add AMD ASoC ACP 2.x DMA driverMaruthi Srinivas Bayyavarapu2016-01-101-0/+914
ACP IP has internal DMA controller with multiple channels which can be programmed in cyclic/non cyclic manner. ACP can generate interrupt upon completion of DMA transfer, if required. The PCM driver provides the platform DMA component to ALSA core.
