2020-04-21ASoC: uniphier: use snd_compress_opsKuninori Morimoto1-1/+1
We can use snd_compress_ops. Let's switch to use it.

2020-01-21ASoC: uniphier: move .suspend/.resume to componentKuninori Morimoto1-2/+0
There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC. Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary. This patch moves DAI driver .suspend/.resume to Component driver Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/87zhejx7j4.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
2019-08-20ASoC: uniphier: Fix double reset assersion when transitioning to suspend stateKunihiko Hayashi1-0/+1
When transitioning to supend state, uniphier_aio_dai_suspend() is called and asserts reset lines and disables clocks. However, if there are two or more DAIs, uniphier_aio_dai_suspend() are called multiple times, and double reset assersion will cause. This patch defines the counter that has the number of DAIs at first, and whenever uniphier_aio_dai_suspend() are called, it decrements the counter. And only if the counter is zero, it asserts reset lines and disables clocks. In the same way, uniphier_aio_dai_resume() are called, it increments the counter after deasserting reset lines and enabling clocks.

2018-07-30ASoC: uniphier: change functions to staticKatsuhiro Suzuki1-3/+0
This patch changes some functions that are not used by other objects to static. Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-07-30ASoC: uniphier: add support for multichannel outputKatsuhiro Suzuki1-0/+3
This patch adds multichannel PCM output support for LD11/LD20. Currently driver tested and supported only 2ch, 6ch, and 8ch. Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-05-09ASoC: uniphier: add digital output volume for UniPhier sound systemKatsuhiro Suzuki1-0/+7
This patch adds controllers for digital volume of PCM output. Volume effects simply linear, not dB scale as follows: Gained PCM = Original * 0x4000 / Volume The value range of volume is from 0x0001 to 0xffff. 0x0000 works as mute. Initial value is 0x4000 (+0dB). Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-04-27ASoC: uniphier: remove boilerplate from lisence commentKatsuhiro Suzuki1-13/+0
This patch removes boilerplate of GPLv2, use only SPDX identifier as same as other recently ASoC DAI drivers. Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-03-19ASoC: uniphier: add syscon property for UniPhier sound systemKatsuhiro Suzuki1-0/+2
This patch adds syscon property for specifying soc-glue core. Currently, soc-glue core is used for changing the state of S/PDIF signal output pin to signal output state or Hi-Z state. After resetting of SoC Hi-Z state is selected. This driver set to signal output state when syscon property is available.

2018-02-12ASoC: uniphier: add support for UniPhier AIO CPU DAI driverKatsuhiro Suzuki1-0/+9
This patch adds CPU DAI driver for UniPhier AIO audio sound system. This module provides PCM devices for all input/output port of AIO such as I2S, S/PDIF. Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-02-12ASoC: uniphier: add support for UniPhier AIO DMA driverKatsuhiro Suzuki1-0/+2
This patch adds supports for UniPhier AIO DMA. This module shared register area with all sound devices for I2S, S/PDIF and so on. Since the AIO has mixed register map for those I/Os, it is hard to split register areas for each sound devices.

2018-02-12ASoC: uniphier: add support for UniPhier AIO common driverKatsuhiro Suzuki1-0/+343
This patch adds common functions for UniPhier AIO audio sound system. This provides commonly used APIs for input/output control registers for UniPhier AIO. This module provides all sound devices for I2S, S/PDIF and so on. Since the AIO has mixed register map for those I/Os, it is hard to split register areas for each sound devices.
