2020-01-21ASoC: cirrus: ep93xx-i2s: move .suspend/.resume to componentKuninori Morimoto1-8/+8
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/87a76jym4p.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>

2019-04-29ARM: ep93xx: move pinctrl interfaces into include/linux/socArnd Bergmann1-2/+1
ep93xx does not have a proper pinctrl driver, but does things ad-hoc through mach/platform.h, which is also used for setting up the boards. To avoid using mach/*.h headers completely, let's move the interfaces into include/linux/soc/. This is far from great, but gets the job done here, without the need for a proper pinctrl driver.

2018-05-11ASoC: cirrus: i2s: IRQ-based stream watchdogAlexander Sverdlin1-0/+68
I2S controller on EP93xx seems to have undocumented HW issue. According to "EP93xx User’s Guide", controller can handle underflow and either transmit last sample or zeroes in such case until FIFO is filled again. In reality undeflow conditions seem to confuse internal state machine from time to time and the whole stream gets shifted by one byte (as captured by logic analyser on the I2S outputs). One could only hear noise instead of original stream and this continues until the FIFO is disabled and enabled again. Work this around by watching underflow interrupt and resetting I2S TX channel + fill FIFO with zero samples until DMA catches up again. This is a nasty workaround, but it works. Hence, Kconfig option to disable it in case of problems. Signed-off-by: Alexander Sverdlin <alexander.sverdlin@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-05-11ASoC: cirrus: i2s: Stop enabling I2S2 and I2S3 FIFOsAlexander Sverdlin1-8/+4
The driver never supported more than 2 channels because of ep93xx_i2s_dma_data[] supporting only 1 DMA channel in each direction. Stop enabling two unused I2S controller FIFOs, this will simplify future interrupt support.

2018-05-01ASoC: cirrus: i2s: Fix {TX|RX}LinCtrlData setupAlexander Sverdlin1-8/+10
According to "EP93xx User’s Guide", I2STXLinCtrlData and I2SRXLinCtrlData registers actually have different format. The only currently used bit (Left_Right_Justify) has different position. Fix this and simplify the whole setup taking into account the fact that both registers have zero default value. The practical effect of the above is repaired SND_SOC_DAIFMT_RIGHT_J support (currently unused).

2018-05-01ASoC: cirrus: i2s: Fix LRCLK configurationAlexander Sverdlin1-4/+4
The bit responsible for LRCLK polarity is i2s_tlrs (0), not i2s_trel (2) (refer to "EP93xx User's Guide"). Previously card drivers which specified SND_SOC_DAIFMT_NB_IF actually got SND_SOC_DAIFMT_NB_NF, an adaptation is necessary to retain the old behavior.

2013-12-18ASoC: ep93xx: remove custom DMA alloc compat functionStephen Warren1-2/+12
ep93xx_compat_request_channel() is almost identical to dmaengine_pcm_compat_request_channel(), with the exception that the latter: a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data pointer rather than some custom type. b) dma_data->filter_data rather than dma_data should be passed to snd_dmaengine_pcm_request_channel() as the filter data. Make minor changes to the ep93xx DAI drivers so that those two conditions are met. This allows removal of the custom .compat_request_channel().

Modify the ep93xx PCM driver so that it's a utility library that can be registered on each DAI, rather than a separate struct device. This is more in line with how many recent DT-converted platforms operate, and avoids the need for yet another struct device.

2013-03-26ASoC: ep93xx: Use ep93xx_dma_params instead of ep93xx_pcm_dma_paramsLars-Peter Clausen1-6/+6
Currently the ep93xx_dma_params struct which is passed to the dmaengine driver is constructed at runtime from the ep93xx_pcm_dma_params that gets passed to the ep93xx PCM driver from one of the ep93xx DAI drivers. The ep93xx_pcm_dma_params struct is almost identical to the ep93xx_dma_params struct. The only missing field is the 'direction' field, which is computed at runtime in the PCM driver based on the current substream. Since we know in advance which ep93xx_pcm_dma_params struct is being used for which substream at compile time, we also already know which direction to use at compile time. So we can easily replace all instances of ep93xx_pcm_dma_params with their ep93xx_dma_params counterpart. This allows us to simplify the code in the ep93xx pcm driver quite a bit.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This contains pretty many small commits covering fairly large range of files in sound/ directory. Partly because of additional API support and partly because of constantly developed ASoC and ARM stuff. Some highlights: - Introduced the helper function and documentation for exposing the channel map via control API, as discussed in Plumbers; most of PCI drivers are covered, will follow more drivers later - Most of drivers have been replaced with the new PM callbacks (if the bus is supported) - HD-audio controller got the support of runtime PM and the support of D3 clock-stop. Also changing the power_save option in sysfs kicks off immediately to enable / disable the power-save mode. - Another significant code change in HD-audio is the rewrite of firmware loading code. Other than that, most of changes in HD-audio are continued cleanups and standardization for the generic auto parser and bug fixes (HBR, device-specific fixups), in addition to the support of channel-map API. - Addition of ASoC bindings for the compressed API, used by the mid-x86 drivers. - Lots of cleanups and API refreshes for ASoC codec drivers and DaVinci. - Conversion of OMAP to dmaengine. - New machine driver for Wolfson Microelectronics Bells. - New CODEC driver for Wolfson Microelectronics WM0010. - Enhancements to the ux500 and wm2000 drivers - A new driver for DA9055 and the support for regulator bypass mode."
