2017-08-17ASoC: bcm: make snd_soc_dai_driver constBhumika Goyal1-1/+1
Make this const as it is only used during a copy operation. Done using Coccinelle. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-08-15ASoC: cygnus: Add support for 384kHz frame ratesLori Hikichi1-180/+55

2016-11-02ASoC: bcm: add depends on HAS_DMAScott Branden1-0/+1
add depends on HAS_DMA to Kconfig. This fixes error reported by kbuild test robot when building for ARCH=m32r: ERROR: "bad_dma_ops" [sound/soc/bcm/snd-soc-cygnus.ko] undefined! Signed-off-by: Scott Branden <scott.branden@broadcom.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-05-31ASoC: cygnus: Add Cygnus audio DMA driverSimran Rai3-0/+875
This patch adds Cygnus audio DMA driver. It supports playback and capture modes and uses ringbuffers for data transfer.

2016-05-31ASoC: cygnus: Add Cygnus audio DAI driverSimran Rai2-0/+1668
This patch adds Cygnus audio DAI driver. It supports I2S, TDM and SPDIF modes and uses three clocks derived from PLL. This patchset has been tested on Cygnus wireless audio bcm958305K board.

2016-04-27ASoC: bcm2835: Add S16_LE support via packed DMA transfersMatthias Reichl1-0/+9
The bcm2835-i2s driver already has support for the S16_LE format but that format hasn't been made available because dmaengine_pcm didn't support packed data transfers. bcm2835-i2s needs 16-bit left+right channel data to be packed into a 32-bit word, the FIFO register is 32-bit only and doesn't support 16-bit access. Now that dmaengine_pcm supports packed transfers the format can be made available by setting the SND_DMAENGINE_PCM_DAI_FLAG_PACK flag. No further configuration is necessary: - snd_dmaengine_dai_dma_data.addr_width is already set to DMA_SLAVE_BUSWIDTH_4_BYTES to force 32-bit DMA transfers - dmaengine_pcm will pick up the S16_LE format from the DAI configuration and make it available since it's no longer masked out due to the PACK flag. - there are no further corner cases to catch in hw_params, since the channel count is fixed at 2 we always have two 16-bit stereo samples that can be transferred via 32-bit DMA Signed-off-by: Matthias Reichl <hias@horus.com> Tested-by: Martin Sperl <kernel@martin.sperl.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-04-25ASoC: bcm2835: setup clock only if CPU is clock masterMatthias Reichl1-2/+9

2016-01-15ASoC: bcm2835: move to use the clock frameworkMartin Sperl1-220/+64
Since the move to the new clock framework with commit 94cb7f76caa0 ("ARM: bcm2835: Switch to using the new clock driver support.") this driver was no longer functional as it was manipulating the clock registers locally without going true the framework. This patch moves to use the new clock framework and also moves away from the hardcoded address offsets for DMA getting the dma-address directly from the device tree. Note that the optimal bclk_ratio selection to avoid jitter due to the use of fractional dividers, which is in the current version has been removed, because not all devices support these non power of 2 sized transfers, which resulted in lots of (downstream) modules that use: snd_soc_dai_set_bclk_ratio(cpu_dai, sample_bits * 2); Signed-off-by: Martin Sperl <kernel@martin.sperl.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-01-09ASoC: bcm: Remove obsoleted Kconfig dependencyTakashi Iwai1-1/+0
CONFIG_SND_SOC_DMAENGINE_PCM was renamed to CONFIG_SND_DMAENGINE_PCM recently. And yet we don't have to select it since CONFIG_SND_GENERIC_DMAENGINE_PCM selects the dependency by itself, so just rip it off.
