* ASoC: samsung: odroid: Ensure proper sample rate on pri/sec PCMSylwester Nawrocki2019-02-181-0/+56
| | | | | | | | | | | | | | Currently when playing sound with different sample rates actual sample rate will be determined by audio stream which starts first on either primary or secondary PCM. The audio root clock will be configured appropriately only for the first stream. As the hardware is limited to same sample rate on both interfaces we need to disallow streams with different sample rates. It is done by this patch by returning error in FE hw_params if there is already active stream running with different sample rate.

* ASoC: codecs: ad193x: Add support to disable on-chip PLLCodrin Ciubotariu2019-02-182-1/+33
| | | | | | | | | | | The on-chip PLL can be disabled if on the MCLKI pin we have an external clock at 512 x fs. This clock can be used as direct internal clock for ADCs or DACs. To support this, we add an extra clock id that can be configured using the set_sysclk() callback.

* ASoC: codecs: ad193x: Add runtime support for DSP_A and I2S modesCodrin Ciubotariu2019-02-181-2/+7
| | | | | | | | | | | The driver only supports DPS_A for DAC, which is configured at probe. This patch adds support for DSP_A and I2S modes by using the set_fmt() callback.

* ASoC: codecs: ad193x: Fix frame polarity for DSP_A formatCodrin Ciubotariu2019-02-181-0/+6
| | | | | | | | | | By default, the codec starts to interpret the left (first) channel on the falling edge (low polarity) of LRCLK. However, for DSP_A, the left channel needs to start on the rising edge of LRCLK. This patch fixes this channel swap by toggling the bit which selects the LRCLK polarity.

* ASoC: da7219: Update TDM usage to be more flexibleAdam Thomson2019-02-141-33/+47
| | | | | | | | | | | | | | | | | | | | | The previous implementatation was restrictive with regards to BCLK rates for slave mode where the driver would not allow rates the codec couldn't provide itself as clock master. The codec is able to automatically determine and handle whatever rate is provided so this restriction isn't necessary for slave mode. The code was also flawed with regards to setting of the frame offset as using rx_mask to explicitly set the offset has the knock on effect of impacting the min and max channels for the codec, in soc_pcm_hw_params() through the call to soc_pcm_codec_params_fixup(). With this update, the driver now only limits frame size if codec is clock master, and dynamically determines the BCLK offset relating to WCLK using the tx_mask for slot offset along with the slot width provided.

* ASoC: da7219: Add support for master mode BCLK rate adjustmentAdam Thomson2019-02-142-10/+27
| | | | | | | | | | | | Previously the driver would default the BCLK periods per WCLK to 64, to cover all possible non-TDM scenarios when the codec was DAI clock master. However some devices require a lower BCLK rate to operate correctly so with this in mind, this commit updates the code to be more dynamic, with BCLK rate now based on SR and word length provided to hw_params().

| | | | | | | | | | | | | | | This is a part of conversion of Samsung platforms to use the custom DMA config for specifying DMA channel names, in addition to passing custom DMA device for the secondary CPU DAI's "PCM" component for some variants of the I2S controller. We also don't set the SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME any more as setting it wouldn't allow to specify DMA channels through the custom DMA config.

| | | | | | | | | | | | | This patch adds DPCM links in order to support the secondary I2S interface. For the secondary PCM interface to be actually available one more entry should be added to the sound-dai property in sound/cpu node in DT. The changes in driver are done in a way so we are backwards compatible with existing DTS/DTB, i.e. if the cpu sound-dai property contains only one entry only one PCM will be registered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 4d230d1271064 ("ASoC: rsnd: fixup not to call clk_get/set under non-atomic") added new rsnd_ssi_prepare() and moved rsnd_ssi_master_clk_start() to .prepare. But, ssi user count (= ssi->usrcnt) is incremented at .init (= rsnd_ssi_init()). Because of these timing exchange, ssi->usrcnt check at rsnd_ssi_master_clk_start() should be adjusted. Otherwise, 2nd master clock setup will be no check. This patch fixup this issue.
