* ASoC: samsung: odroid: Fix clock configuration for 44100 sample rateSylwester Nawrocki2019-03-131-2/+2
| | | | | | | | | | | | | | | | | After commit fbeec965b8d1c ("ASoC: samsung: odroid: Fix 32000 sample rate handling") the audio root clock frequency is configured improperly for 44100 sample rate. Due to clock rate rounding it's 20070401 Hz instead of 22579000 Hz. This results in a too low value of the PSR clock divider in the CPU DAI driver and too fast actual sample rate for fs=44100. E.g. 1 kHz tone has actual 1780 Hz frequency (1 kHz * 20070401/22579000 * 2). Fix this by increasing the correction passed to clk_set_rate() to take into account inaccuracy of the EPLL frequency properly.

| | | | | | | | | | | | | | | This patch sets missing stream_name of capture part of the DAI driver so we can define DAPM routing properly also for the capture stream. While at it "Playback" suffix is added to the playback stream names to clearly identify playback/capture.

* ASoC: samsung: i2s: Fix multiple "IIS multi" devices initializationSylwester Nawrocki2019-02-192-18/+34
| | | | | | | | | | | | | | | | | | | On some SoCs (e.g. Exynos5433) there are multiple "IIS multi audio interfaces" and the driver will try to register there multiple times same platform device for the secondary FIFO, which of course fails miserably. To fix this we derive the secondary platform device name from the primary device name. The secondary device name will now be <primary_dev_name>-sec instead of fixed "samsung-i2s-sec". The fixed platform_device_id table entry is removed as the secondary device name is now dynamic and device/driver matching is done through driver_override.

| | | | | | | | | | | This fixes unregistration of the secondary platform device so all resources are properly released. Additionally the removal sequence is corrected so it is in reverse order comparing to probe sequence. The test against NULL priv->pdev_sec is removed as it is not necessary.

* 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.

| | | | | | | | | | | | | | | 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.

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.
