| | * ASoC: fsl: Remove dependencies of boards for SND_SOC_EUKREA_TLV320Alexander Shiyan2014-06-011-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eukrea-i.MX51 board was converted to use DT, ie we no longer have a MACH_EUKREA_MBIMXSD51_BASEBOARD symbol. Transformation of other boards planned for the near future, so this patch removes all these dependencies and restricts build of this driver to ARCH_MXC.

| * | ASoC: fsl-ssi: Fix baudclock handlingMarkus Pargmann2014-06-011-21/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The baudclock may be used and set by different streams. Allow only the first stream to set the bitclock rate. Other streams have to try to get to the correct rate without modifying the bitclock rate using the SSI internal clock modifiers. The variable baudclk_streams is introduced to keep track of the active streams that are using the baudclock. This way we know if the baudclock may be set and whether we may enable/disable the clock. baudclock enable/disable is moved to hw_params()/hw_free(). This way we can keep track of the baudclock in those two functions and avoid a running clock while it is not used. As hw_params()/hw_free() may be called multiple times for the same stream, we have to use baudclk_streams variable to know whether we may enable/disable the clock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In i2s master mode the fsl_ssi driver depends on someone calling .set_tdm_slot correctly.

| * | ASoC: fsl-ssi: set bitclock in master mode from hw_paramsSascha Hauer2014-06-011-4/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fsl_ssi driver uses the .set_sysclk callback to configure the bitclock for master mode. This is unnecessary since the bitclock is known in hw_params. This patch configures the bitclock from .hw_params. .set_dai_sysclk now sets a bitclock frequency which is preferred over the default calculated bitclock frequency.

As these settings depend on the combination of codec and cpu DAI, this should really be done by sound cards. This patch removes fsl_ssi_setup() and adds the missing register setups to fsl_ssi_set_dai_fmt(). It also removes all calls to fsl_ssi_setup().

| | | | * | ASoC: fsl_sai: Fix buggy configurations in trigger()Nicolin Chen2014-04-142-18/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current trigger() has two crucial problems: 1) The DMA request enabling operations (FSL_SAI_CSR_FRDE) for Tx and Rx are now totally exclusive: It would fail to run simultaneous Tx-Rx cases. 2) The TERE disabling operation depends on an incorrect condition -- active reference count that only gets increased in snd_pcm_open() and decreased in snd_pcm_close(): The TERE would never get cleared. So this patch overwrites the trigger function by following these rules: A) We continue to support tx-async-while-rx-sync-to-tx case alone, which's originally limited by this fsl_sai driver, but we make the code easy to modify for the further support of the opposite case. B) We enable both TE and RE for PLAYBACK stream or CAPTURE stream but only enabling the DMA request bit (FSL_SAI_CSR_FRDE) of the current direction due to the requirement of SAI -- For tx-async-while-rx-sync-to-tx case, the receiver is enabled only when both the transmitter and receiver are enabled. Tested cases: a) aplay test.wav -d5 b) arecord -r44100 -c2 -fS16_LE test.wav -d5 c) arecord -r44100 -c2 -fS16_LE -d5 | aplay d) (aplay test2.wav &); sleep 1; arecord -r44100 -c2 -fS16_LE test.wav -d1 e) (arecord -r44100 -c2 -fS16_LE test.wav -d5 &); sleep 1; aplay test.wav -d1 Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Acked-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>

This unfortunately leads to a link error if one or both of them are built-in, while the imx-pcm-dma framework is a loadable module: sound/built-in.o: In function `fsl_ssi_probe': :(.text+0x51fb8): undefined reference to `imx_pcm_dma_init' sound/built-in.o: In function `fsl_spdif_probe': :(.text+0x52e20): undefined reference to `imx_pcm_dma_init' This changes Kconfig to prevent this case by using 'select' to turn on the imx-pcm-dma code from both drivers. For consistency, we also turn on the imx-pcm-fiq code, which is an alternative to the dma implementation. Note that imx-pcm-fiq is platform dependent, so we must not enable that unless we are building a kernel for i.MX. Note also the "if SND_IMX_SOC != n" syntax as opposed to the normal "if SND_IMX_SOC". This is needed to avoid turning on the options as 'm' if 'SND_IMX_SOC' is a module. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mark Brown <broonie@linaro.org>
