This patch exposes a helper function to program CIF instance present in various modules. Update Makefile to build tegra_cif.c and build dependency is added over config CONFIG_SND_SOC_TEGRA. Tegra30 and Tegra124 have an identical CIF programming helper function. Remove tegra30_ahub_set_cif(), tegra124_ahub_set_cif() and instead we can rely on common exposed function tegra_set_cif(). Tegra30 and Tegra124 I2S driver uses soc_data to reference different versions of set_audio_cif function via callback function pointer. This is no more required with current patch and hence remove soc_data from i2s driver. Also update variable names for audio and client channels. This is required to avoid wrapping in function tegra_set_cif().

It can interface with I2S compatible devices. Tegra I2S controller can operate as both master and slave. This patch registers I2S controller with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes I2S interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The I2S devices can be enabled in the DT via "nvidia,tegra210-i2s" compatible binding.

From the signal flow perpsective, the DSPK can be viewed as a PDM transmitter that up-samples the input to the desired sampling rate by interpolation then converts the oversampled PCM input to the desired 1-bit output via Delta Sigma Modulation (DSM). This patch registers DSPK component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes DSPK interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The DSPK devices can be enabled in the DT via "nvidia,tegra186-dspk" compatible binding. This driver can be used on Tegra194 chip as well.
