    ASoC: tegra: Add Tegra210 based ADMAIF driver · f74028e1
    Sameer Pujar authored
    ADMAIF is the interface between ADMA and AHUB. Each ADMA channel that
    sends/receives data to/from AHUB must intreface through an ADMAIF channel.
    ADMA channel sending data to AHUB pairs with an ADMAIF Tx channel and
    similarly ADMA channel receiving data from AHUB pairs with an ADMAIF Rx
    channel. Buffer size is configurable for each ADMAIF channel, but currently
    SW uses default values.
    
    This patch registers ADMAIF driver with ASoC framework. The component
    driver exposes DAPM widgets, routes and kcontrols for the device. The DAI
    driver exposes ADMAIF 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 ADMAIF device can be enabled in the DT via
    "nvidia,tegra210-admaif" compatible binding.
    
    Tegra PCM driver is updated to expose required PCM interfaces and
    snd_pcm_ops callbacks.
