ASoC: Support TI Isabelle Audio driver The Isabelle Audio IC is a complete low power high fidelity CODEC with integrated ADCs, DACs, decimation and interpolation filters, PLL, and power providers. This device supports 2 analog and 2 digital microphone channels, a mono earpiece driver, stereo class G headphone drivers with ultra low power and best SNR in the industry, stereo Class D speaker drivers, and 2 high performance Line drivers. The below patch is a basic driver code for TI Isabelle audio codec. The functionalities like headset detection, etc., will be included incrementally in the up-coming patches.
