Initial version of TWL6040 codec driver. The TWL6040 codec uses a proprietary PDM-based digital audio interface. Audio paths supported are: - Input: Main Mic, Sub Mic, Headset Mic, Auxiliary-FM Left/Right - Output: Headset Left/Right, Handsfree Left/Right TWL6040 codec supports power-up/down manual and automatic sequence. Manual sequence is done through a specific register writes sequence. Automatic sequence is done when the codec is powered-up through the external AUDPWRON line. The completion of the sequence is signaled through the audio interrupt. TWL6040 codec sysclk can be provided by: low-power or high performance PLL: - The low-power PLL takes a low-frequency input at 32,768 Hz and generates an approximate of 17.64 or 19.2 MHz (for 44.1 KHz and 48 KHz respectively) - The high-performance PLL generates an exact 19.2 MHz clock signal from high-frequency input at 12/19.2/26/38.4 MHz. Low-power playback mode is a special scenario where only headset path (headset DAC and driver) is active. For the particular case of headset path, PLL being used defines the headset power mode: low-power, high-performance.
