ASoC: TWL6040: Add twl6040 codec driver 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.

ASoC: twl6040: Move PLL selection to codec driver It is better if the selection between the Low power, and High performance PLL is handled within the codec driver, not in machine driver(s) to avoid duplicated code, and also to have consistent tracking of the selected PLL, and the resulting differences in supported sample rates.
