ASoC: Add WM8994 CODEC driver The WM8994 is a highly integrated ultra-low power hi-fi audio subsystem designed for smartphones and other portable devices rich in multimedia features. It provides advanced digital mixing facilities enabling low power high quality interconnection of CPU, baseband and other audio sources through flexible digital and analogue routing, and integrates a class W headphone driver and stereo class D speaker drivers.

ASoC: Implement WM8994 OPCLK support The WM8994 can output a clock derived from its internal SYSCLK, called OPCLK. The rate can be selected as a sysclk, with a division from the SYSCLK rate specified (multiplied by 10 since a division of 5.5 is supported) and the clock can be disabled by specifying a divisor of zero.

ASoC: Support FLL input clock selection on WM8994 The WM8994 FLL can be clocked from one of four inputs, the two MCLKs and the LRCLK and BCLK of the AIF associated with the FLL. Allow all four inputs to be used rather than defaulting to MCLK1. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

ASoC: Implement interrupt based WM8994 microphone detection Support interrupt based microphone bias detection. The WM8994 has two microphone bias supplies, with detection supported on both. Detection using GPIOs together with the standard GPIO based jack framework is already supported via the platform data for the WM8994 core driver. Note that as well as the microphone bias itself the system clock and whichever AIF clock is supplying the system clock will need to be enabled for detection to function.
