ALSA: ASoC: Add WM8903 CODEC driver
The WM8903 is a high performance ultra-low power stereo CODEC optimised for portable audio applications. Features include: * 5mW power consumption for DAC to headphone playback * Stereo DAC SNR 96dB typical, THD -86dB typical * Stereo ADC SNR 93dB typical, THD -80dB typical * Up to 3 single ended inputs per stereo channel * Up to 2 pseudo differential inputs per stereo channel * Up to 1 fully differential mic input per stereo channel * Digital Dynamic Range Controller (compressor/limiter) * Digital sidetone mixing Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
