This patch the I2C board information for the WM8994 used in the Aquila as audio codec and adds the I2C/I2S platform drivers. Additionlly, to control power consumption have registerd the voltage consumer of WM8994 to the regulator framework. I initialize gpio settting relevant to operation of audio codec. I explain following comment concering gpio setting: - CODEC_XTAL_EN : This gpio enables that the main clock is provided to operate audio codec. - MICBIAS_EN : This gpio enable the microphone to input analog - ADC_EN : This gpio enable the ADC device which is used to detect the kind of jack. (SND_JACK_HEADPHONE/HEADSET/MECHANICAL/AVOUT) According to the kind of jack, an electric current is changed.
