The board is using McASP2 for both analog (tlv320aic3106) and HDMI (SiI9022) audio. 12.288MHz oscillator provides the MCLK for both aic3106 and SiI9022. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> --- Hi, Changes since v1: - Rename the sii9022_mclk ficed clock to aud_mclk (as it is named in the schema) and use it within the sound card dai nodes for the codecs.
