Subject[PATCH v2] ARM: dts: keystone-k2g-evm: add HDMI and analog audio data
Date
The board is using McASP2 for both analog (tlv320aic3106) and
HDMI (SiI9022) audio.
12.288MHz oscillator provides the MCLK for both aic3106 and SiI9022.

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.

Regards,
Peter
