Subject: [PATCH 225/752] ARM/dts: am335x-evmsk: Audio support
|
|
|
|
AM335x EVM-SK have only support for audio playback (stereo jack on the
|
|
board) via tlv320aic3106 codec connected to McASP1.
|
|
Enable the support for audio playback on the board:
|
|
- McASP1 configuration
|
|
- tlv320aic3106 configuration
|
|
- Machine driver.
