This series enables audio playback over u-boot for TI AM62x SoC. It ports MCASP driver which acts as I2S audio signal generator and TLV320AIC3106 which converts the digital audio to analog. Lastly, this also adds sound driver to complete the audio graph and enables audio playback using u-boot command.
Audio can be played over at u-boot prompt using below command : sound play <duration in ms> <frequency> This plays a beep sound for the given duration and of the given frequency.
