[PATCH v3 2/2] ARM: Dove: Add the audio device to the Cubox DT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




This patch activates the audio device of the Cubox.

The audio flow (pin mpp_audio1) is output on both I2S and S/PDIF.

The third si5351 clock (#2, pin mpp13) is used as the external clock.
