X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=34ea5342bd6da63f666215c4ef4b7b3948511c14;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: Dove: Add the audio device to the Cubox DT

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.
