[PATCH 5/6] ARM: sun8i: a83t: Add device node for SPDIF transmitter

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

 




The A83T SoC has an SPDIF transmitter block. According to the vendor
BSP kernel, it is compatible with the one found on the H3 SoC.

Add a device node and pinmux setting for it.
