Subject: arm64: dts: allwinner: h616: Add SPDIF device node
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fe5128a11f9b5c41a0d8ab8c30c93814a9d47cd6;p=linux.git

arm64: dts: allwinner: h616: Add SPDIF device node

The H616 SoC has an SPDIF transmitter hardware block, which has the same
layout as the one in the H6, minus the receiver side.

Add a device node for it, and a default pinmux.
