Subject: [PATCH v3 5/7] arm64: dts: allwinner: Add SPDIF node for Allwinner H6
Date: Sat, 25 May 2019 18:23:21 +0200	[thread overview]
Message-ID: <20190525162323.20216-6-peron.clem@gmail.com> (raw)
In-Reply-To: <20190525162323.20216-1-peron.clem@gmail.com>

The Allwinner H6 has a SPDIF controller called OWA (One Wire Audio).

Only one pinmuxing is available so set it as default.
