Subject: [PATCH v5 1/3] arm64: dts: allwinner: Add SPDIF node for Allwinner H6
Date: Sun, 11 Aug 2019 22:31:42 +0200 [thread overview]
Message-ID: <20190811203144.5999-2-peron.clem@gmail.com> (raw)
In-Reply-To: <20190811203144.5999-1-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.
Signed-off-by: Clément Péron <peron.clem@gmail•com>
