Subject: [PATCH v2] arm64: dts: rockchip: add SPDIF node for rk3399-rockpro64
Date: Mon, 10 Aug 2020 18:16:19 +0900 [thread overview]
Message-ID: <20200810091619.3170534-1-katsuhiro@katsuster.net> (raw)
This patch adds 'disabled' SPDIF sound node and related settings
for rk3399-rockpro64.
There are 2 reasons:
- All RK3399 dma-bus channels have been already used by I2S0/1/2
- RockPro64 does not have SPDIF optical nor coaxial connector,
just have 3pins
Signed-off-by: Katsuhiro Suzuki <katsuhiro@katsuster.net>

Changes in v2:
- Remove redundant status property
