From 36bddb2021d5edddf08081ee473f80cf1fc7f0e4 Mon Sep 17 00:00:00 2001 From: Alex Bee Date: Fri, 18 Jun 2021 20:12:56 +0200 Subject: [PATCH] arm64: dts: rockchip: add SPDIF node for ROCK Pi 4 [ Upstream commit 697dd494cb1cf56acfb764214a1e4788e4d1a983 ] Add a SPDIF audio-graph-card to ROCK Pi 4 device tree. It's not enabled by default since all dma channels are used by the (already) enabled i2s0/1/2 and the pin is muxed with GPIO4_C5 which might be in use already. If enabled SPDIF_TX will be available at pin #15.
