From 3906f8558838841dad2bb96fc6ca10fe54a99f09 Mon Sep 17 00:00:00 2001 From: Torsten Duwe Date: Mon, 10 Nov 2025 19:11:53 +0100 Subject: [PATCH] arm64: dts: rockchip: enable HDMI audio on Rock 5 ITX The Rock 5 ITX only needs enablement for 2 nodes in order to send audio on HDMI1, the connector closer to the 12V barrel jack and farther from S/PDIF. It is sufficient to declare the audio injection as okay, and to activate I2S6. Note that for the other HDMI output it is not that trivial, as the video data there originates from the SoC's DisplayPort output DP1 and is only converted to HDMI in U7 (an RA620).
