From d6d756d3ea21a5f50df13503fe38f5655e97ac7f Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 15 Apr 2025 20:01:31 -0500 Subject: [PATCH] arm64: dts: imx8mn-beacon: Set SAI5 MCLK direction to output for HDMI audio [ Upstream commit a747c4dd2a60c4d0179b372032a4b98548135096 ] The HDMI bridge chip fails to generate an audio source due to the SAI5 master clock (MCLK) direction not being set to output. This prevents proper clocking of the HDMI audio interface. Add the `fsl,sai-mclk-direction-output` property to the SAI5 node to ensure the MCLK is driven by the SoC, resolving the HDMI sound issue.
