[ Upstream commit 8c716f80dfe8cd6ed9a2696847cea1affeeff6ff ]
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.
