<b>Subject:</b> [PATCH] drm/amd/pp: Send khz clock values to DC for smu7/8</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">The previous change wasn't covering smu 7 and 8 and therefore DC was<br>
seeing wrong clock values.<br>
<br>
This fixes an issue where the pipes seem to hang with a 4k DP and 1080p<br>
HDMI display.<br>
<br>
Fixes: c3df50abc84b ("drm/amd/pp: Convert clock unit to KHz as defined")<br>
