Subject: drm/radeon/dpm: select the appropriate vce power state for KV/KB/ML
From: Alex Deucher <[email protected]>
commit c83dec3bb6c38629398b65c231c80978b3e00e14 upstream.
Compare the clock in the limits table to the requested evclk rather
than just taking the first value. Improves vce performance in certain
cases.
