[PATCH 16/16] drm/amd/display: Clean up for DCN1 clock debug logging
sunpeng.li at amd.com
sunpeng.li at amd.com
Thu Nov 29 15:52:23 UTC 2018
From: Fatemeh Darbehani <fatemeh.darbehani at amd.com>
[Why]
To prepare for clock debug logging. With the exception of removing
max_supported_dppclk_khz from logs, there are no functional changes.
[How]
Add clk_bypass struct and clean up buffer logic
