Subject: drm/amdgpu/dce11: update pll programming for ELM/BAF
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=22f0c5bd14f6cc8d60dbfc736f632fc891f1b0f9;p=openwrt%2Fstaging%2Fblogic.git

drm/amdgpu/dce11: update pll programming for ELM/BAF

SetPixelClock table handles pll divider calculation and
spread spectrum setup, so no need to use calculate the
dividers and call the ss enable cmd table.
