drm/radeon/kms: rework spread spectrum handling
This patch reworks spread spectrum handling to enable it properly on lvds and DP/eDP links. It also fixes several bugs in the old spread spectrum code. - Use the ss recommended reference divider if available when calculating the pll - Use the proper ss command tables on pre-DCE3 asics - Avoid reading past the end of the ss info tables - Enable ss on evergreen asics (lvds, dp, tmds) - Enable ss on DP/eDP links Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
