drm/amd/display: remove dc dependencies from SPL library
[Why] Make SPL library dc-independent so it can be reused by other components [How] Create separate set of fixed31_32 calls in SPL Make all inputs and outputs to SPL use primitive types For ratios and inits, return as uint32 from SPL. So add conversion from uint32 back to fixed point in SPL-to-dc translate function Reviewed-by: Relja Vojvodic <relja.vojvodic@amd.com> Signed-off-by: Jerry Zuo <jerry.zuo@amd.com> Signed-off-by: Samson Tam <samson.tam@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
