The CRTC's mode-setting code contains quite a bit of code that belongs to the planes or various encoder chips. This patchset refactors these bits and moves things to the correct places. With the patches applied, the remaining DPMS function will be gone and its content be moved. Several code duplications will be removed. There was also a bugfix wrt the VGA SCREEN_DISABLE bit, but it's unclear if the bug had any effect in practice. Tested with AST2100 and AST2600 with VGA and DP outputs.
