# \[PATCH v2 4/7\] imx-drm: ipuv3-crtc: Implement mode\_fixup - From: Steve Longerbeam \ - Date: 2014-12-19 02:02:50 - List: linux-fbdev - Page: https://ratatoskr.run/linux-fbdev/2014/12/4397636 - Thread: https://ratatoskr.run/dri-devel/2014/12/4397628/t.md ```text Ask the IPU display interface, via ipu_di_adjust_videomode(), to adjust a video mode to meet any DI restrictions. The function takes a subsystem independent videomode, so the drm_display_mode must be converted to videomode first, and then the adjusted mode converted back to a drm_display_mode.
