From 0c460a55dd97b639202d6152979669c8951522cd Mon Sep 17 00:00:00 2001 From: Steve Longerbeam Date: Thu, 18 Dec 2014 18:00:23 -0800 Subject: [PATCH] imx-drm: ipuv3-crtc: Implement mode_fixup 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.
