Subject: [PATCH 4/6] imx-drm: ipuv3-crtc: Implement mode_fixup
Date: Mon, 15 Dec 2014 16:29:22 -0800	[thread overview]
Message-ID: <1418689764-11276-5-git-send-email-slongerbeam@gmail.com> (raw)
In-Reply-To: <1418689764-11276-1-git-send-email-slongerbeam@gmail.com>

From: Steve Longerbeam <steve_longerbeam@mentor.com>

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.
