From af22f647b4a0b4a549ccbbc55a324edc54089564 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Mon, 22 Feb 2016 01:54:46 +0000 Subject: [PATCH] video: fbdev: pmag-ba-fb: Fix the lower margin size According to the board specification[1] the width of the vertical sync front porch is 12 pixels or the same as the width of the horizontal sync front porch. This in turn means the size of the lower margin is 0, because the vertical sync starts as soon as the start of the horizontal sync terminates the last line.
