From 028cd86b794f4a7f09525587c8e9ab6b03a6fa0f Mon Sep 17 00:00:00 2001 From: Darren Etheridge <detheridge@ti.com> Date: Fri, 23 Aug 2013 16:52:53 -0500 Subject: [PATCH] video: da8xx-fb: fix the polarities of the hsync/vsync pulse The polarities were being set to active low when fbdev was requesting active high. This patch reverses it so that what is set into the LCD controller is correct.
