HSYNC, VSYNC and DISP_CLK are very useful display signals for debugging.
Configure them as active pins.
Signed-off-by: Fabio Estevam fabio.estevam@freescale.com --- Changes since v2: - Fix typo in HSYNC Changes since v1: - Add a comment in the code explaining that the purpose of configuring these pins are for debugging
