I am using imx6q Rev D sabrelite board. Using the Linux kernel version 3.0.35. The board is connected with 3 LCD 4.2", 7.1" and 12.3". On boot up, i am able to rotate the logo to 180 degree using command, "echo 1 > /sys/class/graphics/fb0/rotate" but not able to rotate the logo 90 degree or 270 degree. Please provide your suggestions on how rotation of 90 degree or 270 degree can be accomplished using fb0 rotate.
