The X11 will display either shifted image or otherwise distorted image on the LCD. The problem is that the X11 tries to reconfigure the framebuffer and along the way calls fb_ops.fb_set_par() with X11's desired configuration values. The field of particular interest is fb_info->var.sync which contains non-standard values if configured by kernel. These are either FB_SYNC_DATA_ENABLE_HIGH_ACT, FB_SYNC_DOTCLK_FAILING_ACT or both, depending on the platform configuration. Both of these values are defined in the include/linux/mxsfb.h file. The driver interprets these values and configures the LCD controller accordingly. Yet X11 only has access to the standard values for this field defined in include/uapi/linux/fb.h and thus, unlike kernel, omits these special values. This results in distorted image on the LCD. This patch moves these non-standard values into new field of the mxsfb_platform_data structure so the driver can in turn check this field instead of the video mode field for these specific portions. Moreover, this patch prefixes these values with MXSFB_SYNC_ prefix instead of FB_SYNC_ prefix to prevent confusion of subsequent users.
