See http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob;f=Documentation/arm/OMAP/DSS omapfb.mode=<xres>x<yres>[M][R][-<bpp>][@<refresh>][i][m] or <name>[-<bpp>][@<refresh>] - Default video mode for specified displays. For example - "dvi:800x400MR-24@60". <xres>, <yres>, <bpp> and <refresh> are decimal numbers and <name> is a string. <xres> is resolution in x-axis. <yres> is resolution in y-axis. <bpp> is bit per pixel. [M] will allow to compute the timings using VESA(tm) Coordinated Video Timings (CVT). [R] will allow to compute with reduced blanking (for flatpanels). [i] will allow to compute interlaced mode. [m] will add margins equal to 1.8% of xres rounded down to 8 pixels, and 1.8% of yres. NOTE: The char 'i' and 'm' must be after 'M' and 'R'. Example: Just for information: 1024x768MR-8@60m = Reduced blank with margins at 60Hz. For more information, See drivers/video/modedb.c. There are also two special modes: "pal" and "ntsc" that can be used to tv out. _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
