Set "media_disp2_pix" clock rate to that rate, instead of the original 68.9MHz. The LVDS serial clock is controlled by "media_ldb" clock. It should run at 490MHz(7-fold the pixel clock rate due to single LVDS link). Set "video_pll1" clock rate and "media_ldb" to 490MHz to achieve that. This should be able to suppress this LDB driver warning: [ 17.206644] fsl-ldb 32ec0000.blk-ctrl:bridge@5c: Configured LDB clock (70000000 Hz) does not match requested LVDS clock: 490000000 Hz This also makes the display mode used by the panel pass mode validation against pixel clock rate and "media_ldb" clock rate in a certain display driver.
