    fsl-diu-fb: remove check for pixel clock ranges · 39785eb1
    Timur Tabi authored
    The Freescale DIU framebuffer driver defines two constants, MIN_PIX_CLK and
    MAX_PIX_CLK, that are supposed to represent the lower and upper limits of
    the pixel clock.  These values, however, are true only for one platform
    clock rate (533MHz) and only for the MPC8610.  So the actual range for
    the pixel clock is chip-specific, which means the current values are almost
    always wrong.  The chance of an out-of-range pixel clock being used are also
    remote.
    
    Rather than try to detect an out-of-range clock in the DIU driver, we depend
    on the board-specific pixel clock function (e.g. p1022ds_set_pixel_clock)
    to clamp the pixel clock to a supported value.
