    OMAPDSS: DPI: widen the pck search when using dss fck · 2c6360fb
    Tomi Valkeinen authored
    When not using DSI PLL to generate the pixel clock, but DSS FCK, the
    possible pixel clock rates are rather limited. DSS FCK is currently used
    on OMAP2 and OMAP3.
    When using Beagleboard with a monitor that supports high resolutions,
    the clock rates do not match (at least for me) for the monitor's pixel
    clocks within the current threshold in the code, which is +/- 1MHz.
    This patch widens the search up to +/- 15MHz. The search is done in
    steps, i.e. it first tries to find a rather exact clock, than a bit less
    exact, etc. so this should not change the cases where a clock was
    already found.
