    Subject[PATCH 4.4 25/53] drm: rcar-du: lvds: Fix PLL frequency-related configuration
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

    commit 5e1ac3bdc6bbb4f378251b87625b8acfbfc4ae82 upstream.

    The frequency checks don't match the datasheet, fix them.
