    OMAPDSS: DPI: Add locking for DPI interface · c8a5e4e8
    Archit Taneja authored
    The DPI interface driver currently relies on the panel driver to ensure calls
    like omapdss_dpi_display_enable() and omapdss_dpi_display_disable() are executed
    sequentially. Also, currently, there is no way to protect the DPI driver data.
    All DPI panel drivers don't ensure this, and in general, a DPI panel driver
    should use it's lock to that ensure it's own driver data and omap_dss_device
    states are taken care of, and not worry about the DPI interface.
    Add mutex locking in the DPI enable/disable/set_timings ops.
