    Please let's not add yet another omap specific layer that will
    make it incrementally harder to have generic drivers.

    Instead, we can do the omap specific locking in the
    platform code and then the drivers can use the functions
    passed in the platform_data if they're implemented.

    Regards,

    Tony
