    Subject[PATCH AUTOSEL 3.18 49/98] drivers: bus: check cci device tree node status
    Date
    From: Abhilash Kesavan <a.kesavan@samsung.com>

    [ Upstream commit 896ddd600ba4a3426aeb11710ae9c28dd7ce68ce ]

    The arm-cci driver completes the probe sequence even if the cci node is
    marked as disabled. Add a check in the driver to honour the cci status
    in the device tree.
