    Subject[PATCH 4.4 061/134] coresight: Fixes coresight DT parse to get correct output port ID.
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

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

    From: Mike Leach <mike.leach@linaro.org>


    [ Upstream commit eeedc5421dd3b51de73e6106405c5c77f920f281 ]

    Corrected to get the port numbering to allow programmable replicator driver
    to operate correctly.

    By convention, CoreSight devices number ports, not endpoints in
    the .dts files:-

    port {
    reg<N>
    endpoint {
    }
    }

    Existing code read endpoint number - always 0x0, rather than the correct
    port number.
