    Subject[PATCH 4.4 008/163] ARM: OMAP2: Fix up interconnect barrier initialization for DRA7
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

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

    From: Nishanth Menon <nm@ti.com>

    commit 456e8d53482537616899a146b706eccd095404e6 upstream.

    The following commits:
    commit 3fa609755c11 ("ARM: omap2: restore OMAP4 barrier behaviour")
    commit f746929ffdc8 ("Revert "ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688"")
    and
    commit ea827ad5ffbb ("ARM: DRA7: Provide proper IO map table")
    came in around the same time, unfortunately this seem to have missed
    initializing the barrier for DRA7 platforms - omap5_map_io was reused
    for dra7 till it was split out by the last patch. barrier_init
    needs to be hence carried forward as it is valid for DRA7 family of
    processors as they are for OMAP5.

    Fixes: ea827ad5ffbb7 ("ARM: DRA7: Provide proper IO map table")
