    Subject[PATCH 3.16 150/217] drm/radeon: add a dpm quirk for all R7 370 parts
    3.16.35-rc1 review patch.  If anyone has any objections, please let me know.

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

    From: Alex Deucher <alexander.deucher@amd.com>

    commit 0e5585dc870af947fab2af96a88c2d8b4270247c upstream.

    Higher mclk values are not stable due to a bug somewhere.
    Limit them for now.
