    Subject[PATCH 4.4 050/118] ARM: imx6: add missing BM_CLPCR_BYP_MMDC_CH0_LPM_HS setting for imx6ul
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

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

    From: Peter Chen <peter.chen@nxp.com>

    commit f5a49057c71433e35a4712ab8d8f00641b3e1ec0 upstream.

    There is a missing BM_CLPCR_BYP_MMDC_CH0_LPM_HS setting for imx6ul,
    without it, the "standby" mode can't work well, the system can't be
    resumed.

    With this commit, the "standby" mode works well.
