Subject: [PATCH 1/1] ARM: mach-imx: pm-imx6: add missing BM_CLPCR_BYP_MMDC_CH0_LPM_HS setting for imx6ul
Date: Tue, 9 Aug 2016 16:24:43 +0800 [thread overview]
Message-ID: <1470731083-26213-1-git-send-email-peter.chen@nxp.com> (raw)
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.
