[PATCH 0/2] drm/msm: fix mismatch between power and frequency
Posted by yuanjie yang 4 weeks, 1 day ago
From: Yuanjie Yang <yuanjie.yang@oss.qualcomm.com>

During DPU runtime suspend, calling dev_pm_opp_set_rate(dev, 0) drops
the MMCX rail to MIN_SVS while the core clock frequency remains at its
original (highest) rate. When runtime resume re-enables the clock, this
may result in a mismatch between the rail voltage and the clock rate.
