Summary: rtc wake up from standby mode fails on bf537 with adv7393 installed
Details:
Run video_test in the background, and rtc wake up from standby mode fails on bf537-stamp with adv7393 driver installed.
Config is attached.
Because test machine had been changed, so I can not find the last passed version. First failed version is:

This bug is caused by:
[uclinux-dist Bugs Item #5712] I2C client drivers using dev_pm_ops fail to
receive suspend/resume callbacks
Temporary fix:
Restore struct i2c_driver suspend/resume
