From: Ben Chuang <benchuanggli@xxxxxxxxx> commit 291e7d52d19f114cad6cbf802f3f19ef12a011f8 upstream. When the system resumes from suspend (S3 or S4), the power mode is MMC_POWER_OFF. In this status, gl9763e_runtime_resume() should not enable PLL. Add a condition to this function to enable PLL only when the power mode is MMC_POWER_ON.
