So I don't think we need this patch. Probably the drivers are enabling all their clocks at probe instead of understanding that the phy is outputting a clock that goes into gcc to be gated and then back out into their controller and/or phy. Also, note that these clocks have parents that should be populated by the phys, but so far we haven't done that. That should be fixed as well. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
