This will cause mtu3 probe failure, so I will send new patches based on usb-next branch. sorry On Mon, 2017-02-06 at 17:29 +0800, Chunfeng Yun wrote: > Due to the reference clock comes from 26M oscillator directly > on mt8173, and it is a fixed-clock in DTS which always turned > on, we ignore it before.
