Hi,
I have an imx53 based boards with an ULPI phy (smsc 3315) connected to
usbh2 and usbh3 and encounter problem with patch
"usb: chipidea: coordinate usb phy initialization for different phy type".
In drivers/usb/chipidea/core.c:ci_usb_phy_init, if I call
hw_phymode_configure() before usb_phy_init(), the system freeze. If I
call usb_phy_init() before hw_phymode_configure(), everything works fine.
So I wonder if someone test ULPI phy? and if the following piece of
patch (that works in my case) could be acceptable :

If not, the patch says that actual solution this is not the best
solution so what could be the better solution?
Thanks
