[PATCH] usb: musb: turn phy on

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



30a70b026b4cde4 ("usb: musb: fix obex in g_nokia.ko causing kernel
panic") broke USB gadget support on Pandaboard because it simply deletes
the call to phy_power_on() and the PHY is therefore never turned on.

Fix it by actually turning the phy on.
