[PATCH v8 2/7] usb: rename phy to usb_phy in OTG

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

 



This patch prepares the introduction of the generic PHY support in the
USB OTG common functions. The USB PHY member of the OTG structure is
renamed to 'usb_phy' and modifications are done in all drivers accessing
it. Renaming this pointer will allow to keep the compatibility for USB
PHY drivers.
