[PATCH v2 3/8] usb: ehci: introduce CONFIG_USB_EHCI_HCD_OMAP

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

 



From: Keshava Munegowda <keshava_mgowda@xxxxxx>

Introduce the CONFIG_USB_EHCI_HCD_OMAP option to select
EHCI support on OMAP3 and later chips. This scales better
than having a long line of dependencies for each new OMAP
with EHCI support.
