[PATCH] arm: omap: move OMAP USB platform data to <linux/platform_data/omap-usb.h>

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

 



In order to make single zImage work for ARM architecture,
we need to make sure we don't depend on private headers.

Move USB platform_data to <linux/platform_data/omap-usb.h>
and keep only internal functions in <plat/usb.h>.

Compile tested only.
